I got the titanium diaphragms for my Chorus II speakers, as well as the Crites Chorus II crossovers. The sound is much better. However, it does not approach the upgrade of the ALK crossovers. As it turns out, ALK is not developing crossovers for the Chorus II. Is it possible to get the same ALK quality elsewhere?

These were listed at $200 a few weeks ago. I guess they wised up.
-
The price is now $1,200.

I've edited the title and description to better reflect upgrades and updates. I've also applied another round of Old English Wood Conditioner and Cleaner, lemon scented. They look even better today.

These speakers are ready to rock. They sound so much better than new. Perfect stage for more mods, or just to love them as they are.
I replaced the tweeter and mid diaphragms, replaced the crossovers, and a few more mods. You can have the old parts if you want them. I'm only selling these to make room for La Scalas. Here's the whole list of updates/upgrades:
- New Titanium tweeter diaphragms
- New Midrange diaphragms
- New Crites Chorus II crossovers
- New 10AWG pure copper audio wiring
- New 2 inch risers
- New passive radiators
- New Kilmat insulation for the mid and tweeter horns

Wow! Great looking speakers at a bargain price. These shouldn’t last long.
Thanks. They lasted a whole 24 hours.

Just a quick update to the Chorus III project. Just got a pair of large MAHL tweeters. This is basically becoming a Super Chorus II speaker at this point. No thoughts on the drivers yet since I just got them installed and it is recommended to let them break in. I will be eventually doing an A+B comparison with the stock tweeters (with Crites titanium tweeter diaphragms).

I had to take the risers off my Chorus II pair. They were tattered and splintered by the previous owner. I installed the new 2 inch high style black risers for simplicity. To my surprise, the bass tightened up, and gave me a bit more punch and definition. The technical term for this sonic phenomenon is 'more better'.

Very nice. Those and your chorus. Someone needs that 10 AWG copper wire in their life. GLWS!
Very true. I actually wired the Chorus II pair with half copper/half tin wiring. Definitely better than stock wiring, but not as exciting as anticipated.
Then I wired them with pure copper cables, and they came to life, just as expected.
I might use an ohm meter the next time I wire speakers, but playing it by ear is working fine for me so far.

Perfect starter for Super Heresy projects, or to love them just as they are. ALK Crossovers, 10AWG copper wiring, SMAHL V2 tweeters, and more.
The risers in the photo are included.

Heresy I pair, 1980 I think. I bought them in the Spring of this year to experiment with mods. They now sound more like Heresy IVs minus the rear port. Pictures and details here:

I get "this listing isn't available anymore...." page. You get it because it's in your browsers cache. Either that or the link is faulty.
Ah... yes... the cache thing. Sorry you missed it.

My brief foray into the vintage Klipsch mod world leads me to conclude that the Klipsch factory/lab/studio is the ultimate mod shop. Common sense has a firm grip on me. I can't shake it. So my next acquisition will be brand new La Scala AL5s, or maybe the La Scala 70th Anniversary.

OK I will bite. How do you measure and control the resistance from the aggregate of all the components from the amp output terminals to the front of the speaker? Everything from the connection terminals to input and barrier strips and capacitors and did you measure each inductor for uniformity and trim each wire in each equivalent function to precisely the very same length? Did you measure the ohms on every driver to make sure they match and research which ohms output sounds the best? Not all drivers are created equal you know. Have you soldered in all internal speaker wiring to make sure no faulty connections are running up resistance?
Capacitors have resistance too. Did you go through your crossovers and take a combination of two capacitors soldered in parallel for every location used to get correct UF value where they are used thereby reducing the ESR?
My approach is a bit less scientific. I cut the length of the 10AWG to match the skinny wires that came from the factory. For my Heresy pair, I got it right the first time. All drivers were balanced. For my Chorus II pair, I had to double check and reconnect the wiring until everything balanced out. They sound great now.
I'm new to Klipsch. I only have experience rewiring, re tubing and soldering connections in very loud tube guitar amplifiers. When the band says "Turn it down!" I know my sound is right. Besides, I use microphones now, so I can carry a smaller tube amp to rehearsal and gigs. I really like the Klipsch sound, because those horns really put me in a virtual audio/live setting.
This is the wiring that I used:

Apparently it's itty bitty science and logic.
Done a blind test between your 10awg against 12/16/18? Doubt it, but if you think you can hear it, then that's all that matters.
I did try 12 and 16, not 18, unless that's the stock wiring from the factory. 10 AWG was consistently better. Now it's up to you. Prove your theory to yourself. It's just wires.

Two feet of 16 ga copper wire has a resistance of 0.008 Ohms.
Two feet of 10 ga copper wire has a resistance of 0.002 Ohms.
Even two feet of 20 ga copper wire has a resistance of only 0.02 Ohms.
Considering that the voice coil DC resistance is in the Ohms range, all are negligible. In fact you'd be hard-pressed to find two drivers of identical make and model in which the voice coil resistances were within 0.018 Ohms of each other. Not to mention the fact that there are often padding resistors present in the midrange and tweeter circuits.
Apparently I'm hearing itty bitty resistance differences from 10awg wire. I have experimented in the audio realm, not the paper realm. Don't knock it 'til you try it.If you have already tried a 10 or 8 awg pure copper wire experiment, and discern no difference, I can respect that. If you haven't tried it, how can you actually know the difference?

Still not necessary. But hey, they are yours. Have fun.
It is absolutely necessary, and fun, to experiment with 10awg copper wire. Anyone interested in improving with crossovers should try the 10awg connections to all drivers. So far, it has really improved my Heresy I pair, and two weeks ago, my Chorus II pair. At some point, I will have La Scalas, and will try it again. You get a little bump in volume, presence and detail. The electrons are just happier. Experimenting and doing a listening test, like the Klipsch engineers, is the only way to tell the difference.

Not really, but good try. Considering that the internal wiring on the network is 16awg or less, 10 awg is not close to being necessary. JMHO of course.
I meant connections from the crossover board to the drivers, like the newest Klipsch speakers.

Does these work with the H1’s? And yes I have Dave’s b&c120 tweeters
Yes indeed. I have these in my Heresy I pair with Dave's tweeter. Add 10awg pure copper wire for all connections, and you will have sound as good or better than Heresy III or IV.
