I was given a pair of Mach One's today. One is minus the woofer the other has some cone damage and needs foaming. When I was a kid I drooled over the pair a family member had. The midrange and and tweeter are both horns. (If I recall right, these were rather pricey for the day about $750 for a pair in 1980) I want a quality 15" that isn't going to cost me a fortune. Any suggestions.

We would need to know rough cabinet dimensions and where it would be crossed over to be of any help.

Hopefully someone here has actually dealt with these speakers before and can give some advice, but if you can get volume and crossover, more people can chime in with advice.
I have no idea what the cross over frequency is though the original was a 4 ohm 15", my cabinet volume in the main compartment is about 1.9cf the upper portion of the cabinet is sealed with a 7 ohm midrange horn.

I am tempted to leave the woofer off and use both sets of horns as a center channel project. Any thoughts on that?

I put a pair or pyle 15" subs in the cabinet just to give it a listen this morning. It wasn't the best low end I could have put in them, but at free they work better than nothing and since it was the highs and mids that really make this speaker it will be a great addition to my garage/workshop sound system. Besides when the lathe is running it ends up drowning out the details.
