Dayton Audio SA230 230W Subwoofer Amplifier
Dayton Audio SA230 230W Subwoofer Amplifier is rated 4.4722 out of 5 by 36.
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.

Rated 5 out of 5 by from Just a very nice productThe amplifier is housed in a nice basic metal cabinet, large bolt on the bottom which holds it's large transformer. The amplifier is completely quiet, I was worried about 60 cycle hum, no hum from this amplifier. Lots of good adjustments, it was a real upgrade to my Definitive Technology PF 1500 power plate, no comparison. I can see no downsides to this product, would purchase again in a heartbeat.

Dayton Audio SA230 230W Subwoofer Amplifier

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.

Will This Amp Work With Two Sc-8 Subs From Velodyne They Are Sealed What Would Be Wattage For The Two In Four Or Eight Ohms Thank You Very Much

Asked by: ron8773
This amp will produce 156 watts into an 8 ohm load (78 watts per sub) or 233 watts into a 4 ohm load (116 watts per sub). This will work as long as both subs wired together do not dip below 4 ohms.

Will This Work With Two 8 Ohm Speakers One In Each Box Will This Bring It To 8 Ohms In Series Thanks

Asked by: ron8773
Two 8 Ohm speakers in series will result in a 16 Ohm load.  Your best option would be wiring the two speakers in parallel for a 4 Ohm load.

The amp in my M&K (Miller & Kriesel) Volkswoofer 1B subwoofer failed so can I use this amp and connect it directly to the M&K speaker bypassing the M&K subwoofer amplifier?

Asked by: Joeh10
Yes as long as the woofer impedance in the subwoofer is 4 ohms or higher.
