Purchased this at Best Buy for around a $100 some years back during a sale. In my 15x20x10 bedroom, the sub is deep and thunderous. Very good for movies, you definitely feel the low bass notes quite well. However, for music it's not suitable for those with discerning ears.

Build quality is great. The all-black color is very simple and easy to match with other components. However, the back part which houses the connections, volume control, crossover, and line in, feels very flimsy in its plastic. No problems with that so far. The "feet" of the sub are non-existent and the unit can be easily pushed around like it does on my hardwood floors.

For the money, if you're on a tight budget yet want a step above cheap HTiB systems, this subwoofer along with the rest of Sony's value speakers will fit perfectly. I use this as a second sub in 5.1 setup by JBL's now-discontinued Venue Series.
