Yes! What a difference three years does make. Looking back at this thread after finally building a pair of ALK clones, or five to be exact… That 33uF cap in the CSW 450s is/was not doing your La Scalas any favours, anyone’s for that matter. That is the value for a 600 Hz (roughly) cross, a 47uF cap will make the La Scalas come alive. No wonder you preferred the Volti VTK 400s, amongst other reasons. I would bet the Volti has two 24s paralleled for 48uF.

@Delicious2, if all else fails P-Audio makes a copy of that tweeter. I THINK you can get a pair of them off eBay for $50. Whatever the sonic differences are will match.

Hi @jjptkd, yes the 396s use the same foam, and probably the same spacers on each screw holding on the grille. Hope you had your speakers laying down when you pulled the grille off, lol. Just this week I finally got around to cobbling a make-shift pair of stands. I think I paid about $50 CDN for the hardware at Home Depot, what a time to be alive, lol. CAVEAT ! They are little front heavy, if bumped from behind or pulled from the front past about 10 degrees they are going to tip forward. I just wanted something to get the bottoms off the floor to keep them from getting scratched and at the same time raise the horns to ear level, I’m 6’5” and the 6” of lift on these speakers is perfect.

I think you are thinking of the Tangent 400. It was a Heresy 2 in taller ported box. There was a Tangent 500 too, using a passive radiator instead of ports. The later series Tangent 4000/5000 are the real sleepers. They had 4 ohm woofers and noticeably better bass as a result.

@Mom, Turntables are a very personal item, not like getting him a tie, lol. You’ll need to get a mole in the organization and ferret out what his heart desires. …someone with an appreciation for all things audio, get them chatting him up and have your agent straight up ask him what he fancies

Going price on a pair of klipsch LaScala
geoff. replied to RBurnJames's topic in 2-Channel Home Audio
Recent developments and advancements in the understanding of all things Klipsch have led to the conclusion that the K-77-M should not be used with an AA crossover. It is too hot. WAY too hot. The K-77-M is pictured in this pair of La Scalas. The AA crossover was also designed to be used with the single phase K-55-V. In the speakers pictured here the date code is “W” which would imply the dual phase plug (soldered lug) K-55-V is used. The dual phase plug driver extends higher than the single phase plug driver and is not optimal for the AA crossover as designed. Whether these came stock from Klipsch like this, or they were modified, I don’t know. I do know there were anomalies during driver and crossover changeover years. But as these stand right now, they are not representative of what the Klipsch sound should be, according to recent discussions on here, with all the graphs to prove it. Don’t despair, others in better condition for the same price will be along soon enough. And when they do show up don’t hesitate to ask away on here. Welcome to the forum, -
@Jeff Matthews, A Bluesound Node will give you free access to Spotify. There will be commercials periodically, but nothing like You-Tube. The only trade-off is you won't find Neil Young on Spotify, LOL! You will also find every radio station you've ever heard on the Node. But that will get old fast once you start chasing every album you never owned on Spotify. I rarely ever listen to anything else now. I never understood why people were selling off entire CD libraries, until now.

@nickyboy6100, maybe a silly question, but have you enquired at Klipsch parts?
-
what did you come up with for stands?

Wow !

