John are you just looking for an equation? Am I missing something? More importantly hows come you gets the cool purple star and the "elite member" moniker? Are you the Green Beret of the BB users? "One hundred men will test today, but only John, gets the purple star..." jwgorman

Ok fellas, I'm game...where does one secure these caps? jwgorman

I shall post both a schematic and a photo for all those interested in this mod and would rather see photos. If you're reading along, check the LC sections in your book. All of you who have emailed me lately, I will get back to you soon. I've been extremely busy lately. Where shall I post these photos/jpegs? Suggestions? jwgorman

Lammers, I believe what you're describing is the dreaded KLip circuit. Yes by all means remove it too. The coil/cap circuit (an eliptical filter in my electronics 101 handbook) is a different beast but equally nasty for those with modern tweets. JWG

The unofficial mod list: All K-horn's,Belle's and LaScalla's that have networks newer than the AA type will have the eliptical filter and will benifit from the removal of same(lift one lead).All units with AA will benefit from adding 100~125uf in parallel with the K-33E woofer and 230uH in series and 4uF in parallel with the K-55V midrange. I can email you a photo of where to snip if you contact me. Actually I should post a schematic I drew of the x-over as well. I shall endeavor to scan that. JWG

In the first place sir, if you think that was an attack you are mistaken. In the second I am not the one pontificating about "My Mod is great EVERYTHING else is junk." Just because you say something is so doesn't make it true. Your anecdotal evidence about critical Klipsch management proves virtually nothing, except that you claim these people exist and they've said XY and Z. Please provide names and details. Please provide any research results. Their decision to use tractrix addresses many engineering goals. None of which means the exponential horns were junk nor poorly designed. They are different to be sure. Better is a judgement call. Unless you hold exclusive rights to judgement as well. By playing nice in the sandbox I mean support your contentions, not with JBL literature or stomping your feet and name calling but with fact. Your replies are quite predictable and frankly beginning to bore the dogshit out of me. What it's beginning to sound like is that you've dumped beacou dollars into your system and now you need to justify it.And everytime someone points even the mildest criticism your way you get hissy. By the way, any and every time you introduce digital delay into a signal you've opened pandora's box in terms of imaging depth. The signal also tends to sound a bit sterile. Did the pro sound gods mention that? That's why Richard Vandersteen spent so long coming up with a way to do it passively. That's why I'd prefer to live with the Khorns as they are now rather than add digital delay to make them "measure" better. As to point 2 in your reply, the part about you not being a scientist nor an engineer, that sir is quite obvious. JWG

Antelope I must ask what it is you find redeeming about Klipsch at all? If you chop off the top horns and are left with a PWK designed bass cabinet why not pay an Pro Sound engineer to design a push/pull dual woofer system using JBLs pro woofs? This arrangement (at least in theory) results in comperable lower bass distortion. Then you could be done completely with PWK, tailor the tonal balance and--at least to a certain extent--cabinet size to your room/liking. I guess then you'd really show us, by golly! I happy that you now have nothing about which to complain.(Though judging from your posts I don't believe that for a minute) So then I'm led to belive you are bragging up your UBERDESIGN to lowly "bad-listeners" or are merely wild-eyed zealous. Please provide specifics, including component values, etc, about your mods. Send photos if you have them. If you wish to discuss science fine. If you wish to rehash JBL marketing and your complete and utter acceptance of it this is really not the forum.(IT'S PWK's BOARD MAN!) Also, leave the condescension at home. It really is quite pretentious of you to cast aspersions on the listening/engineering skills of members of this board. Especially considering the admitted limitations of your own. Until you are ready to play nice in Paul's sandbox...FINIS! JWG Bad Listener PWK Lackey General Know Nothing

Let's see, First we buy a speak for $6000 a pair and then an additional $3000 in a mod. Obviously the economics of this equation prohibit Klipsch from using this horn on the Khorn. Maybe the Jubilee (If it's really not vaporware) has a similar plan. I must say however, that modern Khorns seem to be pretty smooth, particularly in the low and mid midrange. Having never heard a JBL prohorn take the place of Klipsch drivers I can't comment on the difference. It would be nice to hear them sometime. Having said that there are things one can do without breaking the bank and utilizing existing resources. Many feel the midhorn is a bit "hot" in terms of absolute tonal balance particularly in bi-wire mode. Fine, 3.3 ohms in series and 39 ohms in paralell and you've padded it a couple of db. I even have a friend who's made a jig to cut off the driver end of the horn and then rethread it for a JBL driver. This mod also opens up the throat. Many people swear by this mod and it doesn't cost an arm and a leg. I am not troubled by the Khorns run with a single cable from a Wright SOund Company 2A3 amp. BUt I appreciate your mods. To me, it represents one end of the spectrum with packing the back of the horns with rope caulk representing the other. BTW PWK says in a recent interview that the bass horn was a relatively easy thing to nail down after the first prototype suggesting that the majority of R&D went to the mids and highs. Personally, I feel they've done a pretty good job given budget contstraints. No doubt given a larger retail price they could make significant advances! JWG

Phil, Your Khorns are new eh? Please remove that derned elliptical filter that stores energy and causes your tweeter to ring like crazy. This will take far more edge off your Khorns. Just one snip with a pair of di-cutters and you can remove it from the tweet path. There is a red wire running to the cap nearest the front of the high horn section. Snip this wire to remove the cap and coil from the circuit. It was designed to protect a delicate tweeter driver that is no longer used. The problem is they left the filter in place. No problem for the modern tweet to handle publishsed power levels. This mod takes nearly all the sibilance out of vocals! The best free mod ever. If you would like a photo of where to cut please email me. jwg
