Summary:
I just upgraded my components for my little home theatre.

Onkyo Tx-ds777
Pioneer DVL-919
JBL HLS 610 front speakers
Timbre TTS-2 Surround speakers
JBL center speaker.

I'm stilll trying to get the best result (balance) from the speakers, but the pioneer sub really give plenty of deep bass. Especially the bass is so weak from the Onkyo. I hope after some burn in of my speakers (all less than 2 months, except the center which I also need an upgrade, you guys have any suggestions? Need JBL). If you experts have any commends or suggestions, please feel free to e-mail me.

Strengths:
Powerful, build quality, good price.

Weaknesses:
Take some time to get a well balance of the spectrum.

Summary:
Really tight bass on the first floor, even better on the second, but really bad in the basment, boomy and little bass output....

But otherwise, this thing POUNDS.
You know this thing has 200watts RMS

Erykah Badu's On and On is really something to be heard, over and over again.

If you're a basshead, this is the sub to get many of, unless you got the cash for a Carver Sunfire :)

Strengths:
Smoothness, Impact

Weaknesses:
Slightly boomy at times

Similar Products Used:
Sony 6.5 inch powered sub, nothing much to compare :)

Summary:
This subwoofer kicks ass literally. We have it behind the couch and when action is being played out on the TV from the DVD player the couch moves like crazy and you feel the bass in your chest. You actually feel like you are a part of the movie.
