    Cornscala for sale

    Sorry but no trades for speakers as I am trying to whittle the piles down to just what I like and or actively listen to. I am in Giles County off of I-65 exit 27. You would probably come down HWY7 through Columbia and you are welcome to stop in and listen if you wish.
  2. Which plastic were you thinking of? I know the Delrin and UHMW plastic I have been buying for some time would be cost prohibitive.
  3. OK folks cleanup continues. These are free to anyone until next Friday when they hit the burn pile. Hate to do it but the surplus things have to leave here one way or the other. Take these home with you when you buy my cheap Cornscalas ;D

    KSM2 for sale

    Continuing my epic saga of things I want gone because I need the space is a set of KSM2's. They have been up for sale a while and I am getting close to selling the parts out of them and giving up on selling working speakers. $275.00 which is pretty much what the two K-43-K woofers would run you on EBay. Pick up only.

    Cornscala for sale

    Bump and I am surprised they are still here too.
  6. My intent is to perhaps do this on a set of 1" Baltic Birch Super MWM bins I will build later this year. I want to be able to haul these around and it seems the fiberglass is best at resisting problems. OK that MDO and HDO sounds interesting and I might try that for a 1" thick Chorus speaker build I am contemplating. I only see 4' widths though so for the Super MWM it might be a problem to use. That Chorus particle board crap drives me wild and I have a pair here right now with water problems from a potted plant would be my guess. Once that junk starts swelling even humidity becomes a problem. And of course the screw hole problems. As far as I am concerned there is nothing good about particle board in speaker land unless you are a penny pinching corporation cost cutter who does not care about customers. When I was in St Louis at Tim's to pick up speakers a while back he had a gutted MDF cabinet to be thrown into the dumpster. While his two helpers were picking it up and complaining about weight Tim was explaining how they were from a rare set of past JBL things and BOOM this bin hits the bottom of the dumpster. Silence for a second and then words of astonishment over the complete disintegration of the cabinet. This thing looked like a tank until it didn't and that's the whole story of MDF. Looks good and fails in every important metric except stiffness which had it's worth proven when stiff and brittle collapsed into a pile of rubble in the dumpster. Or turns into sawdust because of one potted plant.
  7. Sometimes a search fails because you don't know what to type in. Today I am trying to find out how Klipsch put the fiberglass coating of the Pro line speakers on and not having any luck. Anyone have a link to point me to? Now I would also be interested in an alternative to Duratex which I like but is not as resistant to damage as I would like. I have thought of epoxy coatings but once again like Duratex they are subject to chipping and scraping damage much more so than fibrglass.
  8. The phase plug on the 1132 looks exactly like this. This leads to a question namely since the diaphragms are interchangeable how do you tell what the driver was originally? Is the only differentiator the diaphragm?
  9. OK I dug into the four KP456 horns from a guy in Boulder Co and finding really ugly stuff. Two work and two did not. In the one the edge of the diaphragm is cracked and on the other the phase plug broke into two pieces and both became loose and the diaphragm was a pile of Ti flakes. Taking the diaphragm off of the others it appears the phase plug is glued as it is in there solidly and looks like glue is the only way. Is this correct? Also what exactly is the difference between the 8ohm and 16ohm diaphragms practically speaking in relation to the crossover? There was only one crossover made for these so I assume both will work fine just as long a they are matched in ohms to each other. This leads me to asking also if anyone has any of these drivers to sell and what would you want for them.
  10. If MAGRF7 is not interested I might be.

    KP600, KHJ/KPT402, KWO for sale.

    I am interested in the 402's
  12. Hi Carl, I thought about that but they are nothing special. I will do so later today.

    Wtb Klipschorns

    I have to wonder about dealer incentives more than anything. There are surely enough Klipsch fans to support such things here. But if B&W offers dealers say stocking no charge for demonstrators and lets them keep more of the gross sales in their pockets why in the world wouldn't they prefer that which makes them more money. After listening to HiFi Buys sad top end sound systems there is no doubt in my mind if side by side one could compare B&W to KHorns and up Klipsch could sell their better sound quite easily. The B&W 12,500 and 22,000 $ systems were less than a pair of LSI's sitting on top of a pair of KP480's I had when I visited them last year. I mean WAY less. But the B&W had that $1,000 diamond tweeter diaphragm so as long as they could sell that card stating that along with the system it would be good to impress your less than knowledgeable friends with. When I went to see Cory's Jubilee system with it's price tag this system would have ended B&W sales to anyone who valued audio over ego. Audio is a strange world to me where let's disregard the result of what we bought if we can first brag about what we spent on it being such a common trait.

    B-52 APT-50's

    Bob sells one but he will not sell except as a set I believe. I might have a try at making one but my whole drop in K-77 program has been put on hold since one of my best friends has been hovering near death for a couple of weeks now. He is out of the hospital finally so life just might get back to normal.
  15. I have a pair of KP-250 II's and while working on them today discover some differences. One crossover is marked KP 2.5D and the other is not marked at all. In one place one has a 2.5uf cap and the other has a 3.5uf cap. The only schematic I have found online is not the same thing and so I am left to try and figure out what is correct or just replace things as they are and assume there was an unknown reason or they just ran out of correct parts to use in Mexico that day. The closest thing I have found online to this has a 47uf vs 33uf on mine and the online board has no 4uf or 6uf caps at all whereas my boards have one of each.
