Dayton Audio SUB-800 8" 80 Watt Powered Subwoofer
Dayton Audio SUB-800 8" 80 Watt Powered Subwoofer is rated 4.8261 out of 5 by 92.
Rated 5 out of 5 by from Very nice!Have a soundbase under our TV with a subwoofer output. While the soundbase on its own is remarkably better than just the TV, this Dayton sub makes ALL the difference. All of its adjustability is awesome. We have it out of sight behind a chair to the side of our TV and it sounds amazing. Action scenes really pop and music is much more alive. Our soundbase is 65 watts and this 80 watt sub is perfect for our medium-size family room. Frankly 1/2 volume on the soundbase is almost too loud and this sub shakes the walls! Quality build, great price point, and terrific service from Parts Express.

Rated 5 out of 5 by from NiceSounds great with my old dBx satellites connected to a Denon AVR-S500BT.

Rated 4 out of 5 by from Does the job in a small room.The sub is fine for a small room and small main speakers. The 12db slope prevents these from blending well with full range speakers. But if your speakers start rolling off around 80 hz these will work great.

Rated 5 out of 5 by from Great product, performance and priceAdded this Dayton Sub to B652 speakers & Lepai LP-2020A+. All connected to my PC. Now I can enjoy Pandora and Spotify, as well as digitize my LP collection in wonderful stereo sound .

Rated 4 out of 5 by from Good subwoofer, excellent priceFully featured sub, with very nice assembly/finish, and most importantly, the fullness of sound I would expect from an 8" sub. Only complaint is that the AUTO on feature is not sensitive enough, and if you are listening to music at low volumes it will not kick in. Also, I have found that at times, especially at lower volumes, the auto ON/OFF feature starts kicking in and out several times within a few seconds. I think I'd rather just leave it in PERMANENT ON position. Other than that is a great sub.

Rated 5 out of 5 by from Awesome Sub, Killer Build Quality Best Bang $I have heard about Dayton off and on for years, I have never owned anything, Can I say WOW. For your $ I don't think it's even possible to make a better sub. The cabinet is incredible, Overall look and feel of the unit clearly states some thought went into it. The amp plate seems only to get warm at best even under heavy loads. I am 42 grew up on Zeppelin Etc. This thing makes my bedroom walk and my mattress becomes a vibrating bed. Once dialed in this shows no signs of cavitation or distortion. There is now sound or hum whatsoever at idle. I find using it with my 38" Vizio sound bar the Auto on feature works perfectly and almost instantly Packing was awesome as well box in a box. The people @ Dayton Clearly care obut there products as well as there customers. ORDER NOW !!!Derek.J Florida 1/29/2015

Dayton Audio SUB-800 8" 80 Watt Powered Subwoofer

I have a 2 channel receiver with A and B speaker outputs.  Is it ok to connect this subwoofer to an amp using high level in from B on the amp, and leave the full-range speakers on the A outputs from my amp without using high level out on the sub?  Thanks.

Asked by: gopanthers
You can wire it either way and get the same results. The speaker output on the subwoofer is unfiltered so it will be no different if you use these.

The Dayton Sub-800, does this act like an amplifier in itself? For example I am purchasing a pair of Micca MB42x's, can I bypass purchasing an amp, and have the Micca's powered by the sub? How many watts per channel would it be?

Asked by: Matt Simone
No, the amplifier in the SUB-800 is a dedicated amp for the subwoofer only. It will not run additional satellite speakers.

I'm looking at getting this sub to use with the B652-AIR speakers as a setup for my garage gym. Will this sub be good enough or should I get the 10" or 12"?

what is the idle time for auto off?  I have seen it turn off (red) in the middle of the song, normally when there is little or no bass, and then on (green) when bass kicks in.   But it can do so several times within 5 seconds.  

Asked by: Cris
The idle time for this is generally about 15 minutes. If you are having issues with it staying on at low volumes I would recommend bumping the subwoofer level up on the reciever and compensating by turning the gain down on the subwoofer. If this still does not solve the problem the output strength of the receiver might be too weak at low levels and we recommend leaving the amplifier on.

How many watts does this amp draw? I need to use a step down transformer as I have moved myself and the amp out of country. 

Asked by: SuperSecretAudio
I would recommend no less than a 200 watt converter for this subwoofer.

I am looking for a solution to my problem. I am planning on using an Emotiva mini-x a-100 mini amp to power a very small system. I have a pair of Dayton B652 bookshelves. I want to add a sub, but need to limit bass to book shelfs. How?

Asked by: PittViper
You will have to add an in line high pass crossover to the bookshelves. We have a few options available for this, but it depends on what frequency you want to cross them at. Usually subs are crossed around 80-100 Hz.http://www.parts-express.com/100-hz-high-pass-4-ohm-crossover--266-460
