Finally cabled it up. Sounds Amazing! Well rounded crossover and very smooth transitions with detail; great at any level and music type. No component is over powering the other; just solid well balanced sound. And I think your ears will bleed before you hear any distortion. Very neutral sound w/o colorization.Bass has that punch and the top end opened up whereas the tweeter and mid just melded together. They Rock! > Is it a Cornscala now?

Final components; a mix of Klipsch upgraded with new.

1983 Cornwall 1 1/2's. Birch raw cabs. (mint) - I was hesitant to cut into these - oh well.

K-51V Mid's with new OEM diag's from Bob.(rare)

1526C cast woofer from Bob ( very nice, more clarity/punch then orig's )

Original K77M's (ceramic sq, sound very nice, ohm out great ). I believe the treble opened up dispertion due to flare opening on mother board.

Dave's Fastrac Cornwall Horn ( a valuable addition ) a cornwall weakness. Definite plus

New 16g wire 112 stranded from Knuconcept ( good stuff, quality copper ). Orig wire and spade clips are cheesy. Def +

Sonic + Jupiter VT Flat Stacks caps from Jeff ( very nice, no more harsh plasticity or listening fatigue, great harmony, detail, noticable improvement ). Def +

other

Cedar xover boards with full felts pads for vibration. No performance enhancement here. Maybe it'll keep the bugs out . lol

Custom wood capacitor mounts. Just because, those caps are big.

Cut out a 5 inch sq of the orig paper dampening material where the mid horn meets/presses close to the back panel and in it's place put a piece of 3/4 in soft foam for horn dampening. Put 3/8w in x 1/8h in weather foam strip around the back panel board to help seal it..

So thats about it. Did alot of research and comparisons, I want to say thanks to Bob, Dave & Jeff who have helped me; really appreciate.

Project completed. Hope this info helps~

Thanks~

Thanks. I forgot though ... . to make new grilles. Not sure what to use, 1/4 in sheet ply?

If you have a 'Lowes' l would use the 3/16 Masonite. It is dark in color and smooth on both sides, no need to paint before covering.

Speakers look great nice job.

Not exactly sure where I want to go with that yet. However, it probably won't be tubes or complete solid state. I'm looking for something in the middle like a vintage amp with discreet components. Mac 2505 or 2105 for example. Currently it's connected to a rebuilt 1978 Yamaha CR-1020(only 1 small IC).

I did notice that after testing the Cornscala seems a bit more forgiving to what's pushin it then before. The sound basis is there.
