It was even funnier than that actually…… The audiologist puts me in this tiny booth for the test. She was very nice and very pregnant. I have to say seven or eight months at least. So here I am in this midget booth with this woman who is getting ready to deliver trying to crawl around me and hook up her wires and microphones. The whole thing was morphing into something straight out of a sitcom. so the “three” of us got it done. I hope the kid is doing just fine.

The last time I was checked by an audiologist, I kept putting my hand up… Whether I heard something or not she wasn’t very impressed.

Not sure about this…… I totally get the difference between a wooden speaker enclosure versus an acoustic suspension enclosure. Somehow, the whole nostalgia thing to me just doesn’t fit.

What constitutes a “modern” loudspeaker? If you break down the anatomy of the mechanics typically found in today’s full range. Loudspeakers AR is pretty much as modern as any of them.

I need to be honest and correct myself regarding the Allison top firing woofers…… I’ve mentioned it more than once over the years, but the only Allison designs I’ve never been a fan of, are any of the top firing woofer designs, which include the Allison 4, the 6 and any of those designs which put themselves at the receiving end of dirt. I get WHY they are designed the way they are, but for my money they need to belong to somebody else.

Agreed and you should be good to go. The midrange and tweeters are interchangeable with the other original three-way Allison’s one, 3 eight and nine (if you decide to do a little spare driver shopping)

I had the big brother A1 for 35 years. If you go for it, make sure the 8 inch woofers are original. They should be 16 ohm drivers parallel wired.

I grew up starting in 1963 with the 2a then later, the 4ax and the 2ax. So that being said, I’ve got a soft spot in my heart for any and every effort to keep those old things going. even though I migrated to Allison acoustics I’m not one of those who attempts to restore the actual drivers, but instead made a career out of eBay shopping to enhance my emergency stash.

MDX-2 is the way to go for external fusing. …..Still have some will post a pic later. Great choice protection for the original AR lineup.

All the tweeters in my system are protected by self resetting “by stable resistors“. They open if things get too hot and then come back when things cool off. I had only one that I can recall over the years doing its job. These are Allison tweeters not AR Roy Allison worked for AR, and was the design way back when.

Yes, and not only that my concerns were with the top firing woofer being too far out from the wall…… A compromise to get everything else lined up.

The center channel I always wanted to try (and never got around to It) was on a singular, original version of the “Allison Eight”….(not the “CD Eight”.) That’s the one (if you’re familiar with) the top firing woofer and mid range and tweeter, one of each facing outward in the center of the cabinet.

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

…..No longer available according to the site…. would be interesting to know what happened, but on eBay no available information… So it goes
