Summary: This is a very good subwoofer. The front firing design is the best in my opinion. You hear the bass without shaking the whole house unlike the bottom firing designs. Like many of the other reviews, I started having issues with the volume and distortion after about 18 months.
Summary: I bought it for our new addition of a 14' x 16' room. I was looking at the 250 and thinking bigger would be better. I was wrong again. I'm running this with two 530BK's and this sub does the job well.
Excerpt: This sub is a definite improvement over my previous Orbit sub. The system now has a much fuller sound overall. Unfortunately, it points out the weaknesses in the rest of my sound/theater system.
Summary: It's a bit much for my little place but it really brings the tv and xbox1 to life. There's nothing like having a full range of sound. The unit looks great and is quite heavy (to be expected). Great great value, it really pumps out some nice clean bass. I don't regret this purchase at all.
