Dayton Audio SA230 230W Subwoofer Amplifier
Dayton Audio SA230 230W Subwoofer Amplifier is rated 4.3846 out of 5 by 39.
Rated 4 out of 5 by from Life begins under 30hzWell, after 3 days of it sitting sideways on the shelf, it works very well. Didn't think the boost frequency, and gain would be such a pain, being on the back. Once set should be ok, but come on. Those pots would be fine as is "on the front". Also seems to be a 2, to 3db bump in the bass boost when set to 0. But can work with it set just under 30 Hrz with the 2db bump @ 0, on my mess. Really it worked out perfect, sounds / feels nice. Knobs feel ok. The push in & out thing is just something more that could go wrong. If not for this they feel like they could get bent easily. They do their job well though. Time will tell. So far everything I have got from Dayton, has been as reliable as a wood stove. Hoping for more of the same. This does work very well, and outside of a few quirks, is a good piece, for the price. I have no problems with hum, at any volume. (All grounds matter folks) I spent 20 years of my life tracking down, hum, back feed, hot grounds, ect. It's almost never the equipment, but rather wiring problems in the home. I like it for its flexibility, clean power, price point, and don't forget the free night light. Buy it, you'll like it.

Rated 5 out of 5 by from Extremely PleasedI bought this subwoofer amp to replace an old, NHT SA-2 amplifier that had been driving two, NHT SW2si subwoofers. The Dayton amplifier drives the two NHT subwoofers with no problem. It handles the 4 ohm load fine and has plenty of power to do the job. NHT told me the old SA-2 had equalization of some kind, but could not say of exactly what that consisted. Thus, I experimented quite a bit with the bass boost frequency and level on the Dayton (using familiar musical pieces for reference) until I was satisfied with the sound. In the end, it sounded best at practically the same settings to which Dayton had set it at the factory.I have not heard any of the hum to which others have referred (perhaps the fact that I have it plugged into a Panamax line conditioner helps). I have also experienced no difficulties with the auto on feature that works perfectly for me. I do find the loose feel of the nobs on the front a bit disconcerting and the light on the front was so annoyingly bright I had to cover it with 10 layers of matte finish Scotch tape.Other than those two, minor issues I am completely satisfied. It would have cost around $175 to fix the 20-year-old, NHT SA-2. For just a little more money, the Dayton SA230 is bigger and beefier (weighs five pounds more), is brand new, and comes with a five year warranty. I believe the 1% THD given in its specs is for the maximum power rating. I think at normal levels of use the distortion is lower than this (and a Dayton technical adviser confirmed this for me). I would not hesitate to recommend this amplifier to others.

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.

..... also, with audio quality, but not necessarily volume, being more of a consideration than my cost, would you recommend one or (if applicable) two of these, over the SPA 500 plate amps?

Asked by: Craig A
The audio quality will probably not be distinguishable between these two amps. For general headroom the SPA500 would be recommended for each, but the SA230 would work if your not interested in a lot of output.

Am planning to build a pair of subs usthe Denovo cabinets each w/a 4 ohm 10" Ultimax. If I read correctly, someone is using this amp to power two sub woofers. Would that work in my case?

Asked by: Craig A
The two Ultimax woofers would have to be wired in series which would present an 8 ohm load to the amplifier, which will only provide about 75 watts or so to each woofer. Ideally you will want one amplifier for each woofer in this case.

I have the sa230 powering a 12" woofer. The frequency range on the amp does not seem to effect the sound presentation wether set at 80 or 180. All I am trying to do is dial everything out of the frequency range, like voices, except for the bass or lows.

I recently bought a home with a passive in-wall Boston Acoustics sub.  I have a Sony STR DH750 amp.  Will this Dayton Audio amp work to power my sub? Crutchfield recommended the Boston Acoustics SA1, but I'm looking for something cheaper (and similar).

Hello, the description says 40-180 hz adjustability, but the picture shows 80-180 hz. Which is it?

Asked by: Chbiff
The crossover is adjustable from 40-180 Hz, the picture is outdated in this case.

I have two NHT VT-2's with 6 ohms nominal  Impedance and would like to bi-Amp these can i do this with two of these SA230 amps? My receiver is a yamaha rx-v1. 

Asked by: Chet P
If you plan on using one amplifier, you will have to wire the subs in series for a 12 ohm load. This will reduce output power quite a bit. Your best bet is to use two amps, one for each woofer.
