The receipt is in a box from the recent move, still unpacked. IIRC it was 79 or 80. RatShack was called Tandy down here and have changed hands at least once. Even if they did offer the warranty, I'm not sure they'd still honour it and for the $ involved, it's not worth the hassle. Mine are fine as they are.

Got to wondering if I could re wire the Mach Ones for woofer only?
Any thoughts on this?
You could, but the M1 xovered to the horn at about 800Hz so you'd need to change the xover to a lower F. Integrating it as part of the existing Klipsch xovers would be a true PITA and there would be phasing issues at LF between the PR bass and the M1.

Hello All,

I have designed speakers and tube amps for the last 25 years. I have taken measurments on the mach ones and have found they can be made much better. I am looking to see if anyone have the information on the original 4024 crossover parts. The pair I have and have done the testing on is the 4029. If anyone has the list of crossover parts for the 4024 or a hi-res picture that you can see the values it would be helpful. Please contact me if you can provide either of these. And Thanks!
