I’m just looking for clues...
So did the T3A autoformers turn out to be one of the reasons the AL crossover did not appeal to many?

The AL-4 and AK-4 schematics are in the Crossover Schematic thread, which is pinned. Why not just build those?
That is not a bad idea. But was there not also the consensus that the AL-4 was less than desirable? I’ll have to look back in the archives...
Funny thing is I remember seeing all the threads on La Scalas and Klipschorns and glazing over because I never thought I would make it that far up the Klipsch ladder. But the seed was planted. And it has been a good crop!
In my case though, I am already in possession of a pair of AA crossovers and if swapping a couple of capacitors is all it takes to see what they sound like it is a no brainer. I would probably still need to do something about the tweeter level relative to the midrange, the resistor or autoformer mod.

I cannot speak for anyone else, but the thought of using the stock K-77 in anything this century is as far from the plan as it gets.
Even the original CT-125 drop-in tweeter option sounded nicer to me. And now with the CT-120 and the SMAHL as options it only gets better.
I was thoroughly impressed with the Crites A/4500 crossovers and always wondered what capacitor changes would be needed to be made to the AA crossover, for starters.
I am surprised nobody else has tried this yet, or was it that bad, lol?

Was just reading another post and noticed @Dave MacKay asking a question that has crossed (no pun intended) my mind more than a few times now.
EVERYTHING Klipsch now designs crosses lower to the tweeter.
The latest La Scalas have crossed at 4500hz for two generations now.
Since the AA seems to hold it’s own amongst the competition how would it be modified to cross at 4500hz?
Has anyone tried this?
And if so how were the results?

What would be involved if one wanted to modify an AA to drop the crossover point to 4500 Hz?
I would be very interested in this as well.
Maybe this deserves it’s own topic!

@Deang, I can't speak for anyone else on here but I ALWAYS appreciate your willingness to share what you have learned and your perspective as a result of what you have learned.
If I remember correctly, you were the first forum member to assist me in my very first post years ago.
And speaking from personal experience, a cottage industry is more a labour of love than a for profit industry at the end of the 12 hour day. No overtime pay and 24/7 accountability.
No thanks! LOL

I tend to get things in the wrong order. I knew at some point La Scalas would enter my life so I bought A/4500 crossovers and CT-120 tweeters when I had the opportunity, before I even owned a pair of the speakers to put them in.
First pair of LS to cross my doorstep had the AL-3 in them and they sounded so good to me I never even tried the A/4500s and CT-120s in them for the two years I owned them.
Second pair had AL crossovers and I was surprised to find that I had no objections to the sound. At all. After everything I had read I still couldn’t take issue with them, lol.
But I did try out the A/4500s and CT-120s in them, just to know what I may be missing. They are two different sounds. And I was impressed with the A/4500 combo. Still wonder if putting a couple 100uf capacitors across the woofer section would make it even better...
The CT-120 tweeters made a huge impact with either/any crossover. Almost non-negotiable. I now have Dave A’s SMAHL lenses and DE-120 tweeters in a pair of LSI Splits with a Crites AB-2 crossover (AL-3 minus the tweeter protection). I know I could just as easily enjoy the A/4500s for different reasons.
Tried AA crossovers too, always sounded like the highs were “missing” compared to the others. Tried them in two different pairs and each time immediately ran up to the speakers and put my ear to the tweeters to see if they were working. Thought I had fouled something up, but no, they just didn’t sparkle like I was used to. Maybe at 90+ db, but that is not happy territory in a living room with La Scalas.
I think the AL knocks the midrange down 6db, the AL-3 down 4db, so there would be perceptual differences there.
If the AL sounds good to you, that is all that matters.

...less distortion begs louder listening levels?

@Racer X, too funny, and I get it!
I bought my son a pair of the Costco Ion Total PA speakers to play around with and was deathly afraid they would steal some thunder from the Klipsch stable.
Was relieved to discover they are two different animals that can co-exist together.
Impressive nonetheless for $200 a pop.

