  1. I've come to the conclusion that I am never going to use these but there has been a lot of interest in them with the advent of the Heresy IV. The K704 are from an older KP series though I do not remember which model exactly. The 2510's are the same horn without the 12" woofer notch/cutout... so you'd have to use them in a DIY build or mod them to use them in a klipsch cabinet. $50 +shipping for either pair
  2. PH-2510 = K704 I own both. No difference other than the notch/cutout for the 12" woofer. If you wish to replace the K701/K53Ti in your HIII or CWIII with a K704/DRIVER then expect to modify or replace the HF/MF network. I have a single CWIII that hangs out in my garage for mono duty. A while back I did play around with installing a K704 with a few different drivers just for fun... none of them sounded right or looked right when analyzed. You can swap out the Ti diaphragm for the old phenolic style in the K53. A few forum members have said they actually prefer this to the Ti? I found the difference negligible in my testing.
  3. I have been wanting to see that driver for a while now, thank you. My initial guess would be that, while Klipsch could have a diaphragm made for their use, it would be more cost effective to use the CDX1-1748 as is... and data sheet looks like it would fit the bill without alteration? I've also heard good things about this driver on other forums. I had originally thought the K771 was a B&C DE7 but the Celestion CDX07-1075 does look a bit closer in some images? They could very likely be made in the same plant by a contracted supplier though?
  4. You know the funny thing is that Paudio says it's a diffraction horn? It's hard to see in the brochure but in person you can see where they have filled the woofer notch/cutout.
  5. HIII and CWIII both use the K701 exponential horn w/ the K52Ti (16ohm) driver/motor
  6. Do you have non cropped version of this photo?
  7. As a possibly relevant side note: I am using 315LF's and not 904/940's so according to the active literature we've been discussing I would need to attenuate my HF -2dB, which I originally did when I started playing around with this setup by inserting a single series resistor prior to the + input of the network. I considered this solution simple and effective for what I was attempting and this method appears to be commonly used in current Klipsch networks. As an example this Jubilee/402 network supplied by Roy allowed the owner to insert a value 0-4ohm (0 to -3dB) inbetween the network and the K69A driver "to taste". In any case, I found that the -2dB suggested was not quite enough and end closer to double that using a 5ohm resistor. This experiment would make me wonder if those using the 904/940LF might not want to try using a 1-2ohm resistor (-1 to -2dB) in the same manor.

    That would be my take away as well. Visually all the mumps do allow the horn to more gradually transition from its conical throat, appearing somewhat elliptical toward the middle, to it's rectangular mouth. A minor change but the devil is in the details. And again, I'm not questioning whether or not it is better, I feel like that is a known. I'm more questioning whether or not it is worth the hassle of buying a whole new set of KPT904HF's ($$$) just for the K510M's.

    There is a quote out there somewhere where it was stated that the H4 horn doesn't have mumps because "they weren't needed"... And my personal opinion is that that horn is so limited in scope to begin with that mumps wouldn't do anything for it? So I can understand Klipsch saying that.
  10. Actually the 335 has an LCR in the MF circuit that is centered at about 3650kHz as well... I wonder if Roy would ever consider supplying 904 owners an LCR design, that could be inserted between the supplied passive network and driver, that could be used to tame this issue?
  11. I've noticed it too but can't isolate it... The high Q value and distance from the crossover point make me think it is whatever is causing "PEQ2: 3.7kHz Q: 5 Gain: -3db" in the active settings. Surprisingly the KPT-Grand HF-T (510/69) similarly requires "PEQ4: 3.5kHz Q: 7 Gain: -2db" "PEQ2: 3.8kHz Q: 5 Gain: -3db" in certain applications despite being crossed at roughly 4kHz in those applications

    While I'm sure the 402's are VERY cool... I would need to be able to fit them in my home to enjoy them.... same reason I've never owned a Lascala or Khorn

    Actually, EQ does help... which kind of makes sense given the intended application of an KPT/KI speaker. And speaking of driver selection... in a long (over 10yrs ago) dead thread, @Chief bonehead made a reference to producing a network designed for a K-510 with a K-69-A driver but I have never come across it. Does any one know if this said schematic exists? All, I've ever found are the 2 schematics for the Jubilee w/ the K402/K69A
  14. CANT


    Yes, it would be good to know that as well.
  15. Thanks, unfortunately for me, the sale continues...
  16. The K704/K704T is not really a direct drop in replacement for the K701 though it does share the same mounting dimensions/flange. It takes some network tweaks to flatten it out. The PAudio 2510 horn is identical except it is missing the woofer cutout/notch. I have a few of them that I have tried to use a few times but they never sound very good... I have avoided all of the stock models that utilize them because of this so I do not know how the current implementations sound? As for the driver, I am also curious about what it is exactly... my current guess is the same PAudio driver used in the KPT/RF/Forte just with a new diaphragm but it could be all new?
  17. Has anybody opened one of these up yet? I'd really like to see the K702 driver... I'm guessing it's just a K70G/K701G with a new diaphragm but maybe not? Also, though I'm not sure why anyone would want to, there is a very good chance you could easily 2way a CW4 using a KPT310M crossover.
  18. I mean, I tried it too so I don't really have that much room to talk but I would suggest erring on the side of trusting Klipsch... If they could have extended the freq response, without consequence, just by adding some cardboard tubes I think they would have? I threw out everything after I was done playing around but what I remember was that while adding length extended the response it also decreased the output under something like 100Hz. Maybe if I played everything at concert level I wouldn't have noticed but at moderate levels it didn't sound right. Does any one who has done this mod have before and after data?
  19. Ok, I'm going to go a head and open this back up now that the holiday madness is over... Both of these are packaged up and ready to ship. Both boxes are 12x14x17 & 22lbs. They are technically shipping in the original boxes though they are now at least 50% boxing tape. When I ran quotes for the guy in NV it was looking like is would cost $50ea to ship them. I'm not sure if that was because of where he was located or because it cost more to ship something around Christmas? It was definitely higher than I was expecting...
  20. Before giving up on the CWII’s try replacing the tweeter diaphragms with the current Ti version. You can buy them directly from Klipsch. They don’t cost much, less than $100 for the pair. Whole tweeter assemblies are also available if you don’t want to disassemble your current tweeters, they are like $100-110ea if I remember correctly? I had to buy one a while back... If you want to test the waters before purchasing parts just remove the tweeters from your HIII’s and install them in the CWII’s. There are other mods/updates you can do but in my experience the tweeter diaphragm is the biggest... if you don’t like them after trying it then you must just not like them
  21. I played around with adding port length to my KPT315LF’s, which if I remember correctly have a similar volume and port design... none of the results I saw lead me to believe that this is a mod worth performing
  22. I currently use a Marantz NA7004. It’s technically a media streamer/player but I really only use the opt and coax inputs... been very happy with it for quite a while. I think the current iteration is the NA6006?
