CANT

Confirmation bias is a b!tch...

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 https://www.audiocircle.com/index.php?topic=166996.100

Maybe they don't any more but Klipsch used to sell an HII to HIII upgrade kit?

Technically the 8060 is a K702M...

Hopefully this helps...

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.

To save time... 704, 703, 603 & 604

This is the 602...

This...

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“

To my knowledge he has never considered it for use within a Klipsch design? Upgrade or otherwise?

The K61 designation is for a horn/motor assembly... it utilized the K52 motor (diaphragm/magnet)
