  1. Big thanks to Tom for making this easy and good price on great equipment. My plan is to use the The K510s as surrounds in some way in the basement HT. In the meantime I had to try them out naturally. I thought my TADs were huge. These JBLs are monstrous!
  2. Finally got around to replacing a K48 equivalent driver that my FH1s had with a Kappa 15c. Very surprised how close the drivers are in this horn and not just one horn sample or driver. Here are the raw measurements in REW. Red is the K48 driver one FH1 came with and green is that same horn with a new Kappa 15c. Blue is the other K48 driver in the other horn. Amazing how close they all are.
  3. I've got a MiniDSP 2x4HD on order to use with them instead of the Xilica soon. It will allow a high pass lower to keep most of the 15-20Hz subsonic goodness that is a primary strength of this horn. Not that I'll feel that very much but for movie LFE I do like to demo the opening of BladeRunner 2049 and Edge of Tomorrow which pressurize and shake the house nicely! Current amps driving the DTS-10s? Hypex NC400 monos (from kits) which may be underpowering them a bit at about 400w/4 ohms.
  4. 1st try at some EQ with a 20Hz high pass to protect the drivers and a big cut at 56Hzin the Xilica 4080.
  5. Being the same model and about the same distance from my PLP they sum nicely with no intervention but the design has that well known 56Hz peak/resonance.
  6. Interesting use of the Jube backs to extend the SPUD horn. This thread and especially that video got me off my butt and integrating the 2 DTS 10s I acquired earlier this year. Because of my room dimensions the left one works best to the outside of the Jube as a corner extension but the right one may be able to have its mouth in the corner and use your extension trick. It's been fun breaking out REW and the UMIK-1 again this past week and measuring/seeing how these 2 monsters behave in my room.
  7. For Locomotive Breath I never paid that close attention but now I'll never "unhear" it. Looks like others report it alright: https://discussions.apple.com/thread/979988? and in the Steven Wilson 5.1 surround mix: https://www.quadraphonicquad.com/forums/threads/jethro-tull-aqualung-blu-ray-audio.15133/page-2 Here's a brief "fair use" excerpt of just the left rear channel of the SW 5.1 remix of Locomotive Breath where I first hear the "distortion" I think we're talking about. The bass line is very propulsive and on the beat but at about 13 seconds into the excerpt goes from a relatively clean bass tone to a fuzzy, buzzy more distorted one. Intentional effect after the distorted guitar? https://drive.google.com/file/d/10TKL-E2NataqKcUf_D34AZK8DkQTZ1QL/view?usp=sharing
  8. there's a budding audiofool right there at the window. Play some bird songs. Or maybe jazz like...(wait for it)...Donald Byrd. Kinda how I felt as a poor college student looking in the window of the local hifi shop at Khorns!
  9. Looking good Ron! No doubt it sounds entirely different than the no cabinet version with the back waves of the woofers enclosed. What did you do to absorb that back wave? Line the cabinet with something? As far as your partner not liking the large protruding black horn, how about an automotive finish in her favorite color? Might be easier than trying to get a complementary faux veneer never mind a matching one.
  10. thanks for clarifying that Chris. Sounds like my FH-1s might be good to try with an AMT-1 double-stack
  11. Hmmm, I'm surprised the Peavey has the narrowing polars you describe since it doesn't have the flat baffle in between the two mouths.
  12. As far as I'm concerned you've got the point of this thread completely Rick! Have to admit I don't get yet what you're doing with the "tablesaw gymnastics" but I appreciate that you're trying to evolve the design beyond Chris' initial build and paying close attention to fit and vibration control. Keep the pics coming!
  13. Just ordered a 3/4" BB 5x5 sheet cut in half from Makerstock for $60 and $15 shipping to my home. It was a bit difficult to place the order as their automated shipping calculator kept saying that the 60x30 or 30x30 pieces I was choosing couldn't be shipped to my address but C.S. Amy helped me out. Will report how that works out...
  14. Hmmm, got me wondering. The K-402 horns are delivered by Klipsch in several arrangements without the mouth attached to anything and in at least one case fully attached and in a box (KPT-305). Are there significant differences in sound quality due to resonances for unattached mouths? What is it you are beginning to hear exactly? It is an appealing idea to my logical mind that the horn would resonate coloring the sound left undamped/not very stiff or rigid and mouth unattached, but, what seems logical ain't necessarily so! and...even if this could be proved to be the case the question remains at what level of magnitude is it happening - in other words is it audible? One thing I know in my following of ChrisA over the last years is that measurements with a calibrated UMIC-1 and REW and the subsequent iterative dialing in of my speakers based on the K-402 makes a huge audible improvement! So, clearly adjustments based on careful measurement do work. We can correlate sound which the mic/software measure with what we hear. I wonder if the UMIC-1/REW combo could measure any resonances of the type postulated? I propose this test. Tell me if you think it valid. Hypothesis: The K-402 horn playing midrange and high frequency sound/music with mouth unattached resonates so as to color the sound/music in an audible way. (note that this test will be confined to midrange and high frequencies so that it may be carried out on a K-402/CD combination prior to any MEH mods.) Setup 1: A third generation (thinner) K-402 with TAD-4002 CD will be mounted on its Klipsch stand (attached to mouth at 2 bottom holes only) and placed on top of a Jubilee bass cabinet in a corner of my living room with the bottom of the horn at height of the bass bin - 40 inches. My calibrated UMIC-1 will be mounted on a tripod with mic capsule at 45 degree angle and the tip at height of 54 inches - the middle of the CD at a distance of 3 feet from the horn mouth. Plentiful thick fuzzy absorbent material will be placed on the floor between the horn and the mic. REW sweeps will then be recorded from 400 - 20k Hz going back and forth several times with ChrisA (if he's willing) to get representative measurements of this combination. Perhaps varying the sweep volume in an attempt to excite measureable resonances in the horn - (not the room.) Setup2: The very same K-402 and TAD-4002 samples mounted in a KPT-305 box (securing the full mouth flange at all 12 factory drilled mounting points) Keeping other variables of measurement as constant as possible (mic position, dampening placed on floor in front of horn between horn and mic) the same set of sweeps will be recorded. Analysis: The recorded sweeps will be compared looking for differences possibly due to horn resonances.
