If you run them with a center channel on the long wall, they image just like live music.
Most stereo is a 'tunnel' effect. If you're not in the right spot, or if you turn your head, the illusion goes away.
At a live performance if the trumpet player is on the left, and you turn your head towards him, he gets louder.
With a L-C-R set-up it images the same way.
At a live performance if you sit on the left, certain instruments are louder, if you sit on the right, other instruments are louder. No matter where you sit, you hear a smooth 'curtain' of sound across the stage.
An L-C-R set-up behaves in the same way.

What configuration would you use for building a center channel
.
Klipsch recommended the Cornwall for a center between Khorns. A LaScala would work, too. Just try keeping the same mid and tweeter for the center channel. Bass is more flexable.
Actually, Klipsch recommends an all-horn system with the corner horn flanks, which means a LaScala. PWK's own setup at home had production Oiled Walnut Khorns in false corners and a Belle Klipsch in the center with resistor bridge feedning a 3rd amplifier (mono or 1/2 stereo) It's best d do the resistor box with all 25K ohm resistors and a potentiometer on the center to attenuate the middle -3 to -6 db from the flanks as required.
hi - do you think false corners "in the corners" might isolate some bad sheetrock/plywood wall resonances? these are excited even with harpsichord and acoustic guitar if I had less clutter then my 3rd K-horn could be rigged as center channel.
I was wondering if you took 1" thick MDF and made a false corner to put in your corner, that it would as you say, "lessen false vibrations" and make everything more supportive in the bass?
It does.
is tht a3/4" and is it attached to the wall? would simply screwing mdf or stiff plywood to flimsy walls help or just lower resonance of the wall? - my walls aer awful - 3/4" flooring grade plywood topped with sheetrock on 2x6 studs - vinyl siding as "outer wall" - they really resonant obnoxiously and render k-horn useless.
3/4" not attached to the wall. Here's a link:http://forums.klipsch.com/forums/p/71238/697931.aspx#697931

See below:
pretty cool - so the add-on tail is carrying most of the new wall's stress and the four eyebolts up front are grabbing 4 winged bolts up where "pressure" is minimal. You must be running a steep slope xover - is that BC's woofer? - how'syour whole K-horn play versus $$$$ upscale yuppie systems and what is/are your amp(s)? -- if I cna mitgate the drywall resonance then things will be better - whole dang house flexes & rattles with George Wright's organ cd's
it might help with MDF screwed to the walls (may just lower resonance?)- or might help more if spaced out on a frame - PWK used 2x4 frame and plywood. -have no mobility nor help so its been 11 years since seen MDF- around 1990 I've ran a few different woofers in K-horn and 250Hz tractrix Edgarhorn/LE5A with tweeter set back to midhorn driver plane. K400 sounds ok to me overall on several amps -my house wall resonances with basshorn are maddening so it gets shut off.
