[Geoff St. Germain]

I'm all for bass overkill, but I'm not sure I get the point. What are your mains? The two bass towers you have now are capable of about what... 126 dB @ 1m at 10 Hz and over 130 dB @ 1m at 20 Hz? And that's not factoring in any room gain. Can the mains compete with this? If it were me I'd look at spending some of that ~$5K on upgrading the mains if volume is a problem.
