Pros: Serious low end bass that you can feel
I had a Onkyo HT990 HITB. I started upgrading my system to BIC America's Acoustech series. The first speaker that I changed out was the sub. I can now tell you from personal experience, that I never thought a great sounding sub would make that big of a difference! Man was I wrong. I was so impressed with the performance, I bought another one.
