Price Paid:  $100.00 from RAON

Summary:
I've been hunting for a good HT sub with a good price/performance ratio. And i think i found one that suits my need. I like the forward-firing design and it got lots of knobs to tweak like crossover cutoff, eq, subwoofer volume . There is a ls also a phase switch 0 to 180 degrees so that you can fine tune your subwoofer.
Overall build quality is very good, from the surface finish and the paint quality.
It weighs approx 18 kilos. Sound quality is very good considering the price you paid for the sub. I could've got a velodyne sub but budget restricts me to do so.
after tweaking the sub's knobs, switches and it's placement.. You'll almost forget that you only paid $100 for this item..

Strengths:
what I like most about this sub is that it automatically turns off if there's no signal detected the reciever which can conserve electricity in the long run.
Lots of knobs to tweak that can fine tune your listening desire.
Build quality is perfect.. the paint finish and the color of the sub compliments very well with my other speakers.

Weaknesses:
The only thing that i noticed with this sub is its not really good for music listening.
There are times that I want more bass on the music I listen to so what I just do is turn down the sub's volume just one notch and all is good. But for crucial music listening I usually turn off the sub. Anyway this is an HT Sub so its just understandable.

Price Paid:  $110.00 from Spectra Audio Video

Summary:
The lows are subterranean and can deliver powerful sound, although I wish there was more punch (tightness) in the higher end of its bass spectrum. However, I derive some satisfaction listening to my dvd's i bought abroad and try to be content for the moment. What can one expect from a sub worth only a little over $110?

Strengths:
Can deliver lows that seem to creep below the floor and I like the feeling. The architecture of the box and the color suits my taste.

Weaknesses:
Should have come with a remote so one does not have to go around the box to make adjustments. At night, when all is quiet, one can hear ac hum and, even when the volume control is set to zero, there is audible sound accompanied by very visible excursions of the cone. Also, when the volume is increased, the boominess likewise increases. Pardon me, but can anyone explain why? I had a home-made box (transmission line type, Bailey's design) with a pioneer subwoofer and a filter designed for a subwoofer. I plug it in to a locally made amplifer-booster. When it delivers the lows (really very low lows), I get the sense of being pushed from under my bed. Why don't I get this from the dq-12?
