If you haven't already, unscrew and re tighten all the input/output screws on the crossover. If the drivers have quick disconnects, unplug them and reconnect them several times. This will remove oxidation and give a much better signal transfer.
I will try this. Thank you.

1) check all the wiring connections to the amp -
-2) with a 2nd amplifier/receiver - do a test with the LaScala -
3) prior to swapping with the 2nd amp , make a test with 1 speaker plugged in at the time , first test the left speaker only , then the right speaker , on the same channel and vice versa -
4)- check any switches or routing equipment close to the amplifier
I've checked the connections on the amp. Everything is secure.
Unfortunately I don't have another amp available to test with.
I don't have any network gear located close to the stereo. I do have a TV mounted on the wall above the amp which I unplugged and that didn't help. -

Does volume from the amp cause it to increase? Both speakers? Are all drivers fully secured? Crossovers secured?
The clicking sound seems to stay the same regardless of how much I turn up the volume. Both speakers. I've never touched the crossovers but they appear to be secure. The other thing I notice is that I have to turn up the volume to almost 12 o'clock to really crank these things which really surprises me considering the efficiency of the La Scalas.

The likelihood that the capacitors in your 40 year old crossovers are still within specification is minimal at best. The best possible upgrade is determined as to what your budget would be. Capacitors can range from a couple of dollars each up to a couple of hundred dollars each…
What kind of effect or impact can out of spec caps make on the sound? -
What is the likelihood that all of the parts on my 1979 AA Crossovers are still within specs? If I'm going to replace caps what are the best possible upgrades I can make to these crossovers?

I have an all original pair of 1979 La Scalas that I purchased recently and just started listening to yesterday. I've discovered they are making a slight clicking or ticking sound every few seconds. I removed the source from the chain and have it isolated to either the amp (a brand new Tsakiridis Aeolos Ultra) or the speakers. Does anyone have any ideas what could be causing it? I would connect another pair of speakers to the amp to further isolate it if I had any available.

It doesn't appear to be the same fabric.

----------do you mean grilles with badges over the tweeter and midrange , hey that was quite expensive by the way in those days , it was a dealer only installed option , they stapled the grilles over the HF/MIDS , that kept the dust from reaching the inner part of the horn --
Notice how the fabric was sandwiched in between the drivers and the cabinets? I think I want to remove these and hopefully I can remove the staples without doing any damage to the cabinets.

I feel lucky to have been bestowed these speakers who were owned by such a great musician. They have a few blemishes that I would like to fix. Also, at some point Joel sandwiched some black fabric between the upper drivers and the cabinets and I would like to remove it. Would it be sacrilege to restore them to like new?

Hi there, I need a recommendation for best bang for the buck speaker cables for my 1979 La Scalas. Someone suggested the Canare 4S11 cable from Blue Jean cables. I'm going to be using a tube amp (Tsakridis Aeolos Ultra) to drive them.

Did you buy those from Mary Frances? If so, those would be the late great Joel DiBartolo's speakers.
I will see if the Museum Curator, Jim Hunter, can look to see if those serial numbers are in the written log books and if they are, get you the information on the date those were made and which dealer they were sold/shipped to.
If you don't know who Joel DiBartolo is, here is a good start:

Hi, was Jim Hunter able to come up with more information about these speakers? I would like to know as much as I can about their history. Thank you! -

Hope he is listening by now.
Not yet. I need to pull them back out away from the wall and have a look. I need to figure out what ends to put on my speaker cables. Plus, I just got my streamer yesterday and I'm waiting for my DAC to arrive.-

found a pair of LaScalas, did you? Congrats!
I bare wired mine. One less connection to go bad.
not to mention, the spades I got, for the wire size, wouldn't fit on the crossover
I did find a pair locally. Can you please send me a pic of where the wires attach on the crossover? Thank you!
-
Can someone please tell me how to connect speaker cables to my 1979 La Scalas? Actually, I'm going to order cables and was wondering if I should get spades or just use bare wire?

Those metal button feet, combined with the flat bottoms or the original La Scalas, make them easy to slide around on carpet floors. With the La Scala II, things are not so simple. Not only is each speaker 50 lbs/23 kg. heavier (175 lbs/80 kg for LS2 versus 125 lbs/57 kg. for La Scala), the bottoms of the La Scala IIs are an open box style, with square corners. This means that they don’t slide easily on carpet. Instead, they tend to dig in, even after the heavy mf/hf sections are removed.
This means that La Scala IIs have to be moved very carefully, in order to avoid warping, bending, or cracking anything.
Why the difference in weight between the original La Scala and La Scala II? Is there a difference in sound?

Where do you connect the wires on a AA crossover?

Didn’t they ship with small round metal feet (sliders)?If they did it looks like the original owner at some point added extra pieces of plywood with plastic feet on them. Here's the bottom.

Yes I did. I just got them home! They look fantastic! I would love any information that may be available in the log books on them. An interesting twist of fate is that it turns out Joel used to perform regularly with the LA Philharmonic at the same time my wife's grandmother was a cellist with them. So in all likelihood he knew my wife's grandmother.-

I have a pair of LSBR La Scalas and one of them is missing the plastic feet. Are they available for sale somewhere?

Yes. Although a horn-loaded sub may be ideal, any reasonably powerful sub will do a decent job. With my bi-amped La Scala IIs, I’ve used a 500 watt 10” ported sub, an 850 watt 10” sealed sub, and now two 850 watt sealed subs. All three setups sounded fine. Sure, the more powerful subs do a better job, but your needs will depend on the size and acoustic response of your room, the type of music you listen to, and how loud you like to listen to it.
Thank you! The SVS is extremely powerful, with 1500 watts continuous and 16" driver. It's going in a large room but I won't be listening too loud. I just want the sub to be transparent and fill in the bottom octaves. -
I see a lot of people talking about using a horn loaded sub with the La Scalas. But I don't see any commercially available and don't want to make one. Would a sub like the SVS SB16-Ultra work well with the La Scalas?

Congrats on finding a pair close to you. The La Scala’s are special speakers. The value of those speakers is what you are willing to pay for them. You could probably find a better deal if you are willing to wait. That could be weeks, months, or years. In my opinion, life is too short for that. Enjoy!
Thank you so much! Words of wisdom right there! -
There is quite history to these speakers as well. They were owned by the longtime bass player for Johnny Carson's band. His widow has been hanging on to them for many years.

Lovely. Enjoy. Nice that they are relatively local to you.
Thank you. She agreed to take $2400 for them. One of the speakers has some relatively small nicks on the front of the woofer folded horn. Right on the front edge. What would it take to make those disappear?

How close was it? Mine is about 15 - 20 ft away.
