It was a total fail. The output of the Academy verses the output of the horn loaded LaScala was akin to bringing a water pistol to the battle of the bulge.... I've since sold the Academy's.
If you have the room, another LaScala. If you don't have the room, I'd go phantom (which is what I've done over the years)
I also bought an Academy, mostly because it was magnetically shielded. The Heresy I had used for a center was messing up my TV. The Academy didn't work for me, and I sold it to a forum member, who sent me a great looking Klipsch shirt in return. I ended up buying a single Belle, which is beautiful and sounds great between the Khorns. Thankfully, the flat screen TVs don't suffer from magnetic problems the way the older CRTs do.

Something that sounds as close to the left and right La Scalas as possible. A side benefit is that a large speaker like a La Scala or a Belle makes a nice TV stand.

Heresy is a 12 inch woofer -
My Heresy I's woofer is mounted from the rear, behind a 10 5/8" diameter cutout. My Heresy II woofer is mounted from the front. The OP probably didn't unscrew the back of the cabinets to get the woofers off so that he could measure them, which likely accounts for his reporting them as 10".

It looks like an 8 pin SIP. When I was a teenage party animal, I was unsoldering and soldering in new op amps when my Pioneer Supertuner under dash stereo blew them out. Today the young novice hobbyists don't have Radio Shack kits to solder together, or even know who Alfred P. Morgan was. I have a whole collection of his books, purged from libraries around the country. The instructions for the last kit I put together (a 4 tube AM superhet) were printed in Japanese, an enjoyable challenge, but it worked.

I'm sorry for your loss, Gary. The S in the serial number indicates a 1978 manufacture date. I measured my Heresy I just now, and it seems you likely have a Heresy I pair. Welcome to the forum.

X in the serial number indicates a 1982 manufacture date. That date means these are Heresy I, as does the question of taking off the back. You ask about getting them back into shape. That usually means renewing the 38 year old capacitors on the crossovers, which is fairly inexpensive. Other stuff needs to be tested by connecting these to a music source and listening to the individual drivers, one at a time. That determines what's working, and if anything needs to be replaced. After that, enjoy them. I've owned five Heresy I and II since the late 1980s, and still have three.
-
A multimeter will give you a resistance measurement, which will tell you if a voice coil is open or not. But it won't tell you if the driver still sounds good. Your ears will tell you that part.
-
Or just stick a paper towel roll up to your ear and listen to each driver. Disconnecting the drivers one at a time will change the impedance at the amp, but won't hurt anything, particularly a simple tube amp, for a short time until you figure out what's working.

A pair of LaScala LS-FB I bought new in 1988 or 89 had composite horns.
-
The website says the output is microprocessor controlled without any active devices or fuses in the output path. An active device, like a relay, prevents DC voltage from a shorted transistor or other device like an op amp, from reaching the speakers. When you turn on an amp and several seconds later you hear a click, thats a relay or relays turning on after circuitry has determined there is no DC output from the amp. The Schiit rep is correct when he said the amp is outputting too much power to the speakers. IMHO, poor design. The wattage rating of your speakers and of the amp have nothing to do with the problem here.

Never would had thought of that and see the thinking behind it.
Analog meter movements are frequently sold that way, too.

Welcome to the forum. The usual path is to figure out what you have, decide where you want to go, then fill in how you want to get there. Do you have any electronics, like a home theater, or a stereo receiver? Do you play computer games, or listen to music? If so, how? On your phone, thru an online device like an Alexa, or stream it thru a computer? Next, where do you want to go? Music thru the speakers, movies thru the speakers, computer sounds thru the speakers? Last step is how to tie it all together. The speaker company guys would love to sell you some expensive specialized speaker wire, but Paul W Klipsch said that lamp cord is adequate, so save your money.

What is forum policy on copyright material? I have the magazine and can scan it, but I don't want to step on anybody's toes.
It looks like @seti made that post on Audio Asylum. Maybe he'll stop in and add a comment here.

Pissing off the neighbors since 1946. Where have I heard that before?

Locomotives got that crap also, shuts the motor off when engine temp and a few other parameters are satisfied. Most have a 5-10 minute delay and a warning horn, some don't. PITA to be working on something, then it shuts down on ya, especially when the HVAC was running and the sun is beating down on that steel cab. Bigger PITA when its on the list of things to be tested and signed off, and then it won't shut down.

I bought new La Scalas. 2 years later, I bought used Klipschorns. The next year, I sold the La Scalas. I don't miss them. I still have the Klipschorns. When they got lonely, I bought them a Belle.

I spent a fair amount of time on the layout which I'm pleased with. The enjoyment came from reading, sourcing, preparing and assembling these. I drive these LaScala's with a 2A3 amp I built, and the whole setup works well.
Nice work. Anytime you can take wires that go from Point A to Point B and make them look good doing it, that's art.

If the old caps are glued in and soldered in, cut the leads as close to the cap as possible first. Remove the glued in cap. Then turn your attention to the lead. Hold what remains of the lead with a pair of needle nose pliers, and heat the solder where it attaches to the board. You can maneuver the lead that way, without the old cap being in your way. And don't forget to take a couple pictures before you start so that you don't have any questions about where the new caps go.

My advice is to focus on the tweeters and crossover...add the Crites TYPE A/4500 Crossovers and CT120 Tweeters
The A-55G was/is out of stock until next year, the tweeters and crossovers you could do before then.

Gotta wonder how many of you on this forum are actually taking this supposedly wonderful drug, rather than simply slinging the Fox News right wing bullshit rhetoric. Or are you really just taking your normal Flintstones gummies?
My sister in law takes it for lupus. She's an asthmatic 4'9" Asian in her late 50s weighing about 90 lbs. One of the first reports I read about hydroxychloroquine was that it was noted how the ones that were taking it for lupus weren't infected. This is a plus for her, with her weakened lung function, and her husband as well, who has been thru cancer treatments, had a heart attack, and who knows what else. To answer the question, I don't take it now, but would if it were prescribed.

I am trying to sell my father in laws klipsch la scala b25 speakers he bought over 30 yrs ago. I dont want to RIP anyone off, but I was told these speakers can sell in the tens of thousands, but we were only asking 6 or less. I'd like to know the honest price for them, because I dont want to over price them
Klipsch still makes the La Scala, the current retail price is $12,000. But 40 year old cars don't sell for current retail, neither do 40 year old speakers.

Thanks for keeping us up to date on this, Gary. I've had the 2010 posting printed, bookmarked, and saved, awaiting the day I get motivated enough to make backs for my horns. This is a work of art.

Unless Saint Peter listens to Klipsch Heritage speakers, I'm probably going to do time in a very warm place some day for telling my wife the lie that there was no way I could connect her karaoke machine to my 1967 Khorns.
Welcome to the forums, Matt.

Don't touch the woofer with a soldering iron. Instead, disconnect the wiring somewhere between the woofer and the crossover. Then take a resistance reading of the woofer there.
