Rated 5 out of 5 by from Bass boxI bought this sub a week ago and I tell you for the low price I had my thoughts I just knew this thing was not going to perform but boy was I wrong, this is a excellent sub and the sound quality is just that pure quality very well built it rattles the pictures on my walls and rattles the windows and thats at half the volume level in a medium sized room, very solid and strong sounding sub, I think my friend said it best when he said it sounds like a elephant stumping on the floor, well I have two elephants stumping on the floor now because I purchased another one and have them wired together and it sounds great. Great product Dayton.

Rated 4 out of 5 by from Giant sub for giant roomWorks as expected. I didn't know how low 30hz is but when i watched inception i had to turn the crossover pretty high, probably 100 to 120 to hear anything from it. the sound was pretty good, i'm not an audiophile so i can't give you exact details as to the quality of the sub. This sub is bigger than i thought

Rated 5 out of 5 by from Nothing better for the price!After exploring my options with building my own subwoofer, I found I was planning a subwoofer nearly identical in specifications to this one. To save myself the hassle (and money), I purchased this instead. Parts Express brought me the unit quickly for cheap, no complaints there.Pros:- The connections on the back are perfect for my needs, as I am connecting the sub to a pair of powered studio monitors.- The sound is incredible - it can make the whole house shake when I want, but still plays with a more subtle approach most of the time.- Can't beat $130 for a powered sub at this size.Cons:- You should know this just from reading the specifications, but it's a really hefty unit - about 45 pounds and a foot and a half square. Just plan ahead where you're going to put it so it doesn't catch you by surprise.Overall 5/5, can't beat that price/performance ratio.

Rated 5 out of 5 by from SurprisingPleasingly articulate. I was worried that it would just be "boomy" but it's not. I also have not had problems (yet) with the auto on feature. Running on a Denon receiver with Audyssey setup and recommended Gain set at 50%Overall very happy

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.

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:
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.

Would you recommend connecting the subwoofer to the switched ac outlet of the receiver?  Mine is rated at 1A.  This would keep the power on while the receiver is on.

Asked by: miamoose
I would not recommend plugging the subwoofer into the switched outlet if it is only rated for 1A.

I've noticed several comments about the auto-on not coming on at low volumes, and I have the SUB 800, which has the same issue. Is there a fix for this?

This would be a component in the first speaker setup I have bought so I am curious what kind of receiver I would need to purchase to work with this sub and 2 satellites? Due to being in college, I am on a tight budget...

Asked by: barcode
Since this subwoofer has speaker level and line level inputs and outputs it will work with just about any stereo amplifier. We do have a receiver available that has a dedicated subwoofer output, you can see it below.http://www.parts-express.com/sherwood-rx-4503-stereo-receiver--252-228

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.
