Xandcg, these bass compression drivers is a controversial
subject. T think there are 3 of them ALE 160 and P1260
and GOTO SG-146LD. I think they all 4”, it would be very nice if they were 6”.
However, 6” exit might be a bit too wide for compression type diaphragms. Anyhow, as I said it is those drivers are debatable.
We kind of accustomed that in compression drivers the intrinsic sonic quality
of compression drivers is very much observable. However, with midbass channel
it is more complicated. If with MF channel you make a proper horn then good 50-60%
of sound is the sound of compression driver itself. With midbass the total
sound of channel is about 20% come from the driver and the rest comes from the
horn design, channels integration methods, room integration methods and a few
other factors. So, in my view the bass compression drivers mostly a cause of
problem then a solution and I would be very watchful to employ them.>>
