Thoughts? I was also looking at some Elemental Design subs as well but it's hard to beat dual 15" subs in 1 enclosure.

# Reference dual 15 inch high output subwoofer
# Exclusive 600W RMS amplifier
# 1500W short-term RMS
# Frequency response : 20-300 Hz +/-3.5 dB anechoic
# True 15 Hz or lower in-room extension
# Weight: 140 pounds shipped

 

i have no experience, but i keep reading the SVSound subwoofer is really nice.
