[Allison IC-20'S (in original boxes for 20 years!)]

It was and I tried to get Roy to change it as most consumers at the time including myself had an 8 ohm receiver abd weren’t willing to upgrade and some people blew up their receiver running the Allison’s on it. He didn’t want to give up the sound quality.

The black and white image of Bob Ricci brings back memories. I worked at Allison for many years. Great product. Thought he should have gone to an 8ohm unit.

Bill,

"Another thing: the treble dispersion on the IC20 is so outstanding that the integrated acoustic-power output is better than almost any other speaker, and therefore the high-frequency output into the reverberant field would more than offset the slight attenuation that might be occurring at the frequency extremes! Yeah, perhaps that last half-octave in the 15-20 kHz region is down a bit on axis, but the power response is probably ruler-flat out to at least 15 kHz, so what's not to like about that! There are any number of exotic speakers with great "imaging" and ruler-flat on-axis frequency response in the direct field that would fall flat (no pun intended) trying to put energy into the reverberant field. Poor off-axis performance assures that a directional speaker that sounds "spacious" and "3-dimensional" in the direct field, toed-in pointing to the listener a few feet away, will almost always sound dull and lifeless once that listener moves back into the room's reverberant field. It is amazing how much poor dispersion affects the overall performance of a speaker! Some speaker companies think that they can use a directional (read: "large-diameter") midrange driver and a small-diameter dome tweeter and solve the dispersion problem, but this isn't true. Much of the power response energy is in the midrange and lower treble."

Beautifully stated, Tom, and covers most of why I've been a fan of the A1, which shares most of this in addition to the IC.

Oh yeah, I will tell it again here (added to my original post)

From my first introduction to the IC from RA himself in 87 or 88?

To my rental truck in 2012!

In a few days.....
