  1. I re-capped with caps from Bob Crites, so I should be good there.  I'll try and get pics to show how they are positioned and some other shots of the room too.   Did some testing a couple days ago using my Denon with an Emotiva UPA-2 amp and using the graphic EQ and some tone adjustments I  brought some better sound out.  Oddly enough if I stood at the farthest point back on the right side about a foot towards center I found the best bass.  I was the only place in the room I felt I had what I was looking for.  

     

    So could it just be my room?  The front wall is 16ft across, the room is 22 ft deep.  The right side up front has a 5 ft wall that then opens up wider about another 3 feet.  That right side wall is just sheet rock and framing with nothing on the back side.   Is it my weak wall?   The other side is sheetrock against cement foundation (basement).   Should I fortify that right wall or maybe consider heavy false walls as shown in the Dope from Hope.  Maybe I'm losing all my bass into the room somehow and false walls would project the low end more effectively out into the room.   I open to all options, its a music room only an no one to shut me down.    Maybe enclose the backs with some heavy 3/4 plywood?

     

     


  2. So I had already removed the ST70 from my Khorns downstairs and hooked them up to my Cornwalls in the living room before I had a chance to switch speaker wires and try them to see if they were out of phase.  With the Cornwalls  the amp plays great, full rich sound with plenty of volume.     Now I'm really stumped why the Khorns sound so thin, they really have almost no bass.    Should I open it up and inspect the woofer, maybe it has an issue?  These are 41 years old.     Maybe the speakers themselves are wired out of phase and are cancelling each other?   


  3. The 16 ft wall is my only option due to the layout of the room.   I had Bob Latino build mine with upgraded caps does that mean I have the Russian PIO caps?    

     

    And thanks for the input Wdecho, I didn't think to try that hopefully later or tomorrow I'll give that a shot.  If that doesn't make a difference should I expect that I have a problem with the crossover?  Should I inspect the woofer and what do I look for and test for?

     

    Thanks


  4. So I bought an Emotiva PT-100 preamp and hooked my ST70 up to my Khorns which are in my basement in perfect corners but the floor is carpet over cement.   I still only have about 20 hrs on the amp but I have very little bass.  I've cranked up the bass adjustment and its still weak and totally not good enough.  

     

    I hooked up my THTLP sub and of course it was great but I just can't believe my Khorns sound so bad without a sub.   Is it the cement floor?   Is it the preamp?   Is it the ST70?

     

    I have the Khorns spaced 16ft apart in perfect corners and the room is 22 feet deep.  I really expected to be blown away and now I don't even want to listen to it without the sub on.

    I have heard that Heresys are voiced to be on the floor and you will get more bass response with slant risers instead of stands. Personally, I think the slant risers look cool and have kind of a 'concert stage monitor' look to them. That and there is less worry of them falling over.

    This was my experience, if you use risers you will definitely need subs.  The bass disappears when you raise them


  6. So I just bought a brand new VTA ST 70 fully assembled and have about 2 hrs on it so far.  I got the volume control so right now I'm using it without a pre amp.  Right now I'm using it with a pair of Lascalas and the clarity and detail are a major step up from where I've been.  I am a little disappointed with the bass so far, do I need more hours on the tubes to break in?   Bob suggested the el34's for heritage speakers so that's what I went with.  Any thoughts on that?

    Actually, everybody has helped a huge amount!  And I appreciate the patience and information from everybody, it did factor into my decision.  Hopefully I did OK.

     

    First, it was interesting from dirtmudd about the calculations of the Scott amps in today's dollars, I hadn't really thought about that aspect.

     

    There was another problem I kept thinking about, and that is how so many of the tube amps are <10 watts, some even at 2 watts.  I saw the thread from Maynard:  https://community.klipsch.com/index.php?/topic/170414-who-wants-to-measure-how-much-power-voltage-is-really-needed/&

    Now, of course, I don't understand 95% of it, but derrickdj1's comment too, "I have the RF 7 II's and my tube amp is usually under 2 or 3 watts for my normal listening level."  Also, and of course I don't understand it, some say watts from a tube amp are more efficient at actually driving the speaker than the solid state amp.  And many are saying that the first watt is the most important.  So I did finally accept that I didn't need 100 or more wpc, especially with the efficient Klipsch speakers.  The weird thing though is I thought somewhere somebody had said if the speaker is underpowered it could be damaged, so maybe somebody could clarify that at some point.

     

    And, the debate about older but rebuilt vs. new with the warranty was also factored in.  In the end, it is interesting that but for a few seconds, I might have ended up with that 299C which was several decades old, but restored.

     

    So it turned out that I found a used Decware SE34I.5 (Rachael model) within the price range and bought that.  Before I got it he let me listen to it with his system, and it sounded excellent.  Of course, I'm thinking the rest of his setup didn't hurt, as he had everything top of the line and in perfect condition.  I'm not sure about the brand of speakers, but they're supposed to be mighty expensive ones.  He turned out to be a great guy too, either he took pity on a non-expert like me, or he's just happy to help everybody.  One of the factors too is that Decware gives a lifetime warranty, although I'll have to pay a bit to transfer it to me, which I'm waiting on until it becomes necessary.  The guy I bought it from said he didn't worry about any warranty, since the quality was so spectacular.

     

    So I hope I made a good choice, I hope I didn't pay too much, and I hope it will last a mighty long time.

     

    I was looking at this exact model today, new they are about $1500 and he offers some customizing for not much more money.   I'm curious how you are liking the amp.   I'd be using mine to power my Khorns or Lascalas.   I'm unsure if I'll get the bottom end I love with so few watts.  What are your latest thoughts?

     


  8. Saw this thread and thought I'd post here first before I put my ad up.   I have Quartets that I'm going to list here soon and on CL as well.  I'm on east side of Denver if there is any interest before I get an ad together let me know.   Speakers say QUR 00 for type and they have  sequential serial #s,  date of 8-31-90.  

     

    Let me know if there are any questions.

     

    Thanks

    John
