Dayton Audio SUB-1200 12" 120 Watt Powered Subwoofer is rated 4.7062 out of 5 by 177.
Rated 5 out of 5 by from I'm impressed!While it was larger than I expected it to be, it has great tone. I'm hearing new levels of bass. It replaced at Polk that died on me.

Rated 4 out of 5 by from DecentBought this with high expectations stemming from other reviews. Being a long time mobile audio guy I've experienced what extreme bass is. I wasn't expecting windshield flexing SPL out of this sub, but, I was hoping for a little more volume. I've got it running with a pair of B&W DM602 off an older Yamaha surround receiver @ 80 watts RMS. If I pull the power plug to the sub I barely notice it's gone and that's with the sub at full volume. Maybe it hasn't broken in enough yet or maybe I'm just a bass snob. However, after first opening the box and pulling of the, what seems to be heavy duty foam packaging, I noticed some scratches on the top of the cabinet. The thought of this thing being a floor model or a refurb is very real. It's not even worth the hassle to me to pay for return shipping or even wait around for RMA and getting a new one shipped to me.

Rated 5 out of 5 by from Pleasantly surprisedI bought this unit to give a system I am developing in a less than ideal environment a little better bass presence. It is doing the job very nicely, I'm glad I bought it!

Rated 5 out of 5 by from Good bass for the buckit is more bass then is needed in most cases if you want it to mx with your other speakers. but when i want to get down to some dubstep and turn it up its awesome. it shakes my house at certain frequencies. most people will be more then satisfied with this sub. i have a onkyo sr313 receiver and Dayton Audio B652-AIR 6-1/2". i have 2 book shelfs, but i need 2 more for this bass.

Rated 4 out of 5 by from Brought my Klipsch Heresys to another levelPurchased a pair of these. Using them under my Heresys [perfect height and size] they have brought them to another level and have added the bass they sorely need.Very nice quality for the price BUT the connectors are very fragile...one hard press and they will snap off ...beware, use gentle pressure when connecting the wires.

Rated 5 out of 5 by from Wow!I can't believe how great this thing sounds, especially for the money. I use it on my large covered patio and it booms the entire pool area and compliments my Def Tech AW6500's perfectly. Buy it.

Dayton Audio SUB-1200 12" 120 Watt Powered Subwoofer

I have a Yahama 377 receiver I just purchased. I plugged this sub1200 up and let it auto tune. Was a little underwhelmed. I think it may be due to my settings. What should set the gain, crossover and phase to prior to tuning?

Asked by: Shawshank
Set the gain to its midpoint, crossover all the way up, and phase to 0°. Underwhelming results can also be due to placement and room acoustics.

Can I hook my computer up to the sub via line level RCA inputs and hook my passive satellites to the high level outputs? Or will I need a seperate amp for the satellites?

Asked by: Bob192837
No, the high level inputs and outputs are a pass through and will require a separate amplifier for the satellites.

Is there a way to daisy chain more than one together?  I have 2 LFE outs on receiver, but thinking about adding a couple more subs totaling 4... If not, can I pair the 1200 with a more powerful sub for movies, or would that sound bad?

Asked by: Kobykat
Yes. you can use the high level ins and outs to continue the signal or use an RCA splitter for low level to continue the signal on to other subs.

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).
