  1. Allow me to rephrase.. if I had a larger house I’d be and even *worse* speaker hoarder!
  2. I wanted to take a moment and close the loop on something from waaaaaaayback in the beginning of this thread regarding the Ta2020 Lepai amps. I had to take mine out of service after a few months (years ago now)... as I found that the output inductors were getting super hot and the ceramic was actually darkened (read:cooked!). Not sure what happened there... but I can't in good conscience say the output mod I did is safe. I know its ancient history - but if any of you folks run these and have done my mods - PLEASE check your output inductors for signs of overheating!!! Again - sorry for not responding sooner - I had completely forgotten about this project until I was going through some old threads and remembered why I stopped using them..
  3. Last night I went through my old posts here - and I got my last set in 2011....sold them the next year I believe. Since then I went through Magnepans, EV Sentry's, RF3's before I realized my true love... So, while the search has been around 5 years or so.... in truth - its been nearly 8.... If I had a larger house, I'm sure I'd be a speaker hoarder...
  4. If any arm twisting was done - It was by me, I'm sure... DizRotus likley got sick of my begging..
  5. I'm blaming you in advance for my loss of sleep tonight! My 5 year search is at an end!
  6. Don't deal me out juuuuust yet - Kevin just PM'd me and I've sent him some ideas...
  7. I have long thought it would be fun to open a second hand high-end audio shop and make a living searching out these gems... well, fun or maddening I suppose.
  8. You have a pm... shaking some trees to see what I can do..
  9. Only way I can imagine would be very labor intensive - the same way they remove dent's out of Brass trumpet bells... very involved process. But then you have to remove the driver and refoam..
  10. Not sure how you guys do this stuff - I'm getting better at the woodworking side - but man.. this destroyed my back!
  11. +1 to that! Also - I’m now Deshelled and enclosed... 5 hours of work.. sealed the joints as well.. next will be reworking the top hats and some paint in the interim.. Pics to follow... but I’m sure some will wince in horror... also so very glad I didn’t sell - the shell disintegrated when I was moving them... I’d have hated to have someone else inherit that..
  12. Kevin - Looking at your pic again - Now I think I may flip my tweeter and midrange vertically when I redo the faceplates.
  13. SCHWEET!!!! Yep - thats tha stuff right there!!! Nailed it!
  14. Dude... CAPS? U MaD bRo? Why not answer the question instead of jumping in and dog-piling on the dude who clearly doesn't deserve K-Horns in his tiny room? I have already stated the following: 1) the custom cabinets on these are HUGE - at least a few inches larger on each side than stock K-Horns.. So - I'm removing them. 2) In the process - I want to be able to toe them in to adjust the soundstage and pull the sweet spot out from the wall. For clarification - the current setup has PLENTY of bass... I never said I had an issue currently. What I did ask, which was the purpose of the entire thread: 1) How much bass falloff can I expect if I proceed as stated above and 2) how much if any difference would the illustrated types of back panels contribute to said falloff. Once again with feeling: I'm not looking to gain anything other than placement flexibility and space... I'm happy to compensate for a nominal falloff in performance via EQ... I simply am wondering if anyone has any actual experience and can tell me to expect a XXdB reduction below XXhz...
  15. Cool! Sounds like you live near where I work.. I’m in Auburn hills near I75 and 59
  16. Have you been stalking my youtube channel...? My only claim to limited youtube fame is a set of heavily modded Tripath amps (Lepai) I was using with the Lascala's back several years ago... Truth be told - other than the lumber - there isn't much that is Klipsch in these anymore - all the drivers are from Crites as are the X-overs. I was looking at DaveA's walnut tweeter horns - be still my heart! I was already contemplating going with a Walnut panel for the midrange and tweeter horns.
  17. hehehe - you are right - the "sweet spot" was about 6 foot in front, and about 10 inches wide... if you moved your head from side to side you would hear the falloff. I love the Magnepan design and theory - but the laserbeam sweetspot I can't get past. (Had MMG's as mains for years in my living room). I'm thinking about trying that for sake of space and then checking the room with my DEQ2496 to see how the bass performance is.... I can always recut the back panels and extend them later... or compensate in EQ if the falloff isn't too bad.
  18. Hijacking my own thread - because I just can't let it go.. This notion is just so common among Hi-end audio forums... the whole "You can't do that in that space" mindset... and by the numbers, sure - I understand. But here is the question - if this is your only option, albeit not optimal - would you really go without experiencing amazing speakers just because the consensus was that your room was poor for the setup? I have enjoyed (and currently LOVE) all my setups. I'm just looking at ways to optimize - I'm an engineer - its what I do - I take stuff apart and change it, mod it, and sometimes put it back the way it was... and sometimes not. That's the fun of the hobby for me.
  19. Just because I find this so amusing - You would die if you saw what I've had in this space in the past... Full Size Magnepans: Magnepan MGII custom stands by Christopher Purdy, on Flickr Electrovoice Sentry's: Ev sentry by Christopher Purdy, on Flickr LaScala's: Untitled by Christopher Purdy, on Flickr The Sentry's were the monsters of the bunch...
  20. Ohhh LaScalas used to live here - and they were AMAAAZING... But in my stupidity I sold them... The absolutley *do* work in the room... for me. Only reason I have the K-Horns is because I got them at the right time for the right price.... and figured I'd give it a go. They do sound awesome in the room - but you are correct - the "sweet spot" is very tight. Let's agree that some people will not find this setup to their liking - and that's fine... but that's not the purpose of my thread. Now - instead of all the things I can't or won't do - I'd like to understand the issue at hand - bass falloff with various back panel types. Bottom line - these puppy's are getting modded and I am trying to decide the best route to take.
  21. ..anticipating some other questions... The other reason for this is that these are Decorators in custom cabinets - approx 3" wider and 4-5" taller than regular K-horns.. To save space I'm planning to pull them back out and ditch the cabinets, and add sides and tophats that are a bit smaller than standard height. I figured I'd enclose the backs while I was at it so I could adjust the stereo image as its such a short wall.... ....and that brings us to this thread...
  22. Yep - I've seen that referenced before.. and I get it. Trying to salvage my K-Horns and not sell them - but also want them out of the corners and don't have room for the full 48" extension... For reference if you haven't seen my other thread - this is the space I'm working with: Untitled by Christopher Purdy, on Flickr And I know - sell them and get LaScala's - yep - that would be my goal....but I'm stuck for now. What I'm wanting to know is - are we talking about losing bass below 40Hz? 50Hz? I am actively EQ'ing so I can compensate somewhat..
  23. My bad - I meant "C"... to save some space.... trying to type and put this together in between jobs at work...
  24. I know the "enclosed back" K-horn topic has been discussed ad-nauseam - so I apologize in advance... but I haven't seen a clear cut answer to this question. Referencing the image below - anyone know or have frequencey falloff curves for some of the following closed back configurations? A - Area 1 - Current K-Horn bass bin footprint - similar to the newest model B -Area 1+2 - Adding some extension, but not a full "false wall" C -Area 1+2+3 - Same as above, but extending this flush with front face D - Area 1+2+3+4 - Full "false wall" extension that stops at the plane of the front face. I'm leaning toward "C" to save on some space, but am curious as to how much loss there will be. (Corrected... I had said D, when I meant C)
