I know you've put the motor run caps into your crossover and are really trying to be patient and are letting them break in for a few weeks before you pass judgement on them but please give us(me) a hint at what you think of them in your system! These suckers are interesting: I have a situation where 10 uF 370V GE's sound entirely different(better) than the exact same cap but rated 440uF (taller can). WTFDIK!

Sorry to derail your thread, but do you still have those really great looking four π's?

...and Wayne, thanks for the compliment! As an impulsive tweaker, I must say that little I have done has improved on the already great sound of your design. Oil caps in the crossover and felt on the dust caps of the Delta 15s have gained a bit of clarity and smoothness but still the original sound is still there in all it's awesomeness!

I only wish I had the corners for the corner horns!

Too many things going on I never went back to pick up the the 30uF's I had Grainger bring in for me. Which is a good thing 'cause I went back up to 1600 Hz from 1200 and now need 20uF's.
Have to make time next week and will report, fer sure.

Does anybody think that false corners a-la the Klipschhorn recommendation are workable?

I think it's a good idea in principle, it's just that they're so cumbersome. But you could surely stack a wall of concrete bricks to form a false wall that was more solid even than the permanent walls of most homes.

They'd be about as visually attractive as the rest of my audio-related endeavors

But I do wonder – I’ve read how bass is “lost” through flimsy construction. Klipsch said to build a 2X4 stub wall sheathed on each side. But is that really the effective? Are cinder blocks really required?

Certainly, if the walls are free to vibrate, then you'll lose some of your energy in making them move. Or worse, if they're not damped, they can make their own sound, making peaks from panel resonance.

Most times, the drywall in homes isn't very solid but it's damped pretty well from the insulation behind it. So that helps. In some instances, you'll find a wall or panel without insulation behind it. They're troublesome, because it sounds as hollow as it is.