LaScala Questions about Crossovers and Drivers
geoff. replied to Trinity3's topic in Technical/Restorations
@Deang, a little late to the party, work is really starting to get in the way of this forum, but I snapped a picture of the terminal cup/plate. Ya, who knows what someone else did to those La Scalas before I got them? They had an $8 Rat Shack piezo tweeter in one tophat and one K-43 ohmed out at 20 ohms. For eight years now I have been trying to figure out what is wrong with my perception because a pair of pristine AA crossovers, even after recapping with pseudo-authorized (mylar) capacitors, has never sounded like “all that and a bag of chips” in any of the FIVE pairs of La Scalas I’ve owned over the years. Each pair had K-55-Ms… I never found the midrange to be too loud, I always found the treble not as bright as I would have liked, but that is not uncommon for me. Before recapping I had to put my ear up to the K-77s to ensure they were working. Now though, even with colorful puppets to explain what I was hearing, thanks @mboxler, I’m left with questions. Hypothetically, not suggesting anyone modify any Klipsch product, how would a person correct for the overlap using an AA crossover with a dual phase plug driver? I seem to remember a suggestion to add a .35 mH coil to the positive squawker output, a la A/4500. Would another possibility be to add the same elliptical filter used in the AL series of crossovers and change the .245 mH to .125 mH? I really want to hear what the fuss is all about with the AA crossover. For starters, I imagine the un-smudged crossover would result in better imaging. So is what I’ve been hearing more like an “A” with better tweeter protection? Another question now springs to mind… how did the widely accepted crossover points become 400 and 6000 Hz if the graph clearly shows 4500? …my whole life has been a lie, lol -

LaScala Questions about Crossovers and Drivers
geoff. replied to Trinity3's topic in Technical/Restorations
I own a pair of mis-matched LSI Splits, one came with the K-55-M / AL crossover and the other came stock with the soldered lug dual phase K-55-V / AA crossover. There has been discussion over the years, and still is on an “authorized vendor” site, that you cannot use the K-55-M with the AA crossover as it was not designed for it. The reasons originally proffered were the K-55-V rolls off sooner and has a dB less output at certain points in the frequency response curve. Well, the Klipsch FACTORY INSTALLED K-55-V dual phase driver in the La Scala Industrials using the AA crossover runs just as high as the K-55-M, and it turns out the frequency response results were based on test samples of the K-55-M that do not reflect final production units. It appears “the data on the Mig is inaccurate”. -
…an object in possession seldom retains the lustre of an object in pursuit @Jvitti1970, did you wind up selling the ALK crossovers you had listed a while back or did you keep them?
-
I would buy all of those on principle alone
-
After taxes and shipping, from multiple sources, I don’t know if you could order the parts to build them for less than $500.
-
…I think you’re safe to start the bidding at $350

So…, my La Scala-ish speakers have unmentionable, unauthorized parts in them. Someone broke into my house and threatened my family if I didn’t let them perform these mods… From where I sit, quite figuratively, it’s not an issue of a bass trade off, the bass of the 396s although spec’d higher sounds lower to me. And the K-48 (any iteration) produces tight, fast, clean, and detailed bass. It’s more of a “live sound” versus “studio sound” argument that is brewing. I have yet to use more than simple tone controls on the 396s, comparing both sets of speakers “flat”, but wholly believe equalization may take them out of the studio and onto the stage. Not there is ANYTHING wrong with their sound as they stand. These remind me of my first pair of Tractrix horn equipped speakers, Forte 2s, only with more of everything. I find myself looking up from my screen and replaying songs I’ve listened to for decades. Again. ANOTHER thing I have yet to try is removing the grilles. These are pro models, built for battle, and there is an acoustic foam liner behind the perforated metal grilles. Removal of the grilles would no doubt bring a presence to the sound that cannot be achieved behind these screens. ONE CAVEAT to anyone new to these, @Heritage_Head, and others thinking of removing the grilles… Lay the speakers flat on their backs before removal. The screws, all 11 of them, have a hollow tube spacer between the motorboard and the grille. And take your time, I can’t even count how many screws I’ve stripped and surfaces I’ve scratched in my excitement, sigh.

…I envision myself with a four foot 3/8” threaded rod, a grinder and some bluing
-
They’re BETTER than the old Heritage! There is a bevelled plate under each screw, so you could just twist the wire and insert it under the plate and screw it down. No clockwise loop, lol. I would have soldered the ends if I didn’t already have (a box of) spaded terminations lying around.
-
My son commented again today about the soundstage, lol I have them angled such that the trapezoidal sides are parallel with the walls. It suits my OCD fine and FILLS the room.

The bottoms look like the tops! (Another one of) the REALLY great things about this second version, the SMA-II, is the simple yet effective barrier strip terminal connections instead of Neutrik.
