Seadog

H2G, Thanks a bunch for finding and posting the link to the manual! I must be a lousy internet searcher because when I searched I only came up with spec sheets and sales brochures. David

Mine are '89 with AK-3 and I like them very much. Also, don't be concerned about the plastic horns, they sound fine. No ringing like the metal horns (no caulk required).

I ordered a "used" Philips 963SA from a NYC electronics store and it arrived today. It came in the original box that said "demo". It was the last one they had, so I guess it was their store demo unit. Not a scratch on it, and it came with the remote, however, no manual. I paid $117 including shipping. I would like to obtain a photocopy of the manual. If someone with a manual would be kind enough to copy it for me, I would gladly pay the postage plus $10 for your troubles. Thanks, David.

What is the frequ range of the K55 ram87 ---------------- Here is my understanding of where and how the P-trap works: The simple crossover networks like the B used in the Cornwall used only a high pass filter (a capacitor) for the squawker rather than a band pass filter (which would include an inductor and a cap). The idea was that the squawker naturally cuts off at around 6kHz, so the high pass was all that was needed. However, the early K-55-V drivers (before about 1980) had the 9kHz peak, and need the P-trap to eliminate the current at 9kHz. The newer K-55-V drivers (with the solder-on connectors) dont need a P-trap, even with a simple network, because a design change in the phase plug fixed this problem. Also, networks like the ALK dont need a P-trap even when using the older K-55-V. The P-trap works because at 9kHz the inductive reactance equals the capacitive reactance. The current through the inductor and the capacitor are equal but out of phase, so the impedance of the circuit is extremely high at that frequency. (Disclaimer: I am a mechanical engineer and it has been 25 years since I took a circuits course).

This driver is supposed to fall off naturally at around 6kHz, however, for some reason it flares up again at 9kHz and can create a harshness. It is simply a 0.10 mH inductor in parallel with a 3.0uF capacitor on the squawker's positive lead. Search the forum for "P-trap", there are several good threads on the subject. To my ears, the P-trap also seems to clean up the sound from the tweeter, adding more high end detail (because the squawker is now dead above 6kHz). Aside from the caulk and the P-trap, I've done nothing except experiment with various capacitor types in the type B crossovers. The best "tweek" (for two-channel listening) was setting up a derived center channel Cornwall and going with tube amplification (Scott/NOSvalves).

"In my experience, it is lots easier to remove and reinstall the horns in a Lascala if you first lay the Lascala down on its front." That goes for the Cornwall also, especially when working alone and trying to align the holes to re-install the horn.

BTW, the Cornwall horn takes about 65 feet of the rope caulk to complete (one layer).

Here is a caulked horn in a Vertical CW. You may also notice the P-trap I built and installed. I installed the P-traps about a month before the caulk (did not want to change two things at one time). I think that the P-trap made a more dramatic improvement than the caulk, although both are must-do tweeks for Cornwalls (IMO of course).

That horn was caulked by forum member Good2Bhome who came by a few weeks ago to show me how to properly caulk a horn. This is Mike in progress.

Here is a caulked K600 for a Cornwall.

Tom, do you suppose they have a pair if Jubilee's in Indy? If so, we MUST hear them too, behind the curtain of course .

I'd like to hear a comparison between the Premier, the RF7, and the K-horn. A/B/C a pair of each in the same room.

Welcome to the forum and congrats on your new Klipsch speakers. I was at a Best Buy recently and heard the F3. It was clearly the best speaker in the house. The sales rep said he loved to demonstrate the Klipsch HT. "Drumline" is a great movie to showcase good speakers. Klipsch used a clip from that movie to demo one of their HT systems at last year's Pilgrimage. I bought a copy when I got home from Indy just to hear that part on my HT.

Daddy Dee and Tony, you guys are very fortunate to have had this experience. With only one show room (Miss Valerie's home), there is a very short list of those who will ever get to hear a Jubilee, much less buy one (or two). Maybe Klipsch will neglect to pay the maintenance fees on the patent and someone else can market this speaker.

Thank you Amy and Trey! (and the CEO and CFO and COO, etc. etc)

Hopefully I'll get one of these. I ordered one about eight weeks ago from Target.com. It came about three weeks ago and lasted about 10 minutes before the left channel started distorting . I returned it and they are supposed to replace it ASAP, but they said it might be April. I have not heard of anyone else having problems like this, so maybe this was the exception. Anyway, before it started acting up it did sound good on the K-horns. The bass was weak, but the imaging was very good and the sound was detailed and clean.

Congrats Gil. Another forum member scores big!

Thanks for posting. Good description of the 3-speaker arrangement.

Very disturbing. A must for every kitchen.

Come on Trey. Please firm up the date. The flight prices are going up! Last week I could have booked a flight for $223. Today I checked and the cheapest flight is now $288.

I picked up this DVD based on the recommendations on this thread. I've never even owned a DT CD, but this DVD makes me appreciate this band. These guys are very good musicians. Extremely tight band, especially considering the speeds at which they play. An excellent widescreen video, 5.1 audio, live performance DVD.

I'm in Minneapolis this week on business. So tonight I checked out a downtown jazz club, the Dakota Jazz Club and Restaurant. I highly recommend this place to anyone who enjoys good food and good music. The food is excellent, and they have live entertainment every night. They book local and national talent. This is a very classy venue.

"I'll know later what time I'll be home Sat night. Exotic entertainment anyone???" What's this? Are you bringing the bridesmaids back to your place?

Do those plates rattle when you crank up the Cornwalls? (I'm serious, my wife had some plates on a shelf that rattled badly when I turned up the K-horns). Nice looking room. So what part of the Pilgrimage are you hosting there?

I can understand why her husband never returned from the war!
