This car was on display in the Klipsch exhibit at CES.

Sent you a PM.

The re-capped crossover was installed on the left front speaker. The stereo was set to Mono. I listened for occasional sessions a couple days, then swapped the OEM crossover from the right front speaker with the re-capped one from the LF. The effect that I seem to be hearing after the left and right swap is that the re-capped crossover is filtering the signal better. The audible difference is subtle, but good enough that I will proceed to re-cap the other crossovers in my system.

If you have room for a matching center speaker, that would be ideal, but a smaller one from the KPT series would also be good. The surround and rear channel speakers that you already own should be fine for a home theater..

The serial numbers on my KPT speakers indicate the model year 2008, so I decided to replace the old yellow capacitors with some new black caps.

Looking good!

You might need go to Settings on your TV, select Audio, then Digital Optical, then PCM. Different TV brands may use other names on their menus, but this should help you figure it out.

Recessing the woofer sometimes requires a thicker motor board, especially with a subwoofer. On the mid horn above, I glued on extra backer board where the mounting screws attach. The horn quoted above is a ZXPC 18x10 and the driver is a K-69A, but I have used a few different drivers, all with good results. If you are modifying a K-horn or La Scala and keeping the passive crossover, the factory stock K-55 with an adapter is a great driver.

I have a picture frame of quarter inch thick wood bolted to the K-402 mouth flange. Its purpose is decorative, but maybe it also adds a little bit of stiffness. The effectiveness would probably be relative to the SPLs in the room.

First thing is to test or replace the fuse.

Yes the wires to the woofers on most K-horns are soldered on.

Yes, I did that to the horn on a center channel speaker last year. When I changed that motor board a few months ago, the same horn was surface mounted, because the horn shape looks good on the surface mount, and because it is less work than using the router to cut the recess.

I like my Klipsch speakers better than the very high priced Wilson Audio speakers, but that company does seem to have a good philosophy about loudspeakers, and continuing the work of the late Dave Wilson.

I swapped out the old original K-1133 midrange drivers a few weeks ago and put JBL Selenium D-405 2" drivers on the K-402 horns. These and the B+C DE-120 tweeters and the KPT-415 woofer combination, bi-amped with separate bass/treble passive crossovers sound excellent in my home theater room.

In my experience, compression driver mounting studs are common. The K-402 throat does create a tight tolerance, so it is helpful to remove (or install) all four nuts using an even pattern, not just completely removing (or installing) one fastener at a time. After doing it a couple times and learning the technique, it becomes fairly easy.
