Subject:Re: Driver search

Selenium makes many different drivers; some of them are suited towards a
Leslie, others not.

I did a ton of research on high-power Leslies many years ago, and
settled on the D405i with the phenolic diaphragm -- *not* the titanium
version.  It sounds just about *exactly* like the V21, and rolls off
smoothly at about 6kHz.  The only problem is,  it's both huge and
heavy.  But it's just about impossible to burn up (it will handle more
than 200WRMS of 800Hz+)!

That said, if you find it "boring," then perhaps what you are looking
for is the sound of the V21 on its last legs.  (Think: Steppenwolf,
Spencer Davis Band).  The V21 was chosen with '40s/50s organ tastes in
mind, and thus was designed to handle the *clean* output of a Leslie. 
It's only rated at about 18-20W, though, and an overdriven 122/147 can
easily put out 25-30W of distorted high notes.  In that case, the V21
will provide a lovely, sizzling tone -- for a few minutes to a few
months.  Then it will likely fry.  Not a great long-term strategy.

Three drivers that I have personally used that sound like a V21, but
take more power:

* Atlas SA-1232
* Electro-Voice 1829 (not 100% sure about the number; might be an
1859; the driver looked like a big gear)
* Selenium D401i

The first two have been out of production for ages.  The third one might
be, too:  the last one I bought was in 2002 or 2003.  As Goff mentioned,
the H-S ferro driver can get close with a resistor added across the
input terminals.  There are probably others, too, but I don't have
experience with them.  (The D401i sounded so good, and was so
bullet-proof, that I stopped looking and started worrying about how to
mount the beast!)
