The center HP640 with the EV DH1A driver did not sound right with the K402/K-691 for LR, but matches up much better with the B&C. I plan on trying a couple more horns to get it just right but the B&C seems to be the same driver as the K-691. Unless Roy is doing some kind of phase plug magic to the K-691, it's more than likely a B&C driver, unless of course he cut a deal with Celestion for other drivers besides "the Big One."

Paducah Home Theater Posted November 11, 2021 Share Posted November 11, 2021 We have more trouble with shipping these things than anything else. It's not just our carriers, we've had them damaged from Klipsch to us more than once. Just very fragile with literally zero internal stuffing of any kind. The box just collapses and that's that. Even if they don't stack stuff, other customers tend to try to ship tall items and don't strap them down or whatever so stuff tends to fall. Doesn't take much and you get a shattered 402 horn. All we can do is deal with the fallout afterwards. Either that or spend like $700 a shipment to rent an actual crate and pay for the extra weight. Unfortunately it's just one of those things where you have to risk it, there's no good answer. 1 1 Quote Link to comment Share on other sites More sharing options...

To each there own I guess. 🙂 Why not grab some tape, cover the holes, and see for yourself? Two or three weeks should be long enough to see if you look at your 402s any differently with the unused mounting holes covered. Size is likely a factor in this mysterious area, since the 510 horns didn’t seem to cause the slight discomfort that the “holey” K402s do. YMMV (Your Mind May Vary), of course. It could also be a sense of incompleteness that we’re seeing with the unused holes showing. Something nags at us faintly that the job is only 99% finished, that something should be be bolted onto those flanges, but we’re not sure just what. Roy assures us that an extended baffle is unneeded when these horns are part of a pair of “underground/original/Pro Theater” Jubilees, or Jubescalas/JuBelles, etc., so that can’t be it. Some folks may feel the “room dominance” effect, some may feel the “incompleteness” effect, some may feel neither, while some folks may feel both. In any case, this is something that can be quickly, easily, and cheaply fixed. How often do we hear those three words in a description of a speaker tweak? Go for it! 2 Quote Link to comment Share on other sites More sharing options...

I've been hankering lately to drive up there ......for lunch (Chesters in Hamilton) If I did that, I'd be happy to bring it with me and let you do a side by side for an hour or so... (perhaps just enough to whet your appetite??) While you're salivating over that, I'd be stuffing my face with Chesters... Let me know when you are coming up. It would be pleasure to meet you.

NBPK402 Posted November 11, 2021 Share Posted November 11, 2021 I followed your suggestions and put in the plastic plugs. Aesthetically they are more pleasing. It is subtle but a just different feel in the room. Or maybe I am imagining it, perception bias and all that. YMMV.You could always get some sticking black velvet to attach to the flat face...might even help the sound.Sent from my SM-G985F using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Just very fragile with literally zero internal stuffing of any kind. there is one way , which is to use a foam padded box for the K402 , either injected foam to fit , or the foam types found in computer servers , it could also be cardboard molded type protectors that cover both halves of the horn yes it's gonna have to be a bigger box , but it will also be a safer box , and way less damages or insurance claims , RMA's .....paperwork-plus the stress - if the horn is busted using foam boxes or molded cardboard boxes , then , you got a carrier problem ---versus a horn packaging problem - Finally, klipsch can also re-manufacture the K402 horns with a wall thickness of 0.6 inch to increase the resistance of the horn to impacts - 2 Quote Link to comment Share on other sites More sharing options...

It fit into the foam pieces like a glove. And it was very stable inside that box for transportation. 1 Quote Link to comment Share on other sites More sharing options...

You could always bolt a 510 assembly to your horns like I did. That cuts the unused holes to 6. What's a half dozen holes among friends? I have to say I have had 402 horns for a really long time and I never looked at the holes. It's usually somewhat dark in my room. But I'm not a hole looker I guess. Quit looking at your horns man, your going to have an audio nervosa breakdown. 2 1 Quote Link to comment Share on other sites More sharing options...

I am still in the process of reusing the plywood in other projects. Good thing I have forks for my skid steer so moving them from the end of the driveway to the audio room was easy.

I would love to hear a set of Celestions with and without Roy's phase plugs. I can tell you today if I was seeking a new set of 402's with 1132 drivers I would buy new from Klipsch. I have had a chance to do direct comparison between the old 1132 style phase plug and the new ones side by side. The difference was not subtle.

I still think the K1133 drivers are better, and with your sMAHLs, the K-402's are even better! The 3-way version of the Commercial Jubilees (now called Undergroud) sounded better to my ears in Hope. I think the new Jubilee is like a 4-way system, using PEQ. The phase plug, spreads the highs Wider in the K-402 (what a great idea by Roy), and the sub bass is taken care of by horn loaded bass ports. None of it could be done without bi amping and PEQ, which is a great use of modern technology that PWK never had when he designed the Klipshorn.

Something that PWK did not think was important. When you consider the 45 degree toe-in of the Khorns, having the tweeter blocking the central part of the output on a K-402 will have very little sonic consequence since, physically, it's so small compared to the mouth of the mid. 1 Quote Link to comment Share on other sites More sharing options...
