Rated 5 out of 5 by from Excellent ValueI never review anything but this sub is worth it's weight in gold. For the price, you cannot go wrong. I'm using it on a small 3.1 system for the living room TV and it sounds fantastic. Very pleased with the product and parts-express shipping was fast.

Rated 3 out of 5 by from Okay if you only have room for a small sub.Don't expect to drive this very hard, you can easily cause this sub to distort. I have the 12" and although I did not expect it to perform as well, I am disapointed.

Rated 5 out of 5 by from perfect additionBought to boost the bass for my Jamo 2.5 in. satellite speakers. Great sound!

Rated 5 out of 5 by from great in combination with the audiosource amp 100This amplified sub is used in combination with an audiosource amp 100, a xantec bdx tt bluetooth receiver, and definitive technology 350 speakers. The audiosource amp has a pass through output which is perfect for an amplified subwoofer. In this set up the subwoofer is set for an 80 hz crossover and volume knob at 12 o'clock. This combination provides a very smooth frequency response from 40 to 15k hz. that is very musical as judged by youtube high definition video content ( such as pink floyd's official content "Marooned" ). The dayton 10" will provide musical tones down to 35 hz in this system. The bluetooth receiver no doubt limits the extreme frequencies but it is a matter of convenience over absolute performance.

How do I know if the phase switch should be on 0 or 180 ?

Asked by: 2cycleman
This will be selected based on listening tests and subwoofer positioning in the room. In most cases the switch will need to be on 0, but you can try it in both positions to see which blends better with the rest of the system.

Is this 80w into 8ohm or 4ohm.

Asked by: fsdaron
The power output is 80 watts RMS into the 4 ohm woofer, but this makes no difference to the rest of the system.

I want to plug this into my computer does it require a receiver or can I just connect it through my sound card?

Asked by: Dave829
This can be plugged directly into the sound card although it will only product bass and will not power any other speakers. The best way to do this is to use a small stereo amplifier plugged into the speaker level inputs and outputs.

Is it possible to run outputs from DTA-2 Amplifier module to high-level inputs on this sub in parallel with output from amp going directly to speakers (not using high-level output of sub). Will this drain more power from the amp?

Asked by: finndersen
Yes this will work fine, it would be no different than using the speaker level inputs and outputs together. There will not be more of a load on the amplifier.

I would like to run a stereo pair of the sub-800's.  They will be connected to my pre amplifier.  Will this sub accommodate this configuration?  The preamplifer does not have a sub output.

Asked by: Don13
Yes this will work fine, you will simply have to run the left preamp out into the left sub and right output into the right sub.

This appears to be front-firing from the pictures but the description says down-firing. Can anyone confirm? Thanks..

Asked by: howard13123
These subwoofers are front firing with down firing ports.
