Yesterday I was out junkin and picked up a pair of Isophon speakers. These are a three way (I think, you'll see what I mean) and use the Isophon P30/31/10 12" drivers in a 2.5+/- cf BR enclosure. Above that are a pair of Tonegen TW26 cone tweeters and then there is a Pioneer PT-3 horn tweeter. The Isophons and Pioneers work but the onegens are dead (I think).

Now I haven't bee able to get at the XO (yet) to tell whats going on. Obviously the Isophons are a hi-e driver. Does anybody have the T-S params on these by chance?

The cabinets are in decent shape still an can be brought back with a little elbow grease. After listening to these and playing with some tweeters and XO points, I'm half tempted to gut the Tonegens and Pioneer and drop a horn (about 800 Hz) above the Isophons.

Anybody have any experience with these drivers? That and can anybody recommend a decent (affordable) horn and compression driver that might blend well above the Iso's?

TIA,
Scott F.
