This is good news…… And I wanted to wait until it was over before I said anything!
Unless there was a height issue in your listening space, you would’ve had plenty of room…… you only need a couple of inches in width and depth to accommodate the IC 20s, that would just take over your original footprint. If you were adding them to your collection, that would be another story, of course.
Well, you certainly have me outnumbered with a quantity of spare drivers according to what you wrote. Anyone who was interested in the IC 20s REALLY needs to have a stash like that to be committed for the long-haul.
Interesting what you said about the output….i’ve never done that extensive testing of the drivers; only whether they work or not and whether the mid range drivers have any of the infamous voice coil rubbing that can happen with those.
Before Bill Legall stop servicing Allison out in Lansdale PA, he rebuilt a few of my IC 20 drivers…..the midranges that exhibited some of the voice coil rubbing and realigned the voice coils, using a signal generator.
Curious if you tested the driver output out of the cabinet? There are several factors that could impact the individual DB output of the drivers if they were to be tested inside the cabinets.
The Allison:One is a magnificent loudspeaker. The only reason I had for going to the IC 20 was that the opportunity presented itself but if it had not, I would’ve been sitting pretty just the same.
I ran the A1’s in a surround-sound configuration for 12 years before I swapped them out for the IC 20s and it was magnificent
