Can't speak to audible superiority, but I used WIMAs to re-cap my Corns. The four lead box looks good for a PCB based crossover.

As the OP has probably figured out by now, Vas is meaningless for compression drivers. Compression drivers, and well-engineered domes, have back chambers and internal damping tailored to their characteristics. Attempting to extend the lower range of these drivers by enlarging the back chamber means you lose the damping and the voice coil/diaphragm assembly will injure itself trying to go lower.

The basic chemistry of electrolytics has not changed in about 75 years, so there are various tolerances of 'lytics but at the end of the day, a lytic is a lytic is a lytic. . Solen polypropylenes are not expensive and sound just fine.

My center's mid/tweet baffle is titled 10 degrees to aim at the ears of seated listeners, not their ankles as would be the case if the baffle was perpendicular to the floor

Yes you can build a center from Klipsch parts, I did. Two K-1077 8 inch woofers, the K-401 horn, PV5 driver and Crites CT125 tweeter. Bob Crites told me that best results would be to use a K-401 horn instead of the K-601 horns in my flanking Cornwalls. He was right since the center channel is predominantly vocals. A grille that matches the Corns covers this in normal use. The CRT based TV is long gone replaced by a flat panel.

Glad you have a cat to appreciate the Klipschorns. Cats and Klipsch products have a well documented synergy. I roger what Chris said above. The Khorns need room to sing.

well,so much for that theory! 😉

Thanks Chris. REW it is.

I am finally ready to buy a measurement system. I need a calibrated mike, a signal generator and software to display frequency, impulse and distortion. I've looked at various reviews of the packages out there, and I need something better than 1/3 octave resolution. It would be nice if it is Mac compatible, but I have a Win laptop so that's not a deal breaker. Any recommendations welcome and TIA!

"Delivered after that date" I think is the key phrase. The four digit units were probably existing unsold stock in the distribution pipeline.

I despise Word but I have to use it at work. I use WordPerfect for all my literary and personal writing, as do many writers and journalists. I am sad that there has not been a Mac version in a very long time, but I can run WP in my Parallels Windows on my iMac. I gave up on PS and their silly subscription model long ago and use a UK program called Affinity, which is full-fledged suite of image apps. A lot cheaper and more user--friendly as well.

Thank y'all. "The Faubourg Marigny of New Orleans: A History"

My book signing at Faubourg Marigny Art and Books (FAB) 600 Chartres (corner Frenchmen) on 9 November. The mime helped out for a while, then went to work the freer-spending drunks on Bourbon. Said he could make $40 an hour on good night. Some of the tourists on Frenchmen did not tip him after taking selfies with him, which is bad form. I gave him some bucks for his time. AFAIK, this is the last bookstore in the parish downriver from St. Ann street. La Librarie on Chartres closed closed this year, sadly missed. FAB is a great store with a wide selection and the owners were super to me. Since the book is a history of the Faubourg Marigny neighborhood, I wanted to have a signing there, but the store was closed for a few months, for remodeling under new owners,

The worst candy I ever tasted was a hybrid, Gummi Worms soaked in vodka. Jello shots I am OK with, but Gummi Worms have to be chewed, and it was like eating fishing lures. Reminded me of the time when some Italian friends gave my parents some candy from the old country. I was about 5 and of course I helped myself. A few minutes later I was heaven' up. My parents realized these were liquor-filled. Liquor-filled candy wasn't legal in the US until much later so no one suspected they might be filled with booze.

No 8's jersey reads a lot like PWK's favorite word...

102 dB average with peaks to 106 is the loudest I can tolerate in my primary listening room.

Go ask Eric When he was just small...

The Arizonas are mylars...at those prices...wow

A side note...Wendy Carlos uses Cornwalls as her monitors

Don Keele worked with Newman at Electrovoice and with PWK at K&A so I feel pretty confident that they met through Keele or at a convention

BeFuddledinMn said: "Second, does the introduction of the new mumps tractrix midrange on the Cornwall IV in addition to the Forte III, implicitly confirm the obsolescence of the k-400 to k-700 series of exponential horns?" The K400/401 was sized to fit in the existing top hat of K-horn (sized to fit the original K-5 series). Everyone agrees that the K401 is too small. To change it to a larger horn would require making the top hat significantly bigger, which would change the proportions of the Klipschorn. It seems that Klipsch was not willing to do that. As far as "obsolescence" goes, Klipsch has been moving to tractrix for a while in other products. So, yeah the rest of the exponential horns are being slowly obsoleted, but the proportions of the Klipschorn seem to restrict that system to the K-401 for the foreseeable future. I don't know what kind of crossover design Roy used to tame the K55/401, but from Stereophile's review, which of course was botched, it looks less jagged than the response Heyser measured in 1982. Of course, it is risky to compare measurements between two different set-ups seperated by 37 years of time.
