Titanium Diaphragm Upgrade?

[FredC]

Has anyone done a Titanium Diaphragm upgrade on their K-85-K (or similar) Tweets? I was wondering if it makes that much difference.

I recently picked up a pair of KG 5.2's as part of an equipment swap. I almost forgot how great Klipsch sound since I haven't had a pair in years. I'm still not sure what to do with them tho. :scratch2:

Yes, my 5.2's have the titanium diaphragm. Best bang for the buck upgrade IMO.

Cool I was hoping to hear that. Did you get yours from Bob Crites?

 

[gatorvrx]

Yes I did. My Fortes, 5.2's and KG 4's all have the titanium diaphragms.

Great upgrade. You won't be disappointed.

Awesome.. Bob's got a great site plus he sells the Titaniums for the same price as others sell the polys. Gonna order them now. Thanks everyone!

What to expect - titanium diaphragm upgrade

Yes, my 5.2's have the titanium diaphragm. Best bang for the buck upgrade IMO.

I just nabbed a pair of 5.2's from a local thrift store. On passive radiator needed a little rubber cement on it's surround but it seems to be working fine now. I've got them hooked up to my 2A3 Paramours.

I just started listening to them last night so I'm not used to the sound yet but what sort of change in sound could I expect from the titanium diaphragms?

My experience has been cleaner, smoother highs. It's really hard to explain. I replaced one and then cranked up the 5.2's, the speaker with the titanium diaphragm just sounded fuller if that makes sense. The same happended with my Heresy's when I built one xover at a time and listened. Big difference in sound.

Many on this forum have replaced the stock poly diaphragms with titanium. They will chime in soon.

gatorvrx's experiences mirror my own...I have done the Crites Titanium tweeter diaphragm modification to kg2s, KG 4.5s, KG 5.5s, Quartets and Chorus IIs...well worth the price of admission...

Excellent. Thanks for the comments.

I listened a little more last night and read a few things on the Klipsch forums. Some of the folks over there said that the caps in the crossover ought to be upgraded too. I found the diagram for the xover but there's one part I don't understand. It looks like it might be some sort of protection for the tweeter. It's marked RDE 070. Can someone explain what this is, if it's needed, and if it needs to be replaced also.

I believe that's the polyswitch Klipsch used for tweeter protection in most of the bigger KGs. Bob Crites' x-over repair kit includes caps and polyswitches.
