Dayton Audio SA230 230W Subwoofer Amplifier
Dayton Audio SA230 230W Subwoofer Amplifier is rated 4.3784 out of 5 by 37.
Rated 1 out of 5 by from I was rather disappointedI bought one of these a year ago to power an Infinity TSS-1200, which had developed a fault in it's amplifier. I bought it, wired it up properly, and the darn thing hummed, even at low levels. I consulted the rather thin manual, and low and behold, Dayton knows about this hum problem. One of the things they suggest doing is disconnecting the coaxial connectors to satellite/cable boxes. Actually did reduce the hum to nearly tolerable levels. I have a DirecTV HD receiver/recorder with two input connections for recording two shows at once, and those coaxial line grounding things the booklet suggests buying are not only expensive, but rare as hen's teeth. What's so hard about the concept of a device working properly right out of the box without having to buy a bunch of other stuff just to make it work sort of properly? No, I will not and should not have to go through that. So I sent the unit back and bought an NHT SubTwo from someone on the used market for $300. Those things have a 500 Watt Sunfire amp powering TWO 10 inch drivers in a sealed box, a nice external controller which can handle two in stereo if I got another one, which I plan to do, and the amp when on with no signal input is as silent as the tomb. Meanwhile my poor Infinity is sitting in a corner being unused until I MAYBE someday down the line find something better to power it with. Surely I can't be the only person to ever have had this problem. However Parts Express were easier to work with concerning returns than this blasted Chinese box.

Rated 5 out of 5 by from Versatile and Does the job very well!I needed a sub amp with between 225 and 275 watts that will drive a definitve technology in wall sub woofer which had a 4 ohm 10" woofer. This amp can handle a load starting at 4 ohms. It drives it very well and is built nicely. The auto sensing circuit works great too! So far it is awesome. One thing that could be improved upon is the Standby Light is really way too bright, it lights up my living room at night, lol. Maybe they should call it the standby ambient light feature? Anyway I still love it, why spend hundreds more on an amp that has a short term warranty anyway when you can save a lot. This Dayton Amp comes in a great packed box with no frills expensive printing on the outside to raise the costs to the consumer either. I give it five stars.

Rated 5 out of 5 by from Got good advice from Parts ex technical dept.This is Subwoofer -amplifier is just the right power for my speaker. It sounds better than the one it replaced. I'm very pleased.

Rated 4 out of 5 by from NiceNice build quality, reasonably hefty.Brushed faceplate makes it a nice looking amp.Recessing buttons on the front panel are a nice touch and make it harder to accidentally change settings (though they're not exactly hefty, so good thing this is not meant for a pro situation).A few things:i thought the variable phase control would help it blend with the mid/hi speakers, but it didn't in my application (ymwv).The bass boost is active *even when set for 0db*. So if you have it set there, don't think the frequency control has no effect, it does ! you're still getting ~2 boost ( I did extensive measurements with omnimic on 2 units). And when the boost is turned up it can get pretty massive. You might like this, but I was going for a flatter response, since my speakers are already pretty good down the low 30's. Also the controls are ridiculously hard to access on the back panel, requiring removal of a plastic cover and a mini screwdriver to adjust.Also ( probably not a big deal, and may not apply to most), when daisy chained from the back of another amplifier (Emotiva, for a fullrange system) it brought the level down by 1- 2 db. I tried 2 other sub amps and only this one did that.Overall I prefer the SPA500 because the parametric EQ is more flexible, plus it has higher power and a higher LP point @200Hz. All of which were better for my application.

Rated 3 out of 5 by from Great amp, except...I am using this amp to drive the woofers of a pair of Polk RTiA7s. A Denon receiver is doing the x-over duties and driving the upper end. It is amazing how much better the system sounds with bi-amping compared to just using the receiver.Very nice amplifier, except for the auto-on feature. It needs a fairly high level input to turn on. Listening at normal levels will not trigger the auto-on or keep the amp on. You have to really be rockin' it out to turn the amp on and keep it on. At least with my set up. So, for now, I am manually tuning the amp on and off. Not a big deal. But in this day and age, an amp ought to know when it has a input signal or not.I design circuits for a living. So when I get a chance, I will open up the amp and find the input to the comparator that triggers the auto-on function. It should be an easy resistor change to increase the sensitivity of the auto-on function.If the auto-on worked better, I would give this amp a 4 start rating. 5 stars if it wasn't made in China.

