Thanks for all the help. So I am looking at a set of MR94A's with 291 series drivers..I understand you can replace the Symbiotic diaphram with an aluminum type found in the 288, essentially for all intents and purposes this makes the 291 into a 288...The other issue would be what the best match in OHM rating on the diapram would be with flea powered single ended pentode 6BQ5 tubes?
Well, what output taps are available on the tube amps? 8 and 16? If so, you can use either. If only one, better consult the person who built the amps.
I always wanted to try the large format stuff. Perhaps I'll start keeping my eyes open. I'd like to try the 299-8A tangerines on the big Manta 40x90 horns.
FWIW.....my room is dead....love it that way.

Watch the throat on those MRII564s, the weight from the driver can snap the fibreglass.
Just me being superstitious, but the 16 will use the entire secondary and the 8 only half, as it is a tap. YMMV.Originally Posted by RonSSS
