I didn't know that people considered the 15C an "upgrade"... I always just thought of it as a close enough off the shelf replacement for K33?
Upgrade seems like a strong word?
I definitely would not waste money replacing perfectly good K33's with these?
-
The pics aren't a branded K60M but an EV model... it was close enough... that circular bit under the screw will come out. It isolates the ring terminal from the snout/face plate and is not needed with your replacement because it is built in to the replacement
Hope this helps

I can't find a pic of it but there is a small removable spacer where those ring terminals bolt through the snout/face plate... its needed for the Klipsch diaphragms but you have to remove it to use the standard EV/aftermarket

So one thing I find amusing about this mod kit is that it appears to change the LF/MF crossover point from the factory 650Hz to roughly 900Hz in an effort to supposedly smooth out that region of the network...
And how everyone on this forum went absolutely ape sh!# when Klipsch did basically the same thing on the CWIII

Yeah, wouldn't mind super charging my Heresy 2s.
Maybe they don't any more but Klipsch used to sell an HII to HIII upgrade kit?

This was in the CW IV thread... is it bad info?
Klf30 horn is k703 *Correct (also KLF20 & CF2)
Forte iii horn is k703m *Correct
Cornwall iv horn is k702 *Incorrect **horn as stated by Roy is K603M and the driver is K702
Kpt8060h horn is k702 *Correct
Wasnt able to track the cf3/4 horn model down in the time I looked. *K603 horn was used in CF3 & CF4 models under the assembly # K63KN
Technically the 8060 is a K702M...

Looking at the spec sheets has me lost: What's this?
The Cornwall IV sticker says K-702 but in this case is it the horn or the driver? The sticker is on the driver... the spec sheet says K-702 1.75” (4.45cm) Polyimide diaphragm compression driver. but doesn't list the horn.

The Cornwall IV sticker says K-702 but in this case is it the horn or the driver? The sticker is on the driver... the spec sheet says K-702 1.75” (4.45cm) Polyimide diaphragm compression driver. but doesn't list the horn.
*Klipsch isn't always consistent with information/messaging... that just is what it is... you are correct that the copy does not list a horn but Roy Delgado has confirmed in this forum that the horn used in the CW4 is the K603M
The only other reference i found for K-702 appears on a KPT-8060H, it says it uses One K-103-TI diaphragm compression driver on a K-702-M horn.
*Yes, that is a mumped version of the K-702 horn I posted earlier. Unlike the 703 it has a flange mount for a tweeter phase plug/diaphragm/magnet. In this case it is the same phase plug/diaphragm/magnet used in the HIII & CWIII
The Forte III specs say a K-70 1.75" titanium-diaphragm midrange compression driver on a new Tractrix K-703-M horn.
*I'm pretty sure that is just a typo... it's widely known that the FIII midrange driver is a "K-70-G". You can find pictures on the forum...
The KPT-1260H spec is a one K-703-G 1.75” titanium compression driver on a K-703-M horn.
*It actually says "One K-70-G 1.75” (44.45mm) titanium compression driver on a K-703-M horn" and this is identical to the aforementioned FIII midrange
Most other larger KPT use a K-691 3" diaphragm compression driver. The large-format compression driver is mated to a 90° x 60° K-510 horn
*KPT-310HF = K603 horn w/ K70G driver
Hopefully this helps...

is the k52 & k52h in fact are one and the same driver less the horn mounting method?
Yes. Though technically Klipsch does use the H any more... they would just say K52 w/snout and K52 w/o snout... or whatever. The "H" is just a remnant in nomenclature from it's origins. The K-52-H with the metal snout was the 1st iteration of this driver to make it to production. The very first models also had a separate metal phase plug and diaphragm. It was used on the K700 & K600 horns in the Heresy (w/ E2 network) and Cornwall (w/ B3 network). This was short lived however and disappeared with the advent of the K-53-K (K701 W/ K52) and K-57-K (K601 w/ K52) also used in the Heresy (w/ E2 network) and Cornwall (w/ B3 network) just before the HII and CWII came out.

The K52 (phase plug/diaphragm/magnet) was used in the K-53, K-57, K-58, K-59, K-61, and K-62 assemblies.
Side note: all of the assemblies above will use either a 701, 601 or 602 horn. The driver mounting flange on these horns is made/designed specifically for the K52. There have been attempt to throw adapters on this flange to mount std 1" drivers, this is ill-advised. Also, the snout on the K52H has changed over the years. The original metal snouts had an aperture of around 5/8" which matched the original K700 & K600 horns it was used on. Over the years this aperture was enlarged to mate to newer Tractrix horns
-
When someone says K52 they are referring to what you see on the left... the K52H (right) is generally assumed to include the threaded snout because that is how the driver was first acquired, though technically the H just stands for Heppner (the same way the E in K33E just stand for Eminence).

I know the molds for the 703 & 603 have been changed a few times over the years... even before the addition of the mumps. On the 703 this was mostly bracing to support the driver but when they stared using the 603 in the KPT line they added a large mounting flange so that it could be mounted to the same articulating bracket the 510 uses.

Klipsch isn’t always all that consistent with its numbering/information...
The original K702 horn was, to the best of my recollection, a 703 with a tweeter mounting flange rather than the threaded driver mount
-
So technically the “K-702” in the H4 and CW4 is referring to the driver...
From the H4 spec/copy “K-702 midrange is mated to the K-704 Tractrix® horn for a wide coverage pattern“ -

By endorse, do you mean that he no longer considers its use in new or upgraded designs?
To my knowledge he has never considered it for use within a Klipsch design? Upgrade or otherwise? -

The Chorus II mid driver is actually a k-61-k. The focus of my comments was supposed to be on the merits of doing these experiments as opposed the merits of specific drivers, but I did a bad job of it.
The K61 designation is for a horn/motor assembly... it utilized the K52 motor (diaphragm/magnet)
