Dayton Audio SUB-1200 12" 120 Watt Powered Subwoofer
Dayton Audio SUB-1200 12" 120 Watt Powered Subwoofer is rated 4.7135 out of 5 by 185.
Rated 5 out of 5 by from Excellent!Bought this about a year ago, when I was rebuilding my 5.1 setup. It is setup with 2 pioneer Andrew Jones fs52 towers, 2 AJ bookshelves for rears and the matching center. All this is powered by a Yamaha rxv 465 receiver. Room is 16x22. This sub is the budget king! Excellent for movies! Fills the room! A little boomy for music but II have yet to fiddle with my sub trim settings on my reviever. I got this sub on sale for 104$ delivered, but even at the regular price it is far superior to my 12" klipsch I had before. This is an unbeatable sub for anything under $300! I may get a second once they go on sale again. I did originally place it in the corner, but did the "sub woofer crawl" and ended up placing it middle of rear wall, sound and output quality improved considerably!

Rated 5 out of 5 by from Been enjoying my awesome SUB-1200 for over a year.I bought my Dayton Audio Sub-1200 about a year ago, and since then have been breaking it in, and fooling around with different speaker configurations. I gotta tell ya, this sub is totally awesome for Home Theatre when hooked up to nothing more than a pair of old Optimus Pro-7 speakers! I've never really cared for 5.1 setups and don't even bother with them these days, although it would probably be great for that too, if that's your thing. That said, there does seems to occasionally be a wee bit of nasty cabinet resonance from very low musical frequencies (classical mainly), but I haven't noticed it in any movies or TV shows yet. Knocking on the cabinet makes think that some cross-bracing would probably be the best solution. Be that as it may, I prefer my 12 in. three way speakers (overhauled almost completely via Parts Express btw) for my musical enjoyment anyway, and this subwoofer doesn't seem to really add all that much to those babies. Best use I've found is for Home Theatre in my family room. All in all, very satisfied with this purchase.

Rated 4 out of 5 by from Gets the job doneDo a good job of filling out the low end. Nice for HT but almost unusable for music.

Rated 5 out of 5 by from Don't judge until it's tuned and broken inOkay, for years I have done high end stereos and really haven't played around much with surround sound (never saw the need and didn't want wires running everywhere). However a couple of months ago I inherited a Denon AVR-687 from my Nephew for free (he worked doing high end home theater installs). Having a decent amp for free was a game changer since I was looking at adding a projector and having at least a 5.1 channel system on the cheap was a no brainer in that context. I got some great polk audio surround speakers for $85 from a couple of different pawn shops, but the 8 inch sub that came with one set was way too small and weak for my living room and was muddy as all get out. I sold the sub for $15 to another pawn shop and focused on trying to get the best sub for the least amount of money. After doing research at AVS Forums and having a disaster with a Klipsch Sub-12 with a bad amp (never worked), I had to go cheap to convince the wife after the failure with the Klipsch and thus the Dayton SUB-1200 was the only real choice. I went to retailmenot to get the coupon code for $10 off $150 or more and added a $2.98 HDMI cable to the sub to get the discount, so I got the sub for $138. Not as sweet as the folks who got it for $99 shipped last holiday season but still not a bad deal for a powered 12 inch sub that gets down to 25HZ. Parts Express had it shipped within 24 hours and since I live in the Northwest it took about a week to get here. The box was double packed, which is nice considering the investment and seeing how UPS handles packages. After hooking it up, I followed the LFE instructions and turned up the crossover and gain all the way and turned on the amp. Immediately I was unimpressed. The sub seemed weak and more often than not it just seemed to be taking up space rather than performing any real function. Fortunately I found out that a combination of poor source material (Disney films from the 50s, which have no bass whatsoever), lack of a good break in period (this sub truly sounds totally different after it's broken in ie 20 hours or more of solid use), lack of proper tuning/crossover selection, and a faulty digital coax cable (it was pinched/crimped right next to the plug) all contributed to a completely un-inspired performance. After adjusting all of the aforementioned and swapping out cables, I discovered that this sub is truly a beast that can shake an oversized living room with vaulted ceilings as well as a small house. I tried out Independence Day after making the adjustments and man you could feel every single explosion even with my main receiver at -25dB on the master volume. I also have tested it out for music and the sub is surprisingly accurate for the price and will do a good job of keeping up with fast paced bass drums and sounds fantastic for any bass heavy music. If you are used to the likes of an SVS, Outlaw, etc. then you will likely be unimpressed by this sub (as you should be since you are comparing a Sub at under $150 to $500-$700 subs), but if you are used to the likes of a $200-$300 Polk Audio, etc. then you will be impressed by the Dayton Audio SUB-1200. Not super powerful, but enough to get the job done (and surprisingly accurate for the price) with proper tuning and break in period and it won't break the bank either.

Rated 5 out of 5 by from "BASS" ! ! ! !I've had this a few years now and, have been "very pleased" with the sound quality. Should the time arise when I feel the desire to bring my ceiling down for remodeling purposes, all I will need to do is crank this up to begin the project. Seriously, this is an excellent sub that any true audiophile should have to complete their system.

Dayton Audio SUB-1200 12" 120 Watt Powered Subwoofer

I just replaced a Boston Acoustics XB4 10" 85-watt RMS powered sub with this one. I have to turn the gain on the Sub-1200 up much higher (1 o'clock position) than I did the XB4 to get the same volume out of it...any thoughts?

Asked by: Natron84
The input sensitivities of the amplifiers are probably different which would cause this. You can bump up the output level on the receiver to compensate for it, but its not uncommon for the gain to be around noon or 1 o-clock on a powered subwoofer.

How can I chain 4 of these together to give me the low end power I need to match my old school 2 channel amplifier? I already run 4 12" Stereo speakers & it produces extremely low bass, but I want to crack dry wall in my house with low end power.

Asked by: Pain for Fun 1980
Yes you can chain these together using either the speaker outputs or the line level outputs, depending on what you are using as an input.

I like this sub but am looking for more power than the 120 watts it produces. Does anyone know of a Dayton amp that I could put in this sub without any modifications?

Asked by: BillBill
Unfortunately none of our amplifiers will be a drop in fit for this cabinet.

I have seen several comments about "breaking in" a subwoofer? Why? I have a fair amount of experience with speakers, but not subwoofers. Now that I want a good sub with my big 4K screen and Yamaha amp, I would like some more information please.

Asked by: dale201
"Breaking in" a speaker or subwoofer simply means the suspension of the woofer will loosen up over time. This generally provides a cleaner low end. The break in time is different from speaker to speaker, but playing this with normal music or movies should break it in after a couple weeks.

I recently bought a monoprice sub to add to my maudio AV40. I had all kind of noise coming from the speakers, got worse when I was moving the mouse or a video game was running (gpu activity) and returned it. Would I have the same issue with this?

HI  Have a Sony  str-de598 stereo reciver that would use a monaural audio cable to connect to a subwoofer. Is this compatible? If not can you suggest another product that is?  Thank you

Asked by: Ma Dag
Yes this will work with a single RCA cable for input.
