Know anything about Pentagram Loudspeakers?

Sorry, not intending to poke fun, but that's not a great brand name from a marketing standpoint. Unless he was targeting fans of the darker 80's butt rock (not that there's anything wrong with that...).

Actually, about 95% of my listening is to classical music, generally on high quality audiophile-oriented labels, about 3/4 of it vinyl and 1/4 cd.

I've owned several large speakers during that time, including much more expensive B&W's, and sold them all and stayed with the Pentagrams.

Al,

Thanks VERY much for the info! I just measured, my woofers are indeed 10" with a 4" midrange. I was able to get one speaker playing today, and I was very impressed by the highs and mids, although the woofers may be a lost cause - the previous owner tried "refoaming" them with, if you can believe it, a strip of foam (like, couch cushion foam) and white caulk, lots of it. But the cabinets seem to have a lot of integrity and I think they could be easily re-veneered. The crossovers are probably the most substantial I've ever seen.

Your post raises a few questions which I hope you don't mind answering: Do your speakers contain any damping material, and if so, what kind and about how much? And, any ideas where on earth could I get a passive radiator that would be a suitable stand-in for the original?

I wonder if this Michael Levy fellow is still around? It'd be interesting to get in touch with him...

Thanks again, and best regards!

Hi Roy,

The Pentagram's were unusual in that they contained no internal damping material whatsoever. That was made possible by the five-sided truncated pyramid design, which has no parallel surfaces (you'll note that each side is opposite a corner edge).

I'm sure Bill LeGall can effectively repair the damage the other person did to the woofers, for reasonable cost. He is the best in the business at re-coning and repairing surrounds. His phone number and email address can be found at http://www.millersound.net. The main downside would be the time and effort required on your part to remove, pack, and ship the drivers, and reinstall them subsequently.

Before sending him my drivers for repair of the tears I mentioned, I spoke to him at length on the phone (he is a delight to talk to, and very informative), and he actually recalled having listened to the P10's, and commented that they were "very, very musical."

If your passive radiators simply need cone replacement, I'm sure he could do that as well. If they are completely missing for some reason, I have no suggestions to offer other than asking Bill for his advice.

Not sure what became of Michael Levy after his Pentagram days. I haven't seen his name come up ever since in any of the numerous audiophile publications I subscribe to.

Best of luck with them!

Some good additional background and information on the Pentagrams is provided in post no. 49 of this thread.

Among many other things, he notes that the P10's were the reference speakers of a reviewer at "Audio" magazine.