Hey Dave, you could try it on the bottom of the speaker or the back of a riser...
Tung oil is funny, it sometimes dries shinier than I was hoping for.
-
these are actual Klipsch parts from an AL crossover, looks like treated wooden wedges to me
-
They are unicorns. Even the singles are missing links.
I contacted the seller and went out to empty the work van to make room and was immediately overcome with a sinking feeling.
Sure enough when I measured my basement entrance it came up short. And just when I thought I’d found the perfect home for my spare K-33s.
I don’t think you could buy the lumber to DIY these for that price.
There ought to be a bylaw against building single family dwellings that won’t accommodate MWM doubles.

There are many of us here that have tried the Ti diaphragms.
Common consensus:
Tweeter - YES!
Midrange - NO!
They have more output than the equivalent phenolics. In a tweeter that is a good thing, with an unmodified crossover it’s not so good in the midrange. I bought a pair of the mid Ti diaphragms from another forum member and tried them in both Cornwalls and Chorus 2s. Under about 75db SPL they were revealing, above that they were out of balance, and that was with the bandpass filter that cuts off the response above 6khz.
I agree with the above suggestion to keep the woofers stock. Keep your eyes open for one.
Unless you never read another post on this forum you will be climbing the Klipsch ladder and stock speakers sell for more without the diminishing returns of “upgrades”.
The Ti tweeter diaphragms will be useful in whatever you can put them into.

@Rotobadger, sometimes fate smiles upon you.
Those LS IIs for sale by the forum member down the highway from you are a no-brainer if you want a one-and-done, sit back and rest on your laurels, spend two weeks in Mexico trying to have the perma-smile on your face removed by a cash only doctor purchase.
But, if like most the rest of here, you want to always be searching for what if, and what next, you COULD go another route, lol.
I have two pairs of La Scala Industrial splits with upgrades and would trade them both for a pair of La Scala IIs sight unseen in a heartbeat.
Best of luck to you on a giant leap forward.

@Rodakwelcome to the forum.
Something a lot of us overlooked early on are the Klipsch Professional speakers. They are often a silly bargain compared to the well known Heritage lineup. And they take no prisoners.
Another real sleeper to keep your eyes open for are the Tangent 400/500 and better yet the Tangent 4000/5000 speakers. These are essentially taller Heresy 2s that go lower.
As mentioned, stay glued to this channel for alerts (other markets) and garage sale (this forum) posts. And be ready to jump on it.
Ask away and you will get the shared experiences of others here to steer you closer to where you will wind up sooner.
Another sentiment on here is we only regret the ones we didn’t buy.
Oh, and watch that capacitor “pop” when you turn on your 2230, I blew a tweeter in my Cornwalls once...

@RandyH, have you been going through my mail? Lol.
I just recently received my Canadian citizenship in the mail!
Until then I was a landed immigrant. Moments away from deportation, NOT, the Canadian economy would collapse without my tax contribution, lmao.
Fitting story on Remembrance Day here.
My father was in the USAF and my mother in the RCAF when they met at a dance in France, for real. Fell in love, got married and moved back to the States.
I was born on a USAFB to a Canadian mother while my dad was an air traffic controller in Viet Nam.
A few years after his second tour was over we all moved up here to be closer to my mom’s family.
My father was the proudest American I have ever met.

I always wondered about stripping and polishing a pair of K-400s for these LSI Splits.
...never used any of the polishing wheels for the Dremel yet.

I told Dave today that I liked the black on this 301 but the aluminum finish appears as if it were made for my LSI with aluminum trim.

First off, thanks for all of the replies!
Where would I get a polyswitch? From Klipsch?
Klipsch driver specs?
in Technical/Restorations
Posted
@AuralTone, if and when you come across the specific drivers throw them out on here.
There are a lot of members that have resources long gone from any internet searches I can find. And many times the images in this forum have disappeared, I blame the elites, anyone else gets you a slap on the wrist, lol.
The tricky part is getting those members to be actually reading the forum when you post.
But sometimes another member reading the post remembers which member has the goods and gives them a heads up.
Best of luck, and remember, you can’t be the only one who wants to know and the rest of us thank you.
