Dayton Audio SA70 70W Subwoofer Plate Amplifier is rated 4.1898 out of 5 by 137.
Rated 4 out of 5 by from Works well with a good speakerI use a large sealed, stuffed box with an efficient driver and the power of this amp is just fine. It was the work of a few minutes to mount the plate and wire it up. The first one I bought developed a little "groan - buzzing noise" periodically - that's why it did not get 5 stars. Overall, it is great - I can shake the floor if I want.

Rated 4 out of 5 by from Power for your music's lower two octaves: the SA70 amp.The SA70 arrived on schedule, as promised. I have put it in a box (0.6 cu. ft.) with a Tang Band 6-1/2 inch driver (PE #264-832). The Technical Department offered advice about proper tuning of this vented system. In initial listening tests, it performs better than an Advent 12-inch sub in a larger box (ca. one cu. ft.). Besides moving large volumes of air, it renders musical pitches well, so that the music has better definition from low to high notes. Imagine the lower two octaves in your recordings solid & defined without breathiness (the 'woof-woof' effect). The performance of the SA70 did not surprise me, since I have also used it to drive 8-inch drivers. It offers good value for the dollar.

Rated 4 out of 5 by from Dayton Audio SA70 70W Sub AmpNot a bad little amp for a smaller, don't have to fill the room with bass" kinda system. Used mine on a my custom built sealed enclosure 12" sub to go with my AudioEngine 2 Speakers connected to my computer. Sufficient low end 40hz was a little higher cutoff than I wanted) and basic volume control. Sealed enclosure and small package make it an easy fit, does not take up too much internal space. For the price, its an excellent choice, otherwise... if you want tons of volume, spend wisely.

Rated 5 out of 5 by from Better than stock 250w JBLI have a JBL Venue 10 sub that cooked. I got creative with a hacksaw blade in my jigsaw and cut an opening out of the stock JBL plate amp, screwed it in, and it looks factory.The SA70 amp itself was heavier than the stock 250w JBL when held side by side. Once the plate was prepped, installation was very easy (though I wish the leads to the driver were longer). The sound is amazing for a $50 sub amp! I think it may be an upgrade from the 250w JBL factory amp! Brings my basement workbench to LIFE. It was a perfect fit for this refurb/repurposing of a cooked asset. I'm glad I didn't kick down bigger $ for more wattage in this case!

Rated 5 out of 5 by from Great deal!Plug & play- My previous sub plate amp went out on my little 8" 4-ohm sub. So I bought this cheapy, and it works just as well. I didn't test the crossover, since I use the sub-out crossover in my A/V receiver. For the money, this is a really good deal. It works great on smaller subs. It's been going strong every day for a month with no problems.

Rated 3 out of 5 by from JUST BOBDisappointed with this amp.For a sub there to much higher HZ getting through.When I turned on the unit it sounded like a mono speakernot a Base speaker.The only thing I can thing of to getting rid of the mid range sound is a cross over to filter out the mid range HZ.I found a SONY SQR 6650 4 channel receiver made in 1973.Living in a 5th wheel RV there not much room for such a receiver.I installed these little 2 inch speakers along with a 6 inch sub woofer. (All sold by Parts Express)The Tang Bang model W2-18118 2 in speakers were just installed right into the walls no cabinets. 6in Sub in to a unused cavity.The 2in speaker have a HZ range from 150 to above 15000I couldn't believe my ears when I turn on the receiver. The little guys were putting out base. Ya BASE!All in All. I'm very happy with this old Quad stereo it has a awesome sound. Its 4.1 not the new 5.1 along with mycassette and LP's I have a system anyone would love.If you saw a 70 yr old doing cartwheels it would be ME. :)It a shame Parts Express discontinued carrying theseawesome little speakers.

