here a interesting comment of RCA MI-1443 used in the midbass range above 250hz. Since this is a hard to get, and expensive driver, is there a interesting alternative , worth a try, to replace Fane Studio 8M ?

Visited CV tonight and we listened to the Azura 160s with both S2 and RCA MI-1443. S2 crossed at about 300Hz and RCA at about 250, I think. Ok, it was one mono channel, with just the horn and a Fostex tweeter (the expensive one with magnesium diaphragm).
What we listened to was rather rough and ready, but has reinforced by conviction that using a compression driver down to 300Hz, or even 200Hz is absolutely desirable. The 300Hz - 1kHz contains so much fundamental musical information, thaty getting this right is extremely important to reproducing music.
The S2 is nice and it's definitely works using it down low like that, but may not be the best choice. In isolation it sounded very good used like that. The RCA on the other hand is a completely different kettle of fish. Absolutely astonishing. I don't think I have heard Cello reproduced in such a lifelike manner. Piano is notoriously hard to reproduce with realistic scale and presence. Truly, despite the limitations of the thrown togtherness, this showed such promise that you soon realise that conventional speakers are never going to compete.
JJ - this has convinced me it's defnitely worthwhile going down the compression driver/big lower mid horn.
