geoff.

@Wilson Hines, I replaced the factory(polyester) capacitors with Erse polyester/mylar capacitors in an ‘84 pair of Cornwalls and a ‘90s pair of Chorus 2s within the last few years. It was moot at best. I could discern no difference one way or the other. My takeaway was that polyester capacitors not subjected to brutal extremes have generational longevity. I have also played around with polypropylene capacitors in other Klipsch speakers that came stock with polyester caps. They always sound brighter. More resolution and clarity at low volumes, “harsher” as you crank them above 90db, from the listening position. One thing I always found to be an improvement from where my ears sit is the titanium tweeter diaphragms. They simply weren’t available originally and were used in later models. Biggest bang for the buck and reversible. CAVEAT: if you go that route take your time, they are delicate, ask me how I know… Fortes are a great speaker, but if and when you decide to take the next step, a stock speaker holds it’s resale value better. Cheers,

…just buy it with PayPal and say you never got it

…I’m hip, I’m hip

Cool!

That is a good idea. Thanks, as always, for your help Dean.

…they won’t hold a candle to your LSI-BGs, LOL!

…just a caveat, if and when you get your new horn, take extreme care when tightening it These old(er) plastic horns really crack easy (ask me how I know). My new friend is Krazy Glue.

Hello, not sure how this one has flown under the radar so long, But if your heart is set on Cornwalls, the III is the way to go. Far superior tweeter, and crossover.

@Schroedinger, if you think you can sell the Cornwalls for what you paid, should you not care for them, it’s just your time that you’re out. And you will always wonder “what if” if you don’t try them.

@mboxler, what tweeters are you used to listening to in your La Scalas(?)? Within the past couple of months I built a pair of polyester capped AAs as a reference to compare other crossover builds to. I am trying to assemble a second set of La Scalas to loan out to friends and family so they can see what the fuss is all about. Trying to keep it as close to original as possible, but after listening to aftermarket tweeters for years now I couldn’t get the K-77Ms to sound right either.

You guys aren’t going to believe this… I have a pair of Realistic Nova 9s in my basement that I was just about to donate to a co-worker for a vintage system. I am in the process of sending him the archive photo from the ‘73 (!) catalogue and lo and behold. …someone stuck a Klipsch logo on it for clout, lol

I'm still very interested in your thoughts on the sound of the AA vs. AL equipped La Scalas.

It looks like the AK and AL-3 are essentially the same crossover. The AK omits the tweeter protection and has a negligible few extra uF in the woofer shunt.

hast du etwas zeit fur mich…

…if Dr. Seuss autographed the plans it may be worth it

…I’m not sure, but it is a one sentence long word with no spaces, and leaves no room for ambiguity

These lasted a day up here, can’t say what they actually sold for, but I think the price was fair for what you were getting.

The AL-2 looks to be, for all intents and purposes, an AL-3 with the exception of depleting the stock of the formerly ubiquitous, but now out of favour, 2133s (2.5mH) coils by using them in series to form the 5mH squawker bandpass.

…I’m dying

…I’m never shoveling my driveway again, I miss too many sweet deals

On the upgrade to AL-3 path, the AL uses a different autoformer than the AL-3, so it’s gonna be tricky/more costly to get the approved parts. I would be leaning towards something that may bring out the highs better, a mythological thing hither-to-unknown to the people of this area…
