    Thanks for the input everyone.

     

    The P-312w does not appear to be available on the Klipsch site. I see some other urls with a Google search where it sells for $2499. That is the same price a the SVS PB16-Ultra - which looks like a lot more sub. My concern with the SVS is the weight: 175lbs - this will hurt if I need to move it.

     

    I have had my RSW15 repaired once (2 years ago) by Edwards Electronics - it worked great for 2 years. I am looking at maybe driving it with an external amp like one of the posts mentioned above. Anyone done this?

     

    Decisions, decisions.

     

     

     

    All of us that have passive subs do it.  Anyone who has built a horn loaded sub uses a separate external sub amp.   I have a THT LP that is powered by a Bash 300 plate amp that I mounted in a wooden box that I built, it sits off to the side of all my other gear. 

  2. Can't you simply buy a decent external sub amp and just run speaker wire into the cabinet and to the driver.  Leave the shitty plate amp where it's at, disconnected and fully sealed.   You will still have all the controls and way better reliability as long as you have room to add one more piece of equipment.

  3. Sounds like the OP has noticed an improvement with the AA crossover versus the AL which he compared pretty much back to back but it doesn't sound like a night and day improvement.  Seems everyone here says how awful the AL's are but can anyone really explain the difference?   I'm on the fence to replace the AL's in my Lascalas with either AA's or ALK universals.  Are we talking like a 20% improvement or is it just some subtleties gained that most people struggle to hear?

    OK; will try it with the amp at 100% and "adjust" it with the pre-amp.

    That's the way to do it.  I have the same amp and use it with an Emotiva PT-100 preamp, I get plenty of volume.

  5. Well finally got it hooked up and it sounds great.  I had a Yamaha A-S801 integrated hooked up previously and it was good, the HK 730 is better.   I really can't believe it sounds better than a $900 new integrated.   The bottom end is better the mids just sound more relaxed and overall it just sounds right.   The HK has more than enough juice to hit crazy loud levels just as easy or easier than the Yamaha which is supposed to have a true 100 watts per channel.   Very happy so far.

  6. The guy just retired and said he was just moving some pieces he had collected through the years.   He had all kinds of modern and vintage audio  throughout his home and said it all works.  He said the oak wood case is super rare and that he rarely saw any even in the 70's when he sold HK's when they were new.  He said if I didn't like it or need it that the case alone could probably sell for about $100 on its own, but I think it looks great and don't plan on getting rid of it.  If I ever decide to part with the receiver I'm sure it will only help to retain the value of the unit.

  7. 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?

     

     

  8. 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?   

  9. 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

  10. 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

  12. 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?