Rated 4 out of 5 by from Perfect for the right applicationLet's be realistic about this product. This subwoofer plate amp runs 70 watts RMS at 4 ohms. At 8 ohms, it's going to run at 45 watts RMS. This is not going to shake doors off hinges or break glass. It isn't supposed to.For the average living room on a modest budget, this amp is great. If you're looking to add a little extra to your home stereo and TV watching experience, this is a good choice. I see a lot of people that cannot help but to go maximum power in anything they purchase when it just isn't necessary. These plate amps are a good example. Some people also expect extremely precise, error free, best-of-the-best type quality out of even the most inexpensive of items and they are inevitably disappointed by a product with results that are good but not amazing. This plate amp is also a good example of that.I bought this more out of curiosity than any other reason. I had been given an old Fisher sub woofer cabinet (ported) without it's own power and a rotted out cone. I also had a 12" 3.7ohm, 120w Goldwood poly woofer lying around so I married the three: Fisher cabinet, GW 12" woofer, Dayton 70w plate amp. Not "top of the line," high quality items but doing this makes these components out of storage and in use, as opposed to being dust collectors.Of course it isn't George Lucas' soundstage, it's just a simple subwoofer capable of making home entertainment better than NOT having a sub at all. I set this up in my shop, a separate building behind my house. I put it through its paces and let it run all night at about 1/2 volume after I went to bed to see if it got real hot, blew up, anything bad happened. The amp worked fine all night. It worked too well because I was woken up by the local police department banging on my back door. Sound complaint, could I turn it down. Actually, he asked "Did you have a party here last night?" And then he told me there was a complaint.I think that tells you this is not garbage with no output power. It was loud enough at 1/2 power to get someone to call the cops. And the nearest place besides my house that a person could be is about 90 feet, inside their own home. So loud enough to be audible from inside my shop, 90 feet away, inside a house. That is kind of my unofficial measure for success in the "is this loud enough?" category.I've found that I like hooking up this amp via the low level RCA connection rather than running a stereo set of speaker wires to and from it. Less mess and I like the sound better.Now. The Crossover. It is not a piece of garbage, as eluded to here. It just has way too much headroom. You shouldn't be able to have crossover frequencies as high as this one allows. You'll be pushing vocals and instrumentation not meant for subs and it will sound.... like garbage. Keep it turned LOW and I mean all the way down if not a tiny tick from all the way down.This thing would be fun with an 8" or 10" in an enclosure that is shallow, with spikes, pointed downward. I am only going to get bigger, more powerful plate amps after my initiation with this one. I always thought the concept was great, but hadn't tried one out. Now, I am in love with this product!Over all, this is a great addition to your home entertainment center if you are in a somewhat run of the mill situation with your normal sized living room, a TV you watch some movies on, hooked into your stereo that you also listen to music on. Adding this amp w/ a matched sub to that sort of situation can only make your audio experiences better.If you're looking to add a powered subwoofer to your 80" LED Internet TV on your 7.1 surround system with Left and Right floor cabinet mains powered at 200w RMS and each of the five other satellite speakers at 140w RMS in your 40 foot by 60 foot home theater- this is not the product for you. This is probably something a person like you would want installed for his second bathroom audio system.

Rated 4 out of 5 by from Need more powerThis did not have enough power for the subwoofer I was repairing. Decided to return it for the 250W one.
Date published: 2013-05-04
Rated 3 out of 5 by from Seems cheap...I had this powering an 8" Dayton sub for about 2 months and it started sending a hissing noise with an odd chirping sound every couple minutes. It sounded alright for a while. Terminals are also annoyingly small. Output seemed kinda sporadic. Filters are pretty much useless. I sent it back for store credit so I'm gonna try out the 100 watt model. Hopefully have better luck.

Rated 5 out of 5 by from Works Great Exact Drop-in Replacement for KLH subwooferI had an old KLH subwoofer that worked great for over 10 years. The plate amp finally died. I took measurements and ordered this one. It is an exact replacement, cutout and screw holes are identical to old one. I noticed that the old one had the model number as SA70 same as the new one.
Date published: 2013-01-03
Rated 4 out of 5 by from Not a bad choice at all.Believe people when they say the crossover is not great. It's more of a tone knob, doing a general high or low option kind of sweep. With an accurate ear, you can get it pretty close.Past that, it's powerful and well built.Pretty good amp.Great price!

