You don't need 44mm of xmax or even 38mm xmax to get me interested, as we already discussed, those ideas are just too impractical, even in large ported enclosures, it can be hard to use that much excursion, as you know, you need 4x the power to get the driver to do twice the excursion. I'd be psyched about an 18 with ~30mm xmax. It would be real nice to have a lower qts, that way we could 6-7 cubes sealed and yield a critically damped box, unlike our current high excursion 18" offerings. Your right, super tiny enclosures for PR
's don't make sense either, too much mass is required and its too hard on the PR
's. But I would love it if we could do 8 cubes or so tuned to ~15Hz with a pair of 18" PR
's. A hp filter would be in order, but as I see it, there is just no need to do insane excursion due to the how prohibitive it can be, requiring beefier PR
's, more power, higher cost ect. What would be nice is a target price right around $650 or so, kinda like an 18" tumult. That way you wouldn't price yourself outside of the market and could still generate enough demand to keep costs down and profits up a bit. If it can't be done, hey it can't be done, thats fine, its just what I think would revolutionize the diy market.
