I currently have a pair of early Heresy speakers with good drivers. These speakers sound good, however, they really lack the bass response I am looking for. If it were just the bass, then I would just deal with it and be happy. However, the cabinets are falling apart and in need of replacement. So…

Would it be possible (desirable) to mate the Heresy tweeters, squawkers and crossovers with say a 4pi LF driver and cabinet?

The next step up the Klipsch product line used to be the Cornwall (15" woofer & bigger box) and I believe it used the same mid and tweeter horns as the Heresy.
Consider either a Thermonic 4 Pi or a Theater 4 Pi system. The old parts could be cobbled into a new system. But then you must deal with a three-way crossover and a few other problems. The costs of parts to build new 4 Pi's isn't a whole lot more than repairing the Heresy/Cornwall system. Personally, I would sell the Heresy stuff on e-bay and use the proceeds for a pair of Theater 4 Pi units. I've owned both speakers. 4 Pi now, and Heresy's a "few" years ago in my student days. Just having new drivers to work with would be a big plus.

seven π cornerhorn

Get the best woofer you can afford and implement it in a π cornerhorn. Since the Klipsch midrange and tweeter were baffle mounted, I expect the crossover is already worked out to sum properly and I also assume the midrange crossover frequency is pretty low. So just crossover the woofer in the π cornerhorn at that point and add a conjugate Zobel and it would work very well.

Those are some very nice cornerhorns!! Do the cornerhorns have to be put exactly into the corners? Or can they be toed out a little?

Also, what would be a good woofer? I have seen the JBL 2225's mentioned as good woofers. What kind of bass response could I expect?

btw, I am using 300b set amps.
