    Thanks for your comments! You've got me thinking. First of all, I should admit that I've always assumed that both the 1400ND and the 1401ND are 8-ohm drivers.

    One thing I've wondered about is that...

    The main thing is that I don't consider that the crossover and EQ for M2/4367 "hybrids" are fully optimized—yet. The 2216Nd-1 is a significantly different woofer than the 2216Nd used in the real M2,...

    JBL DMS-1 or very close?

    It was three or four years before the introduction of the M2 that I saw a pair of 2450SL drivers on 2332 horns in an eBay listing and thought, "That could be the start of a DMS-1 build." Now, years...

    Bit of an ancient history question, but does anyone know what, if any, differences there are between the DSC 260 and DSC 260A speaker processors?

    And are they by chance just rebranded dbx...

    I believe it was 2" thick panels. (Augspurger had recommended 2" of the regular pink fibreglass, but on all interior surfaces except the front baffle.)

    JBL DMS-1 cabinet info?

    I'd be most grateful if any owner of the JBL DMS-1 monitor could help me out with some information about the original factory cabinet.

    I'm working on a DIY version of the DMS-1.

    A very tardy response to this thread, but something that's been on my mind lately.

    The crossover, passive or active, is very close in importance to the speaker drive units themselves.

    And, once...

    If by "time correction," you mean delay, there isn't any applied, according to JBL's "Settings" document for the DMS-1, concerning which see the earlier...

    I noticed quite a few JBL 2217HPL on eBay lately with very modest asking prices.

    Some comments I've read on these forums, while not definitive statements, do suggest it may be possible to recone...
