I have recently purchased two jbl 12" drivers (LE120H-1) that I believe are used in the L90 (and maybe L7). I bought these because they supposedly work well in a smallish cabinet. I have some tentative T/S parameters, but what I would really like are the cabinet and port dimensions of the L90. That way I can start by duplicating the cabs and the port tuning. I know the L90 has internals, but with heavy internal bracing I think it would amount to about the same volume.

Are there any L90 owners out there? If not, I think the L7 should work.
