    I'm finally going to get into Dolby Atmos and purchased a different processor to do so. Also getting ready to buy some  different equipment. Next purchase will be the Magnetar UPD-800 Blu-ray player. 

     

    I have been trying to purchase some Klipsch Cinema Surround speakers, but I'm having trouble finding a dealer.  I have to search a little harder.  I'm thinking of the KPT-12-VB, KPT-8-VB, Kpt-1200-VBM . I need 2 surrounds, and I might use them for 4 ceiling mounted Atmos speakers. Have to see what kind of frequency response is actually sent to the those Atmos channels.

     

    Welcome back Q-Man.  I went Atmos 7.2.4 myself in the basement HT mancave.  My budget is pretty sensitive so I got a lot of bang-for-the-buck from used Klipsch Pro speakers,  2 KPT-110s for side surrounds, 2 KP-102s for back surrounds, and 4 KI-102s for ceiling Atmos.  I mounted the ceiling speakers to an "X" made of 2x4s bolted to the joists in 2 places along which they can slide for experimentation with placement angles.  Just getting it running this week.

    New processor is a used Anthem AVM60 (my 2nd one- also have one in the living room) bought through a local dealer who gave a 1 year warranty.Gadget Television set Television Display device Electronic device

  2. Looks great!  I plan to mount my KI-102s on a 7' ceiling - so even lower.  Did you consider modding the mounting brackets or the way they anchor into the joists so that the overhead pair could rotate and be aimed at the MLP?

     

    Those very different choices of Atmos mixes are exactly two of ones I'll be using for first demos  👍

  3. Good call!  I disconnected the transformer and pulled it out then connected the xover directly to the input cup as you described.  What a difference in efficiency/sensitivity/load on the amp - Aww Hell!  It's much louder!  Looking forward to ceiling mounting my 4 much like you did your 6.

    Yeah, I looked into and quickly ruled out the 70V amp option.  I already removed the input cup and horn on one of them so that I can see what I'm dealing with.  It seems pretty straightforward.  However, I want to ask Roy a few questions about it when I'm at SubFest later this week before proceeding.

    How did you make out with your transformer bypasses?  Get the straight skinny from the Chief?  Turns out my KI-102s have transformers after all.  I paired one with a KP-102 and thought it had a problem until I adjusted the preamp balance and realized that it's just less sensitive than the KP-102.  I had opened one up and found this:

  5. Thanks.   So, would any of the many options for new diaphragms available on ebay, amazon and even from Crites be suitable (mostly titanium) or should I look for "mylar" (phenolic?)  The 3 terminals is just a double of the positive one I believe.  I just have the 2 KP-102s but am thinking I should replace diaphragms on both.  Where to get ferrofluid?

  6. Good to know Geoff thanks!  As I googled in various ways about the tweeter, I thought I’d touched on something P-audio when I started using the term “cross reference“.

     

    I’m curious how you knew about this copy of this Klipsch tweeter.  Are there some cross referencing sources that you go to or better yet one master source?

     

     Oops, maybe discussion of this sort is frowned upon now, because it directs people to purchases other than Klipsch.

  7. Not sure.  I measured the resistance across both tweeter inputs and both working and not working units are at 8.4 ohms.  Besides sounding very "dull" and the problem following the tweeter when I swapped them between the two KP-102s,  this is how I know there's a problem:

    The first two higher level sweeps are the KP-102s.  The red one has the bad tweeter.  I also checked it by disconnecting the woofer.  The "bad" tweeter only made a very low sound during the REW sweep by itself.  Is there a way to measure the diaphragm directly?

  8. By this do you mean aligning the drivers within a system, so that the woofers are aligned with the tweeters? Maybe you mean the left speaker with the center speaker and being sure that that pair is in phase and then aligning the right speaker with the center speaker and being sure that that pair is in phase etc.?

  9. Nicely cared for pair of 1988 Klipsch Klipschorns in oiled walnut. Sequential serial numbers. Bought in 2010 for my then new (to me) home with proper corners. These are the speakers that started my big horn journey. They are equipped with ALK Engineering universal crossovers replacing the stock AK2. The original crossovers will be included. Conservatively rated 7 for age. Selling to raise funds for more audio adventures and because I've moved on to Jubilees. They sound excellent. A bit sorry to sell the best looking speaker I've ever owned.
    For local pickup only in Upton, MA 01568.  I will not ship but can help you load them safely for transport.

  10. Hmm,  I wonder why you're not getting SPL out of the compression driver?  That shouldn't matter whether it's in a cab or not.  After all it has no back-wave.  Interesting that you were getting 20Hz in cab.  Mine drops off a cliff at 50Hz but is otherwise dialed in thanks to Chris A.  I have a Danley DTS-10 for the lower frequencies.image.thumb.png.a95e5cee7d679e77892343723b5a8727.png

  11. "The Mesquite is screwed on and glued to the horn"

     

    The stiffening pieces at right-angles to the woofer mounting plates are what you're referring to I'll bet.  Curious to see how they're screwed to the horn.  I glued mine only.  Are your woofer mounting plates also screwed and glued to the horn and the other pieces or removable?

    Got any construction photos with the woofers not mounted?  I'm very curious to see if or how you did any "frustrumizing" to smooth the transition into the horn.
