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.

I would sure love to hear those Machs you have redone!!
As I'm sure we all know Realistic's days of quailty are long gone but there is one more speaker that I would rate very high from them that was around with the Machs they cost only $20.00 more apeice at the time, and that is the T-200's , they were a Tower 3-way that could produce a Flat Uncolored Frequency Responce they had Gradual-slope crossovers that insured smooth transistions in bass mid and highs, staggered tweeters for time alignment so there were no sudden phase shifts or discontinities in the measured phase responce . and I tell ya the sound is just unbelievable cleaner than 2 bottles of 409

These had duel 10" active woofers that moved only half the distance of a single one +

I was lucky enough to pick up a near mint set off ebay for $158.00, although I replaced the surrounds on the woofers, there was not a scratch on these babys. they are probably one of the prettiest set of speakers I have ever seen they have the edgeless tweeter and a 6.5 mid they are cat# 40-2029 and the Shack has no record of these anywhere. The Machs were their Corvette and these were their Rolls Royce.

These T-200's can Handle so much power that it is said you can melt the L-pads before they will clip
My 4024 Machs I also bought on Ebay some time back Mint in the Box from 1979 and stored unplayed the entire time but for a price ---- $650.00 and was worth every penny there were no miles on them, and I think the age on the cones make them sound that much better , kinda like wine
