Klipsch Theater Type TH-SR-3

[Dave A]

Looks to be a variant of a Heresy but way more complicated crossover. What was the purpose of doing this and did it require different woofers and mids/tweets than the Heresy's? If this crossover does something special I would like to build a pair. The guy had just the two cabinets and one TH-SR-2 and one TH-SR-3 crossover and all the guts were gone so I am left guessing. It wont take much to upgrade the TH-SR-2 which was designed to work without a tweeter.  Why would Klipsch elect to do that anyway? Kind of wondering if all the extra stuff on the crossover was for a K42 and not a K22 woofer.

Ooh, Interesting!  It's hard to tell, but it looks like a 2nd order low pass, maybe with contouring on the woofer (like E2), a first order high and 2nd order low pass on the squawker, again, maybe with some contouring and a 3rd order high pass fed by a resistor, to further attenuate the tweeter.  The tweeter circuit looks similar to a Type AA.

The network was designed for the speaker to perform in a large theater environment not for a K-42 woofer.

OK what would make it tuned for a large theater environment and what impact does that have on regular two channel stereo use?
