It was gratifying to see that the Director of Bands, Grant Okamura, chose speakers that are twenty years old and out of production for the band practice room. Obviously, he chose them because of their ability to accurately reproduce the recordings of their practices. A single microphone hangs from the ceiling approximately 10 feet in front of each speaker. Unfortunately, I was unable to find out about the rest of the sytem, or to hear them in operation. Grant is a trumpeter, so we know he likes horns.

It's difficult to see from the photo, but they are IIs from 85 or later. They do not have the metal EV tweeters. The plastic horns are flush mounted on the motorboard. They are recessed into the acoustical tile, i.e, they appear to be thinner.

Greetings from Honolulu. Look at what the University of Hawaii Music Department has hanging on the wall in its practice room. Its mate is out of the frame to the right.

That works. I'll plan on AKFest for Sunday. Thanks

Craig, Where and when is AKFest? The site is down for maintenance.

Craig, I'll try to stop by the AKFest. Perhaps we can do Chicago another time.

Wait!! Sunday April 10 you say. I'll have returned from getting leighed by then. Craig, would you be interested in sharing a ride? I could drive. Do you go and return the same day? Send me a PM if you want to discuss a ride share.

Craig. We should share a ride to one of these some time. I could be standing at the side of I-69 as you head toward Chicago; we could then collect Audio Flynn as we left Metro-Detroit. I'd go to this one, but I'll be in Honolulu chaperoning a high school band trip. It's dirty work, but someone's got to do it.

Fantasia?

Tweeter diaphragm replacement is easy. I did it many times without a problem.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> I know this is heretical, but in the mid 70s I used four Speakerlab SK-Horns powered by a Dynaco ST-400 for a mobile DJ business. Tweeters were regular victims of 600 watts (300/side into 4 ohm load). I had an open account with EV. Id call them on a Friday and have new diaphragms by the following Tuesday. As Chris Robinson recommended, I always kept spares on hand. Since switching to more realistic power and decibel levels, Ive never blown a tweeter in my Hereseys or Cornwalls.

Permanently attached false corners worked for me. I know this is heretical, but in the mid 70s I used four Speakerlab SK-Horns powered by a Dynaco ST-400 for a mobile DJ business. Knowing the speakers would be moved often and that real corners would not always be availableread NEVERI used the plywood shipping crates to make false corners attached to each speaker. I never measured the difference in bass response between placements in real corners and freestanding with the false corners, but there appeared to be no difference. In either configuration the bass was prodigious and tight. One customer who called to schedule a return engagement asked if the price quoted included the drummer. It was all I could do to convince her that there had not been a drummer at the earlier engagement.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> The one time I met PWK he was surprisingly diplomatic about my confessed use of the Speakerlab copies. He allowed that it was better to subject the impostors, rather than real Khorns, to the abuse of 600 watts of SS power, junior high students and frequent assaults by hand-truck. Actually, they were perfect for the task. Unloading four black plywood obelisks never failed to impressneither did the sound. Invariably, as the first speaker was unloaded, someone would ask, Is that the speaker? to which I would reply, Yes. There are three more. The size made it impossible for someone to walk off with one of the speakers when my back was turned. I did have to put hardware cloth (wire mesh) over the mouths of the squawker horns and over the backs, to prevent mischief. Once a napkin had been stuffed into a squawker horn and another time a kid unscrewed an Atlas squawker driver. I got it back after the principal of the school announced that there would be no more dances until it was returned. If I ever supplement my <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Cornwalls and Hereseys with Khorns, I will again go the affixed false corner route.

Check out the description (revised) of some Hereseys on eBay. One can only wonder in what way it was revised. "UP FOR AUTION IS A PAIR OF HERESY KLIPSCH,TYPE H-OL.THEY HAVE CONSECUTIVE SERIAL NUMBERS 148X735 AND 148X736.INSPECTED BY JUDY PURTLE AND TESTED BY RICKY CLARK.THEY WERE MADE IN 1982.PLEASE NOTE THAT ALL COMPONETS ARE ORIGINAL.THESE SPEAKERS ARE IN VERY GOOD CONDITION.THEY DO HAVE SOME MOUNTING HOLES IN THEM BECAUSE THE WERE HUNG IN MY LIVING ROOM FROM DAY ONE.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> "THE ONLY REASON WHY I'M SELLING THESE BABIES IS BECAUSE THE WIFE WENT OUT AND PURCHASE A BOSE LIFESTYLE SYSTEM.SHE CLAIMS SHE WANTED SOMETHING NEWER LOOKING.TRUST ME SOMETIMES I LOOK AT HER A FEEL THE SAME WAY ABOUT HER.THE HERESY SOUNDS SO MUCH BETTER,BUT YOU CAN'T ARGUE WITH THE WIFE.IF IT COMES BETWEEN MY LA SCALAS AND MY WIFE THATS EASY(SHE'S GONE) "IF YOU LOOKING AT THIS YOU KNOW THE SPECS ON THESE."

I'd like a parts list and schematic please.

Dr. Bill, This will make it easier to get to the item. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5760518612 Are the center channel devices all gone? Did you take a picture of one? I heard PWK demo the 3 channel years ago. It was impressive. Maybe someday.

Does the Dearborn Almas store stock Heritage? The <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Almas in Birmingham doesn't. They have performed expert work on a Dynaco tube amp at a reasonable rate. They seem knowledgeable and aren't pushy, but, like most places these days, they emphasize HT over 2 channel. I assume from your avatar that you're a Spartan fan. If you ever spent time in East Lansing did you visit the Stereo Shoppe? They were (are?) a Klipsch dealer. In the late 70's I attended an event put on by The Stereo Shoppe that featured PWK and his three channel setup. He and the setup were most impressive. I hope the Spartans play better against Old Dominion than they did against Iowa.

A photo of the doctor's good work would be appreciated.

Now that Russ <?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> taught me the ropes, I cant resist pasting links into posts. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5754894362

This could not have worked out better. Gil, a worthy recipient, need only make a short trip to collect his fantastic bargains. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Id feel worse about not hitting BIN, but for the fact that two weeks ago I scored Cornwalls (30 minutes away) off eBay for $475.00. I thought those were a stealand they werebut it was a misdemeanor; Khorns for $700.00 is a felony.

Thanks for posting the interesting EV literature. So these "Cardinal IVs" are similar to Georgians, but they are not mentioned in the posted EV literature. Would it be correct to assume that the cabinet doors on the front of the Georgian bass bin are a purely cosmetic attempt to disguise the large enclosures? The violin-like openings would defeat the operation of the bass horn. The Cardinal IV appears to be more like a Khorn than the Georgian. The violin-like openings (they must have a real name that's unkown to me) on the Cardinal IVs must be purely decorative, for the same reason. The picture that shows the woofer makes it appear that the interior surfaces of the bass bin are finished. It's not clear from the description or the photos whether they are 3-way or 4-way. Has anyone seen, or better heard, EV Georgians or Cardinal IVs? They probably sound pretty good, but anyone who would pony up this kind of dough is buying antique furniture as much as speakers.

Congrats. I can't believe they lasted that long. Please let us know their condition. I'll bet they're great. You couldn't go wrong.

Thanks . I think I've got it. If the link to this site (http://silverstone.fortunecity.com/cosworth/633/Rotus7.htm) works, you'll be able to see the car (red one) I built.

Thanks for the reply. I'd like to say that your reply has resolved the mystrey, but it's still clear as mud.

How does one insert links and photos directly into a post? I know this has been explained before, but my search to locate the info was fruitless.
