If the Leslie amp's output impedance is 16 ohm (and all the early ones
were), an 8-ohm speaker could result in distortion, loss of bass response,
and could damage the amp as well. You definitely want to get a 16-ohm
speaker in there--your amp is at risk until you do.

These comments apply to Leslies with vacuum tube amps--the later solid state
Leslies used 4-ohm speakers, I believe--at least some of them did.

I had a 15" Utah speaker that I used with a bass amp in the 60's--worked
pretty well, too--with a 30-watt tube amp that I built myself from
components bought at the Lafayette Radio store in Boston. Bought that
speaker from Allied Radio for $18.00 in 1967, and it was listed as a
replacement speaker for bass and organ.

I believe Pyle is a reincarnation of the old Utah speaker company. All of
the original Leslie bass speakers were Jensen's to my knowledge.

The Pyle may or may not be a bad speaker. The Jensens were in there largely
because they were inexpensive. That is why Leo Fender bought them for his
amps as well. The Jensen's were not a high quality speaker, and in fact a
high quality speaker can make a Hammond sound worse. This is more true for
the treble driver than the bass, however.

One thing to check on the Pyle is the impedance. The Jensen's were 16 ohms.
If the Pyle is an 8 ohm speaker then you have an impendance mismatch, and it
will impact the sound. An engineer (which I am not) will have to provide
more specifics on impedance, but I do know that Leslie speakers are 16 ohms.

Hope that helps a litte and that the information is accurate (which I am not
100% sure of).
