Rated 5 out of 5 by from bass bass bass!!!!!i brought this subwoofer a month ago and its shakes my house it doe's not sound like 120 watts more in the the 300 watt and when its at 140 hz its more boom at the 40 hz level everything shakes
Date published: 2015-02-24
Rated 5 out of 5 by from does what it claims it can doSeems fairly linear between around 28Hz and 80Hz. As always position of the sub is really important. The sound is very clean, not too boomy. I'm thinking about getting another to fill my large room. For $124 I don't think I could hand gotten anything better and to get something noticeably superior I would have to spend much much more money.

Rated 5 out of 5 by from Way better than my Yamaha HTIB sub!I got this a few days ago and it delivers punchy, deep, clear bass with no boominess, noise, or harshness. It's part of a 5.1 setup that started life as a Yamaha HTIB but earlier this year I changed the front 3 to Sony Core Bookshelves and Center and now the sub to this Dayton 1200. For the money, you can't do better than this sub and with a 120 Hz crossover it sounds incredible and really brings my movies to life in a way my old sub never could. And it does this while sounding very smooth and natural, which makes listening at louder volumes easier on the ears and much more enjoyable.

Rated 4 out of 5 by from Very Good Budget SubI bought this as a Christmas gift for a family member. It sounds quite good, and does so for both music and home theater. It doesn't quite rate with higher priced subs, but it's an excellent product for the price.Recommended for anyone who needs a good sounding sub for a low price.

Rated 2 out of 5 by from Somewhat Disappointed...I was going to write lots of technical details here about this Dayton Sub but, I later thought that it was not worth it only because for, $149.00, how much "true-bass"can you get?To sum it all I will only say that, if you want a "Boom-Box" then, this is for you but if you want real deep defined bass, definitively this is not for you.I have a 10" sub from HSU that truly goes deep into your guts (well below 25hz) it shakes the whole house and this Dayton unit does not even come close and having a larger 12 inch driver.It's tuned enclosure peaks at an annoying 60 to 75 HZ and below this, the frequency rolls off very quickly.I have not been able to make it go that deep as Dayton claims....but, again, for the price, I guess is ok.

Dayton Audio SUB-1200 12" 120 Watt Powered Subwoofer

I'm going to use this unit with an Outlaw RR2150 Receiver with built in Bass Management  it has an internal crossover that can be set to 60, 80 or 100 Hz.  What should I set the switch to on the Rcvr and what should I set the Sub's controls to?

Asked by: Gregoire
See the question below for more details, but set sub's crossover to max (140 Hz) and the receiver's crossover to whichever sounds best with your main speakers. 80 Hz is a common recommendation if your main speakers have enough extension (low point in frequency response).

i have a onkyo sr607 using audyssey.. just wondering if anyone would what the best crossover setting would be when running the program

Asked by: Animal0jg
The crossover on the sub should be at max (140 Hz). The crossover on the AVR should be at whatever level is right for your main speakers (front, center, surround). You could factor in the woofer size on each of those main speakers as well as the rated frequency range (low point specifically). I use 120Hz on my Yamaha AVR (which only has a global setting, not individual by front/center/surround) since my surrounds have 2.5 inch woofers and are rated down to 90 Hz. My AVR also offers values above 120Hz like 160 Hz and 200 Hz; however, they are beyond the range of the subwoofer (maxes at 140 Hz) and also using such high values can cause sub localization issues and/or dialogue coming from the sub. My AVR always chooses 80 Hz when running YPAO, but I feel that's less than optimal... that's why I change it to 120 Hz afterwards.

What the max spl?

Asked by: Willie Earl

How sturdy are the built-in feet on this sub? Can I slide it along the carpeted floor without causing any damage to the feet?

Asked by: HT_GUY
The feet on this are quite sturdy. They are injection molded plastic with a flat bottom, so sliding it on carpet should not cause any issues.

What is the difference between this subwoofer and the SUB-120?

Asked by: JG19
Hey, I have been researching this. I had two of the sub-120's They do pretty good. I believe this will do better. The 120 has a rca pass through on it where the 1200 does not. The 120 has two ports on the back that are rear firing. they are loud. Maybe not that bad. but there are two ports on the back that are not rounded or anything so there is some noise. I have wanted to buy one of these but havent yet. Buy it.