Rated 4 out of 5 by from Great while it last, which seems to be around 4 years for most.I have installed several of these in small sub-woofer systems and the sound is great and they last reasonably well but I have 5 dead amplifiers in my possession now two of which I know the complete history of. One was in my Moms system and the other in a computer system of mine. Both were in use about 4 years before they quit working, neither were ever moved after being installed or ever ran to their maximum potential. I guess four years is a long time but that seems to be about their life span.

Rated 4 out of 5 by from Good amp so far, crossover is an issueSolid little amp. Replacement for the dead amp in my Polk PSW202 (known to have this issue apparently). Just enlarged the opening a bit and mounted on its side. Had read issues about xover so ordered a passive 80 hz high pass with the amp. Wise move. Amp as tested does medicore job filtering signal well. Addition of 80hz xover cleaned and tightened things nicely. Total price with shipping under $100 (more than I would have liked to have spent).... but saved the rest of the polk from the landfill. No phase control... no heat sink.. but seems fine so far. Sub in small 10x20 room with Sherwood 100 watt receiver driving Mission bookshelf speakers... very nice! Kudos to tech support for a quick answer back to my question... and for FAST shipping!

Rated 5 out of 5 by from Great price for a Great little amp.I bought this amp for an 8" sub project. The price made it a no brainer. The first one I received was defective. Customer service sent me another unit the next day and paid for the reurn of the defective one. Once I installed the replacement I put the system through the a frequency bass test and it was better than I expected. The amp surface gets hot running 30hz tone for 15 minutes but, I think the back plate is the heat sink. Sounds good, great price and, outstanding customer service.

Rated 2 out of 5 by from Good amp, crossover still an issueSeveral reviews indicated that high frequencies were coming through to the speaker no matter what the crossover was set at. This is still the case with the SA70 unit I purchased two weeks ago. The bass coming out of the sub is very muddied. A return is not really an option when the hole cut in your cabinet is sized for this amp. I'm hoping a low pass 100hz RCA filter plug will remedy the problem, but keep asking: Why should I have to do this? Great price point, but beware...

Rated 4 out of 5 by from SA 70 SUBWOOFER AMPThis thing is probably one of the best home audio purcahses for me in a long time. I am running a Pioneer 7.1 700 watt home theatre stereo with Polk audio satallite speakers and a Coustic 10 in. sub from Parts Express, and this amp. I have never turned this up even over half way, my house cant stand the SPL the power this thing delivers during blue ray movies is unbelievable. The only thing I must say is, the ability to turn the bass all the way down in hindered, but if you can stand alittle bass in your newscast then it's not a problem but this unit is worth it and I have had this for over two years now and never have had an issue in performance at all. I buy all of my component items from Dayton and Parts Express now.

Rated 2 out of 5 by from The crossover makes this almost useless as-isThis amp is unusable as it comes if you have to put a full range signal to the line input. The crossover is terrible. On the sub I built, I hear vocals.I tried it on a dedicated subwoofer line out and it was fine, but this is not how I plan to use it. I had no choice but to clip the output wires before trying it, so I don't think I can return it. I would if I could. As it is, I'm going to have to add some more low pass filtering either on the input or the output to get it to work. It would have been a good value, but having to add another $25 of crossover parts makes it not such a great deal.It would be nice if you could reverse the phasing, but I knew it didn't have that feature going in to the deal. In all other respects, it seems a nice little amp. If you're going to use it with a subwoofer input, it should be fine.

Rated 4 out of 5 by from Good price, solid performer, but not perfectI have used several of these to drive single Aura Bass Shaker units. They work well in this application, but would be better if: 1)they had a detachable power cord ( think computer power supply IEC type plug) and 2) Turning the power off is more of a standbye.....when you leave it plugged in to the AC outlet the power light stays on and the unit stays warm. This makes me a bit nervous and compels me to unplug it when not in use.

