Whatever it takes for your room. A good sub would bring the tweet up to ear level.

Great minds! Field expedient solution that works.

Yes sir. Analog, hand-woven audiophile socks.

Wuzzzer is correct. I tried them in the stands but preferred them on the floor with a 2x4 scrap under the front of each speaker for the up angle. I will get a more glamorous solution. And yes those are extra acoustically absorbent socks. Rug will be back here this weekend and closing the curtains does actually help with early reflections.

I bought a pair of 1978 Klipsch Heresy speakers (E network) about 10 years ago and replaced the squawker gasket and swapped in new motor run caps of the same value as the originals. I did no other mods. Mine have the alnico K55s and K77s. I used them in my basement system primarily for movies and they did fine in that role. About three weeks ago I moved out my Cornscalas and put the Heresy 1s in the corners of my living room. They always manage to make me smile and they always start the time transport as I spin old vinyl I’ve acquired. I’m taken back to memories of hearing a lot of the songs for the first time on a hifi 50 some years ago. Any faults these Herseys may have, I can forgive. The Cornscalas are less colored, have a much larger soundstage etc, and would probably work much better for audiophiles. Jammed into the corners, the Heresys have enough bass. They image well and the phase response is right, for stuff I can easily hear like snare snaps. I’ve owned 2 pair of K horns, Belles, LaScalas, Cornwalls and Cornscalas. In my last house, I had a huge basement area with acoustically absorptive ceiling panels and the K horns were perfect for that room. In this house, not so much. My Luxman 550AXII has plenty of gas to handle the dynamics with the Heresys and for as simple and unassuming as they are, they are a home run. I probably still prefer the Cornscalas in absolute terms but I could live just fine with these little guys.

I will have been on this forum for 25 years in October. Not a frequent poster but I still enjoy my Klipsch and Klipsch inspired home brews. My hearing is not the greatest, but I still enjoy listening to music. Cheers to all the old boys here.

I started another project that I'll never finish. These have been used for living room listening but are as new. I have a pair of 3015LF_4s for sale for $320 for the pair I also have a pair of HF1440 1.4" Compression drivers for sale for $400 for the pair I'd ship everything for $25 to lower 48.

Sorry man, I do not know. I paid a cabinet maker to make these.

I think I am going to build a smaller box, built around a 12” that can go up to 1.5khz without a crazy resonance peak and the ESS AMT1 driver.

Thanks. Yes, I have gotten a lot of enjoyment from them. Thanks for pointing out my 2.25” comment. The front of the motorboard is 1.5”, where the t-nuts mount for the woofer is 2.25”. I’ve edited that part.

In 2019 I had a local cabinet maker build me some Cornwall/Altec 19 inspired two ways from 3/4” baltic birch. He even used baltic birch for bracing and at my request, we ended up making the motorboard 1.5” thick (2.25” where the t-nuts for the woofer mount) for no good reason. These speakers have provided countless hours of crossover and driver experimentation. I have left them configured with 15PR400-4s and HF-146 on ZXPC horns. They are crossed at 700HZ and sound very balanced. I’m sure a digital active crossover would have been much easier to work out but clearly I like old school stuff. The crossover was by far the most frustrating part of working through this design and I don’t claim it’s perfect. They are very dynamic/efficient and more polite than my Cornwall IIs were but still posses a front and center presentation. Alas I think I am ready to move to a smaller box for continued scientific experiments. These are 23.5x24x43.5” and guessing they are roughly 150 pounds each! You can experiment to your heart’s content or leave them as they are. I am near Cedar Rapids Iowa. $2000

Ha. Oh man. Good old days 😀

I think that would probably be worth a try. I have a luxman 550AXII and it got along well with lascalas stuffed into corners. My buddy has a Schitt 20 watt amp and it drives his 96db/w/m speakers to very high spls and sounds good.

I need to keep up. I still look at Fortes as new fangled. Looks like JBL does use a selector that allows switching in various cap values.

Sure. I was talking about the cap in parallel with the series resistor of the attention circuit.
