    Claude,   Do you mean Bob's CT-125? 

     

    Yes, that is what I have in my Super Heresy's currently. I also had a pair of those CT-125's in LaScalas I refurbished, where I dropped the midrange/K55 level on the Autoformer by 3 db to match, since the CT-125 is not efficient enough for a Khorn/Belle/LaScala. It's a really good sounding tweeter and it measures ruler flat to 20K for all other Klipsch Heritage, however.

     

    Huh? Bob sells it as in drop-in replacement for the K77 and you are saying it isn't?

    That 50mm 1.8 is exactly the lens I was talking about. Really a fantastic lens for the money.

     

    I don't use it a lot but it is a great little lens, very sharp, acts like a 70mm on a DX camera.

     

     

    I and everyone knows what you mean by that, but... no it doesn't. :ph34r:

     

     

    If this comment implies what I think it does, we are about to embark on a photographic argument worse than capacitors... :(

     

     

    LOL! I didn't know it was a hot button issue.

    John just likes to see if anyone's paying attention.

     

    Please, I'm really not "that" needy. 

     

    That said, I've had time to work an interesting problem to something of a conclusion and will discuss it on the forum page of my site.  I'll provide the link for those that are interested.

     

    I registered but can't find anything relevant. The 'Engineering Projects and Discussion' section is empty.

    Hey, it's The Doctor - welcome back John. Before I agree with you, I want to know what the green curve is :)

     

    Greetings sir! 

     

    The green plot is something I've been noodling here.  The K77M can actually remarkably good at higher sound pressure levels "if" you use the green curve.

     

    To use the green curve however requires other changes to occur and that's where things get very interesting.

     

    it's possible however to take the Klipschorn to a much better place without having to take a second mortgage out on your house.

     

    More on that later.  

     

     

    Did I miss it?

  6.  A 16 gage wire is a good compromise for size it makes for a good balance of frequencies remember high frequencies travel on the skin ands bass frequencies travel in the wire.

     

    If this partly in answer to my earlier question of why 16 AWG would sound better than 14 or 14 AWG, I disagree.

     

    For cooper, skin depth at 10 KHz is about 0.65 mm which is the radius of 16 AWG.  Are you trying to match them?

    At audio frequencies, pretty much all of the wire is used even at 12 AWG with a radius of 1 mm.  The 12 AWG still has the advantage of a much larger cross-scetional area covered by skin depth (and there's still current deeper than skin depth).

    Wouldn't it vibrate?
    I'm sure it could be measured or felt but not seen. Guaranteed to ouperform a Khorn with one whole side missing, either way. You could make it only 3 feet without sacrificing too much, since even Khorns need subs below 60 hz. anyhow.

     

     

    I used an Ikea tabletop for a few years, one that is about 1.5 inches thick. Worked well.

    They would just take up far too much real estate. As it is a condo all the living is in the living room. If I had the corners they would work.

     

    Up against a wall, you could make 1/2 of one out of a fraction of a sheet of 3/4 Oak Plywood and attach to rear. One corner and one wall for this other one is all you would need. Made my Khorns work in several different homes that way.

  9. Here's a bigger picture.  The black steel tweeter stand is meant to be bolted to the cabinet.  I didn't want to do that, so I had sub-stands made up out of 3/4" Plexiglas.  They sit on rubber knobs, and the added mass helps isolate the tweeters from the cabinet assembly.

    Since the LS II comes in two parts, why not simply remove the top bin and place the new horn on top of the bass bin?
