    This is the Paudio pht-409 horn from eBay that people on the forum buy and modify. The horn is an exact fit for many Klipsch speakers like the KLF 20/30, KG series, etc. I have an extra set that I never got around to using before the family came along. It has the center diffuser removed already. This was going to go into a second pair of KLF 20's I had, but I sold them before I got around to the project. (I also have the B&C DE 10-8 drivers that I was going to pair with these if you are interested) If you check my posts in the technical/modifications section, I showed step-by-step documentation on how to use the horn and driver together. Located 60511 southwest burbs of Chicago Asking $20 Local pickup preferred

  4. Superelliptical tractrix horn for tweeter - a.k.a small rain from a big cloud. Why a.k.a. It took me several years to actually implement this idea and originally I was planing it for 400Hz horn. I started to think about it in Forte days, I was planing to build some external mid/high horn for fun. Then as replacement horn for La Scala. Original material suppose to be something else. Don't know English name but I was planing it as cast made of polymer resin with mineral filler. Friend of mine was doing round horns with it and I really liked the product. So as I said got idea maybe 5 or more years ago, I did math, CAD project and laid it into a drawer for a long time. Doing large horns is really challenging. Inspired by Dave A work on tweeters I thought why not try something much smaller fist. So I ended with small solid beech wood tweeter horn instead of huge cast resin one. OK so why Superellipse? It's fun curve. Special cases of this curve are circle, ellipsis and in the end rectangle. By manipulating basic curve parameters we can do smooth transition from circle to rectangle or in this specific case rectangle with rounded corners and all the way be compliant with Tractrix horn flare. Why to bother when we have elliptical horns? Because using same front area we can make horn with lower cut of frequency without having any sharp edges on wave path. So basically join elliptical and rectangle horn strong points. Of course it's not always desirable to have lowest cut of freq but in this case math looked good. I have created parameterized xls sheet witch which I can control how transition from circular throat changes to semi rectangular mouth. Horn is calculated for 1544Hz and has good loading from 4147Hz (strange tails but I was shooting for particular mouth size) For this particular horn for half of length it goes smoothly from circle to ellipsis and then shape starts to be more rectangular. But this is fluent and I could make it almost rect from the beginning. From math I did FreeCAD project (or actually my xls almost generates it). Then I had to find someone who will make wooden prototype. It's not so easy to find someone who wants to play with such "large", 4 items, orders, but finally I did. As always with prototype not everything is 100% correct so cut off is probably bit higher but as proof of concept it went well. I stained it little bit and painted with semigloss lacquer I decided to use B&C DE120 for it. Guess I was not reading too carefully because to use it I needed to scrap some wood from top hat to fit drivers magnet. I did some measurements to compare K77 square, K77 round in original horns and DE120 to mine. Looks fine. Green is round, red is square, blue is DE120. Don't pay attention for reference level, my mike has +3 or more dBa from 16kHz but as reference to other K77 measurements it's fine. Currently my system plays better then ever. Unfortunately I cannot say it's all because of horn/tweeter change. At the same same I went from passive to fully active system. So currently I'm using active digital crossover (Najda DSP) with 6 channel Rotel amp. Additionally to normal crossover points I did full time delay alignment for all drivers. With everything changed I really love to listen live recordings. For good realizations it sometimes gives me an illusion of being actually there at time of a concert. Now it's time for bass extension with La Scala bass reflex mod
  5. Location 98312 Bremerton Wa. This listing if for the grills only, 125.00 plus shipping and fees. Below you will find other items as well. 1. Lascala bass bin braces from Volti Audio 2. Jbl 2426j compression drivers 3. K77 tweeters orig coils Having first upgraded (then sold) my Lascala, to move on to Belle, ive upgraded (altered) the Belle now and have for sale some items left from both projects. For sale here is a set of the top hat frames from Belle. Having gone with new ones, i simply dont need these any more. I WANT to keep them, but... anyway. They, and the grill are in orig and Ex+ condition. Felt compelled to offer them here first. Quite literally, these are in Ex cond, no snags or dingle balls, emblems are included. I also have JBL 2426j drivers (new JBL diaphrams) 16 ohm., as well as bass bin braces for the lascala (with lower grill covers to hide the braces) from Dave Harris (never installed) My ability to ship, is second to none.
  6. I found a pair of CF3s, version 1 on shopgoodwill.com. When I hooked them up I found that one of the tweeters crackles at any dB level. I pulled the horn out and detached the driver but couldn’t tell anything from looking at it. The diaphragm looked good and I couldn’t see any damage to the cone, though it is really hard to see anything. Any thoughts? Any way to fix or replace it? This is my first foray into Klipsch and high quality audio so your help is appreciated
  7. this pass Saturday I drove from indpls ind to ocean city Maryland to pick up my pair of 1980 khorns it was worth the drive!!!!!!!!!!!!!
  8. *A L L S O L D * FOUR (4) H E R E S Y ii (consecutive serial #'s) in B L A C K S A T I N $700 per pair ! Speakers are in nice condition ! (see pics)
  9. 1. In simple terms, how exactly does a tractrix differ from an exponential horn in its design? 2. Also, what might be expected if the exponential horn from an earlier Heritage series driver were switched out with an equivalent Traxtrix version? From a listener's point of view, are all frequencies equally affected? (I'm particularly interested in hearing from anyone who has experienced this). 3. Anything else of interest?
  10. I am repairing a built in home stereo system that uses Frazier speakers in every room. Each speaker is a 12 x 12 x 16 cabinet with an 8" woofer and a 5 x 7 tweeter. The tweeters are the black bell type with alnico magnetics. The tweeters are blown in at least 2 of 12 tweeters, and there are at least a couple more. Knowing that there is a lot of common driver parts between Klipsch and Frazier, I am posting my questions here and in the Frazier sites. Checking the internet I cannot find any diaphragm replacement kits. Are there any available? Next option is I have found some 5 X 7 Frazier replacement tweeter assemblies at a decent price, but the magnetic arrangement is different. Instead of the tall small diameter alnico style magnet under a plastic cup, it has a short large diameter magnetic and no cup. The tweeters are marked on the back with: Frazier F-3x7 N4850-F 114850-F U.S.PAT. 3,898,393 Are these equivalent specs? And what are the differences? Thanks in advance

