You are correct in that the "center" effect was a bit underwhelming as it only played the "stereo effect" in the center.
It was the thing-of-the-day...

Here is another take on it.

I ended up taking L/R from the RCA outs and, using two 27k resistors, and developed a mono signal for the true "Center"..  Of course I had to buy another DC-150 to power that.

Mea Culpa: Maybe this (develop mono signal) is was what was suggested in "Dope from Hope" - I have to find that binder - it was quite some time ago.

1st the hair, then the... what was that again?


Yes, this is the method Klipsch published. I built one with a volume control and used it to feed a mono amp running a Klipsch Cornwall center channel (I had a pair of Klipschorns for L/R). The volume control allowed me to adjust the center channel volume to achieve a seamless corner-to-corner sonic image with just about any recording (some produced better results than others). As long as the room had corners for the K-horns the results were extremely impressive.

I eventually moved into a home without natural corners in which the K-horns sounded pretty bad, so I went full-on Klipsch THX home theater and sold the K-horns (used the Cornwall as the theater subwoofer for a while).
