I have a pair of AR-10 Pi speakers which I don't use any longer and want to sell. My father bought them together with a Kenwood stereo sometimes back in 1979. Are the speakers worth anything?

The problem is, which I think is quite common after browsing the Internet for information, that the outer foam of the membrane on the subwoofers are drying out and starts to fall apart. I don't have the time and/or knowledge to fix them so...

Besides the subwoofer problem, I reckon that the speakers are quite nice since they are built in dark oak (I guess) and with 3-way switches for adjusting the subwoofer/midrange/highrange.

Anyone out there who could give me a hint on a possible value for the pair of speakers? I guess that there are collectors out there but I will probably not find one in my city (:

There have been a few products that took on the "π" or "Pi" name, but most are good to stop using the trademark when they realize it is already registered. This was one that slipped through, but it has been out of production for a long time. I don't know much about the specific model other than its name. Sorry I can't be more help to you.

The speakers have a "AR-10π" brand emblem on the front. The were sold in Sweden by the way.

However, the speakers I have looks exactly like the ones in this brochure that I found on the Internet:

FWIW, the old pair of AR2x's I had ended up being parted out, I then cut the front baffles away, and use them as storage/worktable in my shed. perfect height for rebuilding a carb, etc:)

the old sprague "compulytic" crossover caps spec was 20uF and they now measure 22.6uF, not bad for 31 year old electrolytic caps, the air core coils(1.27mH) were decent enough to recycle to the parts box also...ar level controls SUCK, btw. and what the hell was up with using a pot that varies the Z seen by the xover cap as the level is changed?!? that way the xover point can VARY with the level setting, then there can be a GAP between where the woofer dies like hitting a brick wall at 1kHz. and wherever the tweeter decides to come on line:(

"sealed woofer fart boxes", what was the question again? Sam

Any of you ever read or seen anything about Kloss? He was a long haired, pony-tail wearing fellow that was responsible for the AR speaker line and many other audio goodies. A really impressive guy.

Are you thinking of Henry Kloss? I think he "invented" the first Acoustic Research speaker in the early 50s with another guy- then went on the found Advent, was in KLH, Cambridge Soundworks, recently did the Tivoli radios. I think he passed away last year. Very productive life dedicated to good sound- even if he did give up so much bandwidth for size!
