Saw some sweet Allison ‘s for sale. Looked like Bose 901’s?

Dabutcher

Antique store was asking 600 with chrome Bose stands. Peace. D

Nothing like Bose 901s although, in fairness to both Dr. Bose and Mr. Allison, both loudspeakers were designed to work their best in real-world environments (i.e., in real rooms in real dwellings).

The Allison Four was the - heh - fourth model down the line of the original Allisons, and was/is a pretty darned good 'bookshelf' loudspeaker.

I like the Allisons a lot. Roy Allison was, of course, an AR alum, and lived a good long life (he died last year, or maybe 2016, too lazy to double check, sorry) and had several companies of his own when it was all said and done. Allison Acoustics (from which the Four derives) was his first post-AR venture (AFAIK).

More Allison info at www.classicspeakerpages.net (and/or its forums).

I'd opine that if one likes the early "Monitor Series" Polks, one'll love the Allisons. I certainly do.

There was a time (late 1960s/early 1970s) that it seemed like everybody -- well, at least everybody in New England -- was building a loudspeaker that was at least evocative of the 901. At least in some respects (e.g., sometimes bass-ackwards relative to the 901 ethos, and rarely if ever with FR drivers, other than the 901 itself).

To wit:

It's like all of these guys worked for one another at one time or another

I'll still take my Series II Continentals

those are elegant

The Allison Fours were some of my favorite bookshelf speakers in the early '80s. The only thing to watch for is the plastic grills will be so brittle by now that even removing them carefully may destroy them and they are not available anywhere. The same issue ran throughout the whole line. The Allison Model 1s were great too, but required a setup much like the SDA line with hard surfaces nearby causing lots of reflections with the triangle shape.

mhardy6647

re: the grilles. Yup.
There are reports of "reinforcing" the oh-so-brittle grilles (which, I think, are made of ABS plastic), if one is fortunate enough to be able to remove one's grilles intact.

Here's one:

AR [LST]

I had a pair of those AR/LST’s. Truly great speakers. Had them paired with S.A.E. Mark amp and preamp. One of my big regrets is that I traded them in during about 1981. Now unobtanium.

mhardy6647

Yes, they (the AR-LSTs) were something, indeed. Notoriously hard to drive/picky of amplification, if memory serves.

Interestingly, Mark Levinson resurrected them after a fashion -- and, I believe, rather briefly (?) -- under the aegis of his post ML company, Cello.

http://www.celloseattle.com/ctdocs/prodserve/speakers/proamati.html

As an aside, and @dromunds probably knows this, there were two bargain versions of the AR-LST: to wit, the AR-LST2 and the AR-MST. The latter, with all cone drivers, is of interest to me because -- well -- as it happens, I have a torn-down pair of them sittin' in the basement. Another project for someday

mhardy6647

OK, I am being all OCD now.

for posterity:

AR-LST




AR-LST2




AR-MST




Now, in fairness, these loudspeakers are more "anti Bose 901" than are they "Bose 901 related" They are more about "dispersing direct sound", methinks, than "direct/reflected sound. But, still, they look kinda 901-sy.

Yes, I’ve heard the AR-LST2’s and in the immortal words of Lloyd Bentsen, “Sir, you are no LST”. Never heard the MST. Interesting info about Levinson’s speakers didn’t know about them. Below is the invoice from 1983 when I traded in my LST’s. I suppose it’s time to move on now. Lol. They were truly remarkable in the proper set-up.

mhardy6647

I am sure I've mentioned this before but my ugly-but-fully-functional pair of dump-find AR-3s gave up their drivers to a Cello Amati restoration project I am quite proud of that, as you can tell.

I've never seen nor heard the LST2, but I don't doubt your assessment. I am curious about the MST, mostly because those AR cone tweeters were really not bad. Safe to assume the MST's not in anything like the same league as the LST, tho'.

dromunds

My presumption would be the MST's would very significantly best the LST2's. I really like some of those vintage speakers. The original Large Advent is another of my faves. There was a real passion, they lived their designs.

mhardy6647

I liked Mr. Polk's Monitor Series Model 7 rather better than the OLA, which is probably why I (still) squander so much time here rather than, say, www.classicspeakerpages.net

That said, I heard a pair of OLAs that had been refreshed by simply replacing its XO capacitors. No more, no less. The new capacitors, if memory serves, weren't particularly boutique (I think they may have been the "Dayton brand - Bennic - polypropylene caps sold by PE) -- but they resulted in a phenomenal improvement in the smoothness & transparency of the OLA sound compared to what I remember.

There's a pair of Utility Advents in the basement that I really need to refoam & "recap" some day. Imagine that.

dromunds

I would say the Monitor 7's also fit into my "real passion, they lived their designs" category. I very much enjoy them also.

I plan to bequeath the pair of 7As here to the next generation of Hardys when I hit the dusty trail

Guess that's one way to break the rules...
