Rated 5 out of 5 by from Lot a' Boom for the Bucks!I hooked this sub to my Yamaha and it performed just as described. I did not know this little money could generate such sound. Some of the music and videos I listen to can get pretty loud, but this sub delivers the sound I expect.

Rated 5 out of 5 by from Great subI've had this subwoofer for a few weeks and i love it. Any boominess can be corrected by adjusting the gains

Rated 5 out of 5 by from Sometimes the reviews are right!...I was looking for a new subwoofer for the old, and i mean old, home theater when I came across the Dayton SUB1200. I'll admit I hadn't heard of Dayton, so I did a lot of research, and was impressed by the reviews they received. I ordered the SUB1200 for a crazy low price, received it 2 days earlier than expected, and slowly broke it in. After a bit of tweaking, all i can say is WOW! Even the GF, who knows little about good audio, was impressed, and started telling friends about how good it sounded. I will be ordering other items, in addition to another sub!

Rated 5 out of 5 by from Powerful but not boomy! Blend well with speakersBought this one since AV forum a lot of pepople recomend it. I need it for the action movies since my Klipsch is only 6.5" can't handle the dynamics... but to my suprise that this sub is very well balanced and it can blend pretty well with the speakers that I have. (Klipsch surround + Infinity floor standing P363)

Rated 5 out of 5 by from plenty of thump...Recieved my sub 1200 2 days ago and began the initial burnin time for it. I must say this, i did not expect this 129$ sub to perform as well as it is doing. This sub is in a small room (12x12x8). I set the gain to halfway , turned the crossover all the way up(am using dedicated LFE out on denon reciever). i used a single belkin cable to a y adapter and summed up the left/right inputs on sub.i Started out using moderate volume levels for about 10 hours to allow for the speaker to "loosen up". After 10 hours or so i put on some bass heavy tunes and started to bump everything except gain up, its still at halfway position mind you.lets just say, this sub is not cheap boomy sounding at all. has a nice very low growl, nicely held together, and is performing quite well for the cost.I have listened to subs ranging from 100$ up to about 2000$, and to be quite honest, while it is not a high end sub, it does very well at its attempt. There is nothing sonicallylacking really, its all here, and enough pressure to be pleasantly acceptable, to be frank, i actually smiled and thought,wow, not bad at all for the money.Let me end this by saying this, if your budget is under 200, get this or even better, get 2 of them, or the 15" version, for the money, they cant be beat!.

Rated 5 out of 5 by from Was worried, but after listening, now I LOVE IT!I was worried about buying this and not using the money towards a more expensive sub. For home theater use, let me just say this thing is AWESOME. I have about 1400 cubic feet and one dayton sub-1200 works great, but I'm thinking of adding another just for fun since they're so cheap and having two up front just looks cool. BTW, all this talk about how many hz will the subwoofer play and I'm not sure if using youtube videos are an accurate way to measure, but if I turn my receiver up this thing can get down to 15hz. At 25 and my walls start badly shaking. At 20 it's like an earthquake. 15 you can hear the driver moving and feel some air but that's about it.

I have a Dennon AVR-1513 receiver what cable comes with this subwoofer and will it hook up to this receiver?

Asked by: bobh1234
The only cable this subwoofer includes is a power cord. You will only need a standard RCA male to male cable to wire this to the receiver.

Will this work as a replacement to the included passive sub for my Samsung HT-F4500? Could I use the included sub along with the Sub-1200? If so, what woud be the proper way to wire it?

Asked by: Andy34
Yes this will work as a replacement for the passive sub, you will just have to use the speaker level inputs. Unfortunately there is no way to use the passive along with this subwoofer unless you get another sub amplifier.

Can this handle 20Hz  with a flat response? What about under 20hz (around 15 hz or so)? And lastly, how loud can it get before the driver starts to distort? Thanks :)

Asked by: TL1310
This subwoofer is tuned in the upper 20's so with room gain and proper placement it will reach pretty low. I doubt it will reach into the teens with much output.
