I'm not saying it's available, it's just a superbly detailed build thread of conception, design, construction, implementation, and optimization of a pair of small-sealed, dual opposed. Anyone contemplating such an approach would be well served to read it.
I'm not up on what's available these days, seems products come and go. The Titanic always seems to be there, the aforementioned 15" LMS, also, I'd examine Fi's offerings, enormous bang for the buck,...IMO. Displacement would be key, tons of it in multiples (stay away from the excursion limits, spread the signal across multiple VC's, limiting compression effects),... then optimize the subsequent install with measured results at the LP, ... and you're there.
