Acoustic Research AR18 .. anyone know of them ?

I think that these were an 8" two way of sealed design if i remember correctly. Nothing to write home about, but a very reasonable little speaker. Obviously, a design of this nature and age would lack deep bass extension. Had the typical AR sound of the day i.e. very tight and quick bass, slight elevation in the warmth region, slightly recessed lower mids, small peak in the upper mids / lower treble, gradual roll-off on the extreme top.

A good combo that should be able to be found quite reasonably might be an older NAD or Proton integrated or receiver with the "bass EQ" feature. This added a bass boost at a much lower frequency than a typical tone control and would help to fill in the last octave or two on these. I think it was centered somewhere between 40 - 60 Hz or so. Since NAD's tend to be somewhat "warm and slow" themselves, try some Kimber 4PR to add some speed and apparent high frequency detail for speaker cables. A used pair of PBJ's from the CD player of your choice might also be in order, depending on the tonal characteristics that it displays. Sean

Thanks for the help. I'll check out their condition. I've purchased a Mission Cyrus 2 amplifier to drive them. This is a very detailed amplifier with great bass drive so it sounds like a good match. As for repairs, if any are needed it sounds like it would be worthwhile so long as the cost doesn't exceed $100 or so.

Try this website if you need info about them. Sean

This is an ancient thread, but I'm adding this in case someone goes looking for info on AR18's today. The next generation after the lenegadry AR7's from the 1970's, I have a pair of these which I've used since 1980. IMO they kick butt in a small to medium sized room, and suit my acoustic tastes perfectly. Not huge in the bass dept but lovely mid to righ range which is bright and clear without being abrasive or overcooked. A friend who visited me some 15 years after I bought them said "I forgot what those things could do." They can handle and punch out a lot of volume using a decent amp, and after 26 years I am getting my rubber surrounds fixed rather than buying a new pair of whatever this year's model is. I have heard floor standing speakers which people paid literally 10 times as much for which sounded inferior to these, with no decent midrange or top end (admittedly in a slightly larger room).

My advice is if you come across a cheap pair of these in working condition, don't even think twice about buying them. If they're dirt cheap, what do you have to lose if I'm wrong?

Thanks Fluke. I refoamed them myself for $25 in the end, and they work fine. I think if you find a pair for under $50 they may be worthwhile, but I wouldn't pay too much more for them.
