The LT-12's are 12" with whizzer cones and the cheaper T-35 type horn with internal crossover.

I measured the LT-12's installed in the Karlson cabinet and they play nicely down to approx 60hz(fs of LT-12) which is okay if you use a sub.

Efficiency is approx 94db/watt by my guesstimation.

Local pickup in Columbus, Ohio as they would be difficult to ship.

Asking price $450.00 or possible trade for tube amps/JBL or Altec drivers/wood horns.
