I feel for people who appricate good strong but clean bass that dont want to have the space conficts of a 10 or 12 etc, 8's are the way to go, the L7, Crystal Comp8, Tang Bad, and Re 8, dominate the market from what I have seen but they are all a little different in direction, some are dedicated subs some are more directed at mid-bass in its design, heck some people are doing walls or extensive 8" installs due to being able to fit more subs in a smaller space, Lyod is running the 18 RE8s and James on CA is running 8 RE8s etc. so I think it is a seciton of the market that is just starting to get attention, and if you can build a "super 8" in the 45-70 price range it will really boost the market share for sound splinter, I believe stereo integrity is thinking about one also, I personally in the market for a single 8 that is resonably priced for a present for friends, I bought a bunch of RE8s last year for a few people, but they are DVC4 or SVC2 and I need to track down an 8" of SVC4 or DVC2 so that a few friends could run it in a single sub set up with a small amp for a nice SQ set up, the more I read about the Crystal the more it turns out to be like a mid-bass, and the L7 is more than I want to spend, so as you can see there is a demand for a sub that you could build
