I didn't notice this post previously, but it came up while doing a search for some other information about this very review. First, there has been some discussion about the nature of the the measurements taken as part of that review (see this AVS thread ). Second, the sub being reviewed is the LFM-1 EX, Outlaw's biggest sub. The original LFM-1 (the one that I have and reviewed here ) is no longer in production, and there are several other Outlaw subs still available (the LFM-1 Plus, LFM-1 Compact, and LFM-2). Third, I would typically recommend letting your surround receiver handle the bass management (bypassing the sub's crossover) as it is the more flexible technique. And for what it is worth, your main speakers sound like they'd probably have a low frequency extension at least on par with my Studio/60's, and I've had no problem integrating my old LFM-1 with them using crossover points of both 60Hz and 80Hz (with the surround processor doing the bass management and the sub's crossover bypassed).
