Jensen will have the number PL15 ink stamped on the outer edge of the basket as viewed from the rear. Usually has a silver colored basket and cover over the magnet.

any idea what's under the hood? K? mid driver, chrome tweeters? Jensen, EV, or Eminence woofie?

I wouldn't. You could also staple convoluted foam in there. Klipsch uses little felt feet (puppy feet) to keep the staple from tearing out when they use this material in their pro speakers. Generally you're just trying to damped standing waves inside the cabinet. Dampening ONE of each of two parallel sides is sufficient- ie back, one side, top.

If you were closer these would be mine by now.

The woofer and network were the main portions of the upgrade kit imho.

Gentlemen, Buy or Don't Buy please. This is a For Sale column.

numbers were usually used for grille codes black = 17, cane = 3. S usually meant 'factory stained' in the case of LS cabinets. Were these stained and someone sanded them down?

a lot of the pro stuff uses fine thread bolts and fittings. Try 10-32 Bruce.

Thank you Mike and Roy!
