Dayton Audio SUB-1200 12" 120 Watt Powered Subwoofer is rated 4.6949 out of 5 by 118.
Rated 5 out of 5 by from Fantastic SubwooferMy initial impression was slightly scary. PartsExpress.com puts exactly what's inside the box on the outside of the box for the world to see. The UPS man left it in my driveway. Luckily, I live in a good neighborhood. Seriously, PartsExpress, you need to fix that. Wow.I picked up the box and dragged it inside with excitement. It was finally here! This is my first real audio purchase in many many years and my first real home subwoofer purchase. The box was very well packaged and surprisingly light. I saw no deformations or issues that stuck out.Un-boxing was simple. Exterior box. Interior box. Plastic wrap. Those are the only layers that separated me from my lovely new speaker. It was somewhere near this point I realized, "Whoa. That's kind of large." Again, everything was very well packaged as all the other reviews point out.I plucked the speaker from it's cardboard womb and placed it on the carpet. I had a moment of panic when I couldn't find any cords. PartsExpress hides it in the bottom port. Man this thing is solid! (Getting very excited at this point)Setup was easy. I had to use an old and worn out pair of speakers in the interim and run wires through the high-pass until the rest of my equipment arrives next week. Essentially, I made a few cables and turned some knobs. I had sub-frequencies. Oohh Ahhh. Wow. That's....kind of loud.The bookshelf speakers I am currently using are just down right bad. They make my ears bleed. I just couldn't make this sub sound good with them unless I turned it nearly all the way down. There's a huge gap in low/mid frequencies even with the crossover turned all the way up. It was a frustrating experience but I was happy to have the first real piece in place.The Dayton SUB-1200 sounds very good. Note that I didn't say, "for the price." I said, it sounds very good. There's heaps of sub-sonic frequency, plenty of grunt, and a very smooth sound to it. I grew up in car audio and hate boomy loud subwoofers with a passion. The controls are easy to understand and use. The bottom firing port goes unnoticed. The construction is of the utmost quality but still basic to keep costs down.Note: Obviously I'm just starting to break this driver in. I don't expect to see full results for ~10 hours of use. I also wont go over half gain until then.I tried a few movies and a few songs; Star Trek: Into Darkness, The Avengers, Debussy - Clair de Lune, Deadmau5 - Ghosts 'n' Stuff. Right here is where I stopped. I started to hear glasses rattling in the kitchen and realized it was 9:00PM. It was the only good part of watching the movies and brought another dimension to the music. I've read more than a couple reviews on this speaker and they just don't do it justice. You really need to audition something like this in person. It's a visceral experience. One that can't help but leave a huge smile on your face.The Dayton SUB-1200 is fantastic and beyond excellent for the price paid. I purchased this unit on sale for $119 and paid $14.95 to ship to TN.

Rated 5 out of 5 by from Amazing price to quality ratio!I've had this sub for about two weeks now and I couldn't be happier with it. I paired this up with some Micca MB42X bookshelf speakers (amplified by Dayton DTA 120) and my music now sounds complete. Bass is tight, punchy, and really rumbles my house although its likely because of the wood floor. The overall presentation of the sub is very appealing, the knobs spin very smoothly, the removeable woofer cover. I have not tested it to see how it performs with movie audio but I'm pretty sure it would not disappoint. Extremely happy with this purchase :D

Rated 5 out of 5 by from Amazing at this price point!At this price you cannot go wrong with this sub. I haven't dialed it in yet, but at half gain I had to turn it down as it took over my newly finished basement project. I have this sub working with a yamaha 475 receiver and Pioneer Andrew Jones bookshelfs and center. Couldn't believe how low this sub gets and how clear it sounds. Simply amazing. I'm thinking of replacing my 20 yr mission sub in main living room with one of these. A+++ Dayton!!!

Rated 5 out of 5 by from Bought two of these for Onkyo Sub that went outThey are great. Work well together. Took the mono connection and split it for the extra DB's. Worked great had a little time invested to tune them but it was pretty easy. The bass with music is great and with movies it shakes the furniture on my 7.1 Onkyo system. I can say If I only eould have bought 1 sub it would not have been enough after reading other reviews. But for the price and shipping I am 100% HAPPY. Great overall product.

Rated 5 out of 5 by from Best BOOM for the buckI ordered this woofer after careful research for a pc speaker system with a good value, only the night after the money cleared through the bank the woofer arrived at me house and sound EXCELLENT. I could not have asked for anymore.

Rated 5 out of 5 by from Also LoudI converted the in-laws from big floor-standing speakers to in-wall speakers and a sub on a small budget. The SUB-1200 does the job for their karaoke setup; they seemed pleased with it. I've personally used the older-model SUB-120 for a few years and I think that these are great subs for the price.

What is the ohms for the woofer ?

Asked by: mikeylok13
The woofers in these subs are all 4 ohm. Since they are self powered this will not affect the load the amplifier sees.

Teaming this up with lepai lp7498e & BIC DV62si...is it better to y-split source, running RCAs to both amp and sub or run from lepai speaker outputs & then to main speakers?

Asked by: ssornaes
I would recommend using the speaker level ins and outs from the subwoofer instead of splitting the source.

I have an Onkyo receiver and it only has a subwoofer output. Not the dual RCA's for an input. I was thinking about purchasing one of these maybe two and just using an RCA  Y inorder to use both channels for Max DB. Do you think this will work?   

Asked by: JMBLOWNWS6
Yes you can use a Y adapter for this, or just use one of the two inputs on the back of the subwoofer amplifier.

just wondering what cross over frequency should I set on the receiver...  Currently I just set to 120hz and turn the sub-1200 cross Freq to max ... using the LFE input. thanks

Asked by: dragon968
The crossover frequency is up to you. You want to use a frequency that will allow the main speakers to blend well with the subwoofer, but not be too low for the speakers to handle. Using the receiver crossover is a good way to do this so you know you are getting a similar crossover point between both.

I have a pair of klipsch RF-82 speakers and wonder if this is to much for them?Should I go with a 10 inch instead?

Asked by: videoluvr
A 12" will be fine and give you a bit of added headroom. You can always turn the volume down if you need to.
