They're all set up now. Listening to Nora Jones CD. On "Don't Know Why". Nora's voice is much more natural and present with these little upgrades. Guitars on the other tunes are crisper and more detailed. I do understand now what everyone says about the conspicuous absence of bass on stock vintage La Scalas. I've got a fix on the way. These speakers are great.

Outfitted the first squawker with my Kilmat scraps. ALK's advice on damping material is really good advice. This is my third horn damping effort; Heresys, Chorus IIs, and now my La Scalas. My speakers consistently sound better with this treatment. The first speaker is done. I'm not going to change the caps right now. I'd like to see how they sound with new wiring. When my ALK crossovers come in, I will probably use an Audioquest type of wiring.

Pretty dusty, but no leaks or corrosion. I'll clean them up, and see how they sound connected to new 10AWG copper wiring.

Ah... ok. Well, they sound bigger so I want them.

I like alnico, too. I have blue alnico speakers in my Vox AC-30 guitar amplifier. The amp sounds great on Fender Rhodes, too.

Hmmm.... Perhaps that's why Al offers the Super AA-X upgrade for $130.

Yes, and the AL5s have a 2" mid driver. Actually, the 2" mid driver is why I'm getting the AL5s. That's a mod I'm not willing to do for these old La Scalas.

The spades carry the sound of the thicker wire nicely. If I had spades with a better metal, that would probably help, but these spades have worked just fine with my Heresys and Chros IIs. As far as bi-amping goes, I'll do that when I get the AL5s. Right now I just want to hear these old speakers sound new ++.

K-77 tweeter tricked out with 10AWG pure copper audio wire.

Good to know. I'll do an A/B test.

They're actually pretty beat and scratched up. They were stored stacked with one on top. AA Crossovers. I'm impressed by the sound, even though I know an ALK crossover will take them to new and improved sonic capabilities.

Push pins. Very convenient.

It happened, and it was dusty. All cleaned up now and ready for Kilmat. The K77 tweeter sounds pretty nice. I may keep them.

Good timing. I just pulled one out. It's a K400.

Very first update. I replaced the K-55V rubber washers. The old ones (see pic) were pretty dried out. This $8 update really does improve the mids. It's the first time I'm hearing the highs in Frank's voice. The horns in the orchestra are sharper as well.

Here they are. I'm going to see just how close I can get them to the AL5s. I'll get the AL5s later, but tinkering with these will be fun.

Keeping both is definitely the best idea; I just can't do it right now because of limited space. Covid killed my 'bigger house' project, but as soon as I'm back on track, the Big Klipsch Show will resume!

I just did. They're a bit beat, and definitely need new crossovers. Funny thing... right now my Chorus IIs sound better.... but in the pic, you can tell they're jealous.

I just wanted to see if I could get them to be mini La Scalas. I made some really good sonic improvements, but they're not La Scalas.

My Chorus II crossovers. One was not functioning (short wires) so I replaced them both with new Crites crossovers. I'm passing these on to the new owner of my Chorus II experimental pair. It was a very good experiment. Is anybody rebuilding these? I just thought the new owner would like to know.

Sold

ok

This was not the plan, but I picked up a La Scala pair before I sold my Chorus IIs. All original La Scalas vs upgraded Chorus IIs; the Chorus II pair definitely have better highs, punchier bass, and more detailed mids. However, I can already imagine the sonic upgrades for the La Scalas. The Chorus IIs are jealous.

Yes, they are still here. Send me a private message with your cell number if you can.

Thanks. Another little audio factoid; the upright bass and electric bass are more defined and less boomy after installing the new styled solid pine risers. This may be a factory secret. Hmmmm....