Rated 4 out of 5 by from Good deal, Good performanceI bought this amp to replace a 55W, factory Klipsch amp in a powered sub. Couldn't find a factory replacement, so I figured I'd try the Dayton SA70. With some modification to the enclosure, it dropped right in. Sounds better than before. This thing works great. Very pleased with the performance of the amplifier.The only thing that's needed is an adjustable frequency boost, it does just fine without it.
Date published: 2012-06-08
Rated 3 out of 5 by from Horrible CrossoverI gave it 3 stars because of the price, but the crossover is horrible. The sound changes when you adjust it but a lot of upper bass bleeds through. It makes the sub sound very tinny. I added another sub crossover that I had from my car and it was a night and day difference. I currently have it hooked up to a 8 ohm setup, I am going to try a 4 ohm setup and see if I can get even better sound.
Date published: 2013-05-04
Rated 4 out of 5 by from Superb equipment for small projectsThe amplifier came and was ready to be put in service.The instructions for setup, were easy to understand, so it was able to have amp placed in service in the system it was to operate. Very happy with the purchase.

Rated 4 out of 5 by from Terrific ValueI am extremely pleased with this amp. It has been running in a subwoofer enclosure with almost no ventilation now for over 4 years and it still sounds great. I was very surprised with the amount of output. If there is anything at all I could complain about, it has managed to pick up a little bit of a hum. That could very well be my own fault though.

Rated 4 out of 5 by from Nice itemI custom installed this subwoofer amplifier in a pinball machine that I was restoring. I used a 4 ohm set up for maximum power and this Dayton Audio piece really pumped out some bass. I also have the smaller Dayton sub-amp on a surround sound system in my den and it is nice as well. (The picture shows the amp cover removed because I did an all rear internal custom hook-up)

Rated 5 out of 5 by from works good up to a 100W /Channel systemI have a 100W/Ch receiver and I have to set the sub amp on max for a good balance of frequency.If you have over 100W system, you will want to go to a higher output sub amp.Currently my sub is cut into a passive sub (from my old system) and is on an 8" woofer.
Date published: 2011-11-10
Rated 3 out of 5 by from Decent amp but low pass filter is virtually non-existantLike other reviewers have mentioned, the low pass filter even when set to the lowest frequency barely filters mid and upper bass notes. Not too much of a problem if your setup already includes a crossover. Mine runs warm even when in standby mode. Runs hot when driving low impedance loads, but has surprising amounts of volume, and has not shut down due to heat. Sound is decent, not super articulate like you'd get with a larger amp. Overall, I'm luke warm on it and will keep it just based on low price.

Rated 4 out of 5 by from Great little amp.. needs outboard crossoverI purchased this amp to power a little ported 6" sub that I received from a friend. The sub box is about the size of a mini-tower so I figured it couldn't be all that bad. I also purchased an 8ohm 100hz outboard crossover after reading a couple reviews on the amp. I'm very glad that I did.Without the crossover the amp plays well beyond the advertised 180hz. After plugging the crossover in, it sounded much better. I knocked a few points off on Features for that reason. Aside from that the auto sensing works fine, and the high/low level inputs are a nice touch.

Rated 3 out of 5 by from Sub average performance with a very poor crossover.The amp was replacing a dead amp in a Boston powered sub. After getting all the mounting worked out and plugging her in I was a little disappointed. First If your source has no LPF on its output you will be in big trouble. I had had mine disabled when I first tested it out otherwise I would have never noticed the built in LPF failure. Even with the knob set at 40Hz it only dulled a 200hz sine wave being fed into it. Leaving it at 40Hz LP and playing music you could hear all the vocals up to around a thousand hertz. This would pull your sound stage way off and be very annoying if you had to live with it.Now getting beyond the crossover we step to the output.I have a very hard time believing this thing puts out 100 watts at the distortion rate it claims. I do not have the tools at my disposal to test this theory so I can not say this for fact. I am no electrical engineer but I have seen a number of amplifiers from different makes and this one just seems to be the cheapest build quality I have come across. I know its target price point is not real high so I can not fault it to hard for that. I did hook the sub to a known 100watt car audio amp and it had no where near the authority or head room on transients that the car amp had.So to sum it all up. If you do not have a LPF on your source avoid this unit. Wattage may be a little over stated.It is possible I have a defective unit.

sin't there a volume control?

