Legacy audio Focus XDs, dual 12 inch subs with active 700w per channel, my house and walls rattle, shake and boom like never before, especially with electronic music. Absolutely the best sounding and most realistic sound pressure level speakers for the money of any speaker I have heard.
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?