For all details please write me at anton.dedikov@gmail.com
  12. first post here. let me start this off by saying that i recently went from running an old carver receiver and some nht bookshelves to completely upgrading my amp/pre amp to a pair of welbourbe lab mono block 300b amps and an EAR 834 L Deluxe amp. I found myself in a sudden need for much more efficient speakers. I paired the tube gear with some heresy 1's. I bought all this gear in a week on a road trip back home. i spent a few days staying with a friend where we had everything set up and it sounded amazing with the heresys on the floor in a small room. after finally getting them set up at home they don't sound nearly as good. I've tried a lot of different placements but just not the same. the room they are set up is also small. i tried on the floor and with risers. too make things even more complicated, I'm moving in 2-3 weeks into a loft style place with cement walls and a rather large room. will they hold up in an environment like that? should i consider cornwalls or something else?where they are currently set up i seemed to lose some low with a slightly more harsh high end. thanks guys!
  13. What was the best tweeter of the: -1950's? -1960's? Altec, JBL, University, Jensen, EV....in your experience, what was the absolute BEST tweeter in terms of clarity, accuracy, upper range extension, construction quality and reliability? Thanks in advance for your thoughts. Best, Andy

    DIY sub

    I am going to be building a Home Theater out of our 2 car garage soon, and I am thinking of building a new sub. This is what I am thinking of: 1. Build out the garage wall 5' deeper, and 17' wide with a 8' ceiling (garage door will become a screen wall with my 3 La Scalas and 2 Heresy HIPs behind a AT screen). 2: The garage and new room will be double wall constructed with 1 layer of OSB, 2-3 layers of sheet rock with Green Glue. The ceiling is currently 9' and will have about a 6" thick additional ceiling due to 3 layers of sheet rock and Green Glue. What I am thinking of doing is using the whole addition room for a IB type sub but make the exit point of the box into a horn. I would build boxes that would enclose the 5 front speakers and seal them into the front wall. The front wall would only have a hole in it for the sub/horn to exit the room, and the AT screen would conceal the whole affair. I currently have the PSA Triax sub and it is great. I figure when I move to the larger room I will need more subs and I would like to have a sub that will give me the low frequency performance of the Triax (or better) without using a 4000w continuous 8000w peak amp (x2 if I have 2). I would like to be able to do it with a single amp of under 500w if that is possible. I was looking at building dual Gjallarhorns, but I am thinking that this might be easier to build and give me the same performance.
  15. Hi, i would like to extend my Klipschorn stereo setup to a 5.0 surround system . What center speakers and surround speakers would be a best fit ?