Rated 5 out of 5 by from Good amp for Bass ShakersI bought this amp to run 4 bass shakers in series-parallel. I have been impressed with the amp and its adjustments to allow me to fine tune the shaking with my subwoofer to get the right amount of sound and shake. I have 2 reclining two-seaters and mounted a pair on each and there is incredible shake and room for much more if I turned up the LFE channel and increased the gain on the amp. I looked at Dayton Audio SPA250 250 Watt Subwoofer Plate Amplifier as well. For my use, the $75 was worth it to not have to build a cabinet or mount it in the wall and buy various other parts to make a clean installation. I was also fine with the trade off of 233W with this amp versus 252W with the plate amp at 4 ohms. Because all the amp is doing is shaking my chairs I don't think the THD of 1% is relevant versus 0.1% for the plate amp. One minor downside, as mentioned by another reviewer is that the auto-on requires much higher line level to trigger than my sub, though at theater listening volume it does come on, however with music listening volume it is less likely to turn on. Also, as mentioned by another reviewer, the 12v trigger requires attachment of wires rather than a plug. Overall I would highly recommend this amp for this particular application.

Dayton Audio SA230 230W Subwoofer Amplifier

Hi, I bought this amplifier to drive my outdoor subwoofer, the Polk atrium 10 (http://www.polkaudio.com/atrium-sub10/d/1072C2901) which amp settings should I use for phase and frequency? (I understand that gain is kinda like volume)

Asked by: TLCDesignLab
Phase and frequency need to be set according to personal taste. Phase will change the blend between the subwoofer and full range speakers. Generally this is either set to 0 or 180 degrees, but you can play with the different settings until it sounds right. Frequency determines how high the subwoofer will play. If your full range speakers play down to 100 Hz for example, you will probably want the crossover frequency somewhere around 100 Hz.

I don't have a 12v trigger out on my receiver so I'll need to use a 12v wall adapter instead. How many amps should the 12v wall adapter be?

Asked by: midnightwatcher
The trigger input on this amplifier requires no more than 50mA for it to work properly.
Answered by: MattP
Date published: 2015-06-11

What cable do you need to hook up the 12v trigger from the receiver to this amp? The sub is constantly shutting off during movies and then coming back on when bass is present. The trigger output on my receiver is a 3.5mm jack, trigger input is different?

Asked by: brinohead
This amplifier has a small two conductor phoenix connector for the trigger input, so you will have to use a 3.5mm cable and cut one end off in order to use the trigger. This will allow the amplifier to be powered on or off whenever the receiver is on or off.

Am purchasing this amp to drive a single 10 in. Dayton RSS265HO-44 dual voice coil subwoofer. Is it better to use just a single coil (4 ohm), or use both coils in series (8 ohm); or no difference ?

Asked by: over
You will want to use both coils if you don't want the woofer parameters to change. Wiring them in series would be the best option in this case.

hey i just wanted to know i wanted to buy 4 auro pro bass shakers and need an amplifier for them would this hold all 4 or do you have one that will and also do i need a normal subwoofer to make them all work or not hope to here from you soon thanks

Asked by: toah
Yes. If you wire the bass shakers in series/parallel and maintain the 4 ohm load this amp will be fine.

I recently purchased two Dayton Audio SUB-1200's and I'm going to be purchasing two Dayton Audio Sub 1500's. Would you recommend using this to preamp the plate amplifier, for longevity purposes, or would I be wasting money doing so?

Asked by: Sevual26
This is an amplifier, not a preamp. It will only work with passive subwoofers, or subwoofers that don't already have built in amplifiers, so it will not be beneficial to you in any way.
