    Hooked on Ebonics La Scalas

    in Alerts!

    Posted

    Many thanks to DizRotus - the LaScala's are now safe at home! 

     

    The work has begun to clean them up after 42 years of use and neglect.  Lots of love is going into them now - and glue, wood, new drivers, crossovers... 

     

    Not sure how I will finish them in the end... likely I'll fix all the laminate issues and paint them for the time being.  Possibly veneer down the road if I want to experiment..

     

    From the model / serial number (LS-BR, 10R195) these are Raw Birch, from 1977.

    chip amps: Almost everything you ever wanted to know

    in 2-Channel Home Audio

    Posted

    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..

    If he has been looking for five years, you did him a great service.

     

     

     

    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...  :P

    The stars didn’t align for @Escher, so I now own these. As I told Escher, I’m not worried about getting back my “investment.”   First I’ll clean the Crown amp and preamp to see what they can fetch on eBay.  Then I’ll try to move the La Scalas to their next custodian.  

     

    First I’ll try to find a buyer who wants them as they are to restore.  Failing that, I might restore them as a summer project before selling them.  “As is,” finds all drivers work and they sound OK, despite antique AA networks.

     

    Please don’t be shy about expressing an interest in the La Scalas or the electronics. I can always find other projects.

     

     

    Don't deal me out juuuuust yet - Kevin just PM'd me and I've sent him some ideas...

    What's wrong with your original setup? The way I see it from the photos, you ALREADY have 4 feet on each leg; it just so happens that they "share" one leg.

     

    I don't see where you'd gain anything from building external walls.

     

    Your  bass limitations are due to your room dimensions, not the position of the Klipschorns, and I don't imagine building external walls will improve things.

     

    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...

    Once you enclose the backs, like Dean said, you will have the freedom to toe them out, like the LaScalas. The Knorns take up way less floor space than LaScalas. Once you have done all this, then putting DaveA's MAHL super tweeters in the tops and going for a 3 way Xilica active Xover with some Chinese chip amps will do the trick.

    Have you been stalking my youtube channel...?  :P

     

    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.

    Of all the speakers you've shown so far, the Maggies have to been the least suitable.

    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'd be inclined to go with just "1" like the current factory-enclosed model does. 

     

    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.

    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.

    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.

    ..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...

    I had 2 false corners identical to the ones Paul Klipsch had in his home. He said anything beyond 4 feet from the corner wouldn't make a "dime's worth of difference" when I was at his house listening to them. So the 2 legs of your triangle should be 4 feet with a height tall enough cover the bass bin height. I just cut by plywood sheet in half to make 2 4x4 foot (48x48 inches or 1.22x1.22 meters) pieces for each false corner. Easy to do.

     

    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:

    43338214962_2c1a293abb_c.jpgUntitled 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..
