Rated 2 out of 5 by from Just okI bought this sub 2 weeks ago. I thought I was upgrading from my 10 year old J B L 10 inch sub, but my old sub kicks twice as hard as this one does.

Rated 5 out of 5 by from Powerful and DeepThis subwoofer is outstanding. I did a ton of research and kept hearing about this sub in the AVS forum as the best value for your dollar. I am a budget audiophile with the Pioneer Andrew Jones 5.0 speakers, and purchased this to replace an underpowed HTIB sub I had. This sub has added a new dimension to the sound. It is really deep and doesn't leave those gaps in response that the old 10" HTIB sub did. The system sounds really powerful now and I can't imagine needing to spend anymore if you can get this kind of performance for $110. The only question I have now is if I should get another one of these or the 15" version to really rattle the foundation. This has been a great addition to my new home theater.

Rated 5 out of 5 by from simply awesome!!These things can really rock the house! I bought 2 for a theater system and they are very very clean sounding. I tried them out on an older system using the speaker level input and pushed them. The output is amazing and stays sounding clean right up the limit. The only glitch is when in theater use the auto-on feature doesn't always pick up signal. I just have a RCA split cable to them, and set the gain up a little more. They turn on but not until the volume goes up a bit. The best part is the price!! I dare you to find a sub that can match this for the price, especially when the baby's are on sale (I should have waited a little longer to get mine lol)

Rated 4 out of 5 by from Good sounding Sub Especially for the Price!!!I am surprised how good these sound for the price. I bought 2 of these for $218 shipped. I am using them in a 7.2 setup with a Denon AVR 2312CI with Audyssey MultEQ XT. I used to have 2 Outlaw Audio LFM-1 Plus subs ($998 shipped). The Sub 1200 doesn't have the depth, extension, or power of the LFM-1 Plus, but 2 of these are good in my 20' X 15' X 8' living room. My floors are carpeted and the rubber feet sank into the floor too much only giving a half inch of clearance for the port so I put a 3" square piece of 1" thick high density black packing foam under each foot. This gives the port enough room to breathe and took any boom or mud out of the sub. I am really impressed with these, that says a lot because I really wanted to purchase 2 PSA XS15se's, but for financial reasons it was either the Dayton's or no subs at all. I'm not disappointed at all. In fact my whole 7.2 setup is now all Dayton's, I'm using 7 B652 AIR speakers as well and for a total system cost including receiver of $825 it sounds comparable to my over $2,500 previous setup. The speakers in this setup sound better, but the subs aren't as good.

I want to pair this sub with a Yamaha ATS-1010 sound bar. The sound bar goes from 150 Hz to 20 KHz. Since this sub goes from 25-140 Hz, will I be missing the sounds in the 140-150 Hz range? Also, do I have to set the crossover to 140 on the sub?

Asked by: jhumroo
The "gap" between the sub and satellites will not be noticeable. When you install a system like this, you will have to play with the crossover frequency settings to get it to the point that sounds best to you. I would start with the crossover frequency at about 12 o-clock, and move it up or down while listening to find the best position. It may be lower than you expect.

I have carpet flooring, do I need to put a wood board on the carpet so the sub's port will have enough space to breath? will it have a positive effect on the sub's sound?

Asked by: samfd
Unless the carpet is thicker than normal and really restricts the air flow this will not be a problem. You can experiment with this to see the differences and determine whether it is something that would be worth doing for your application.

On the video we are told to use the R input on the subwoofer and here one of the answers says to use the L input........??????

Asked by: Ike2
The input used makes no difference on this subwoofer. Usually the Left input will be labeled mono, but this isn't always the case.

I have Onkyo SR 606 receive which has single subwoofer out, but this day subwoofer has L and R, so i need a different cable to connect or would connecting to one of them work ? which is a better option?

Asked by: lapchaser
You will only need to use one of the inputs on the subwoofer, an adapter cable is not required. Usually the Left input (white) is used for a mono input.

1. i had a boston acoustics mcs130 home theatre system in which the subwoofer died. I wanted to replace it and came across this. specs of the subwoofer from mcs 130 are 10” (254mm) DCD ,40 - 150Hz i want to know if this is a good replacement?

Asked by: lapchaser
This would be considered an upgrade to the original as long as the receiver in the system has a single subwoofer pre-out. This Dayton subwoofer does not provide power to the other speakers in the system, it will only power itself.
