DIY M19 idea's

[bfish]

Hmm, IIRC the only difference between the two expansions is that the 594 is a truncated 994 to create a larger throat same as the 511E Vs 511B, so from the front you're not likely to notice which it is.

Yep. The MRII594/MR994 share HxW dimensions, and only 7/10" difference in length.

Once you slip a 994 in an ~M19 sized box and add the requisite shaping filter, you begin to notice it's more like an M500/9815/A-15 than an M19 (which isn't a bad thing at all). Then you get to longing for the extra ~octave a 3154 can get you, and you abandon the M19 altogether and build some modified M500s/9815s/A-15s.

All can be done with new GPA components too, save for the MR994...

Yep, then all you need is a second 3154 in the M19's net Vb to get a SET friendly sensitivity.
