majick47,
Thought the same thing...went there before I posted here. Did a search and came up "no documents"

Strange huh?

Searching the catalogs does require a bit of historic knowledge too: 1979

They are very nice speakers, I have 3 of them, refoamed myself. Don't remove the fiberglass bucket underneath the woofers, its important in helping to dampen the woofer in that cabinet. OTOH, you can improve the simple crossover by replacing the caps with new and bypass or charge couple them. Don't know that term? Do a search at Lansing Heritage to find out.

Bart