Asked by: jalng63
The "Gain" control effectively performs the same function as a volume control, insofar as setting the maximum amplitude of your subwoofer. When used with a standard home theater receiver, the volume control on the receiver will control the relative volume of the subwoofer, and the "Gain" setting on the subwoofer sets the maximum overall volume for the subwoofer.

Help me understand the "low level input".

Looking to power 1 Aura Pro Bass Shaker for my drum throne.The input to this amp would be a send from the mixing board with only my kick drum mic. Would that work into the "low level input", or would it have to come from a subwoofer out on an amp? Thanks!

Low level input is unamplified signal, also called pre-amp or line level. Do not connect this amp to another amplifier unless the connection is stricly line level.

full range?

Does this amp have the ability to run full range?I might like to put one in the back of a portable supertweet enclosure.
Asked by: Calaveras
I thought it might be helpful to add to my previous in regard to modifying the SA70 for full-range use. I did the mod to the SA70 about 6 years ago so had forgotten the details, but I thought it might be helpful if I snapped a couple of better photos with some labeling in case you wanted to do the mod yourself.The power switch still works (ON and OFF positions only), but none of the other controls do, nor do any of the jacks - this mod bypasses all that.

At this price point, you are not going to get sophisticated crossover components. If you have an LFE or sub out of your source unit with its own internal crossover - you should be fine.

Can this amp be used in Europe with 220V?

I live in Latvia and we dont have 110V outlets only 220V. Is there a way to use this amp with 220V?
Asked by: Maters
This device is listed for use with 110 Volts. The only way to operate it with 220 Volts is to purchase a step down voltage converter. Be sure to get one that has a capacity at least 50% more than the watts consumed by the unit you wish to operate. Most converters are fused and have euro plug style adapters so you can plug into the wall overseas. Then you are ready; Good luck!

Will this work with my home stereo?

Ok I bought a sub the other day and it was just the box with the speaker, no pre amp, not even terminals on the back to plug in speaker wire. I don't know how to hook it up to my current system and have it work. The system I have came with a sub with a pre-amp built in but I wanna upgrade with the sub I bought. I have no clue how to hook it up or what kind of pre amp to look for. All I know about the sub is that the speaker has and 8 ohm, 50 watt max on it. If you could help me out, or at least tell me what I should be looking for, that would be great.
Asked by: Dustinmcall
Yes, as it is designed to do just that.You'll have to cut a hole in the box for the amp to fit, but wiring the subwoofer speaker to the amp is simple, and the sub amp has all the connections you need to run it from your stereo.Don't worry about the power rating difference, it will not matter.

Asked by: BALER
It is best to use a separate amp for the bass shakers and not try to run them and your sub from the same amp. If you have a sub out from your receiver, you can "Y" jack and run one line to your powered subs and the other line to the amp driving the bass shakers. Each amp has it's own level controls so you can balance the system.

Looks like most all the plate amps are sealed cases. Doesn't this cause major heat buildup?

Is there a built in HPF to protect from over excursion on ported builds?

Asked by: rawls
I believe there is a sub-sonic filter at 19Hz rolling off at 12dB per octave, but that alone won't protect a woofer from over-excursion. The woofer, enclosure and port size must all be factored in as well as the amplifier power. The Tech's at P-E will be more than happy to assist you with this, however. Also the people on the "Tech-Talk" forum can help you.

The only way you can safely wire three 4 ohm subwoofers to this amp would be to wire them all in series, which will only provide about 23 watts of total output power from the amplifier. You would be better off using 4 subwoofers wired in series/parallel and a slightly larger amplifier.
