As I read through the responses the talk turned to only what the bass could or was doing and nothing about the overall sound quality of the speaker. With that in mind I will put up my old Bose 901’s running through my Sansui 7070 receiver. I was able to knock trinkets off the shelf of my neighbors home. Take sound quality out of the mix they are the best party speaker made.
Speakers with deep/powerful bass
I used to have a system with large speakers. Each speaker had two 12" woofers. When I would play Hard as a Rock from the AC-DC BallBreaker CD there was a moment at 35 seconds into the song when it felt like someone was jumping on the floor behind me. This would only happen if my JPS Labs Golden Flutes were looped into the system, and it was playing very loud. Without the Golden Flutes it didn't happen. It was a truly frightening experience the first time it happened, because I was home alone. Has anyone else had anything like this occur?
