The woofers I have are definately the 8ohm models, it says so on the bottom of the drivers metal back plate. So you are telling me if my original 4024 blow something, they will not honor the lifetime warranty? It figures!

One set of Mach Ones I own are the lousy 4029. When the woofer's surround gave out, rather than replacing them, I had the speaker completely redone from the inside. New VERY expensive crossover system with time alignment built in, new 15" TAD coaxial driver with a 5" midbass driver behind the dust cap(which they call a dispersion screen), new mid and high frequency drivers also by TAD.

When my buddy who happens to work for Klipsch finished the remodeling job on the speakers, they sounded way better than the originals(4024), and better than any horn loaded hybrid I have ever heard. The sounded so good, that I had my friend match my center and surrounds with the same drivers(the are also both horn loaded hybrids), and crossover unit so I could use them for a 5.1 monitoring system in my old studio.

I would be interested in purchasing another set of the 4024 If I could get my hands on a pair.

I guess JBL has never heard of the HPS-4000XL system by John Allen. He was the first person to develope a horn loaded full range speakers with a horn loaded bass bin capable of 135db at 25hz. They are big suckers though.
