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:

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.

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: Amazon.com: GS Power Flexible 10 AWG (American Wire Gauge) 50 Feet Stranded Oxygen Free Copper Red/Black Bonded Zip Cord Cable for Car Audio Stereo Amplifier 12Volt Automotive Harness LED Light Wiring : Electronics

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.

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?

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.

I meant connections from the crossover board to the drivers, like the newest Klipsch speakers.

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.

Wow! Gone already.

So I've given up on the ALK crossovers, but the Crites crossovers are sounding really good. New titanium tweeter diaphragms New midrange diaphragms New passive radiators New 2 inch risers New 10awg pure copper wiring New Crites crossovers I also used Kilmat on the horns, which was a huge improvement. I'm pretty new to Klipsch. My only reference points are the Forte III and Heresy III. My goal was to get these closer to the modern Klipsch sound, and I have succeeded! Google Drive image

Nice! The latest Klipsch models use 2" midrange drivers as well. That alone makes a huge difference. I'm also using those SMAHL tweeters in my Heresy pair. Another huge improvement.

I do understand. The pro series are always skimpy on bass by home audio standards. It makes sense in a live venue for the bass to be lower. A different driver or... a better crossover like the ALK CSW-450, which dips an octave lower for the La Scala or Klipschorn, would get you more bass.

No... I've thought about pulling them out of my Heresy pair to experiment, but I'll leave it alone as Al isn't supporting it. It would probably sound great and then flub out at high volumes.

I'm sure the bass will be satisfactory for me. Maybe not for you, but fine for me. Try these "mods" and let me know how it goes. Mod 1: Place unobtrusive braces in the bass bin. Mod 2: Place the speakers on two foot solid wood tables, and isolate the bottom of the bass bin and of the table's feet as best you can. Mod 3: Get a subwoofer Mod 4: Get an ALK crossover with the one octave lower feature. Mod 5: Listen to the modded La Scalas for as long as you'd like, then buy brand new AL5s.

That's what mods are for.

I'm going to need those braces when I get my La Scalas.
