Scottsman Posted September 19, 2023 Share Posted September 19, 2023 I have a set from the 80's. Bought them for a song...someone needed new warehouse space for their stadium equipment and asked for $400 for the pair. I noticed that the new ones seem to have a spacer between top and bottom cabinets. Does this help? Should I be looking at this and what the heck are the made of? Also I see stands that people make on eBay...projecting them up and getting the older ones off the floor. Any mods I should be thinking of. BTW - they sound great for what I listen to - I love the jazz club vibe. Anything I should do to upgrade - but not going nuts here. Musician but only casual audiophile...living on budget.

Marvel Posted September 19, 2023 Share Posted September 19, 2023 The new ones come as two separate units. Quote Link to comment Share on other sites More sharing options...
hanksjim1 Posted September 19, 2023 Share Posted September 19, 2023 The best advice seems to be sure the crossovers are up to spec. @Deang on the forum has a factory approved service that rebuilds them properly. You may want to reach out to him (may take a few more posts to open your account to PM capability).... 1 Quote Link to comment Share on other sites More sharing options...
OO1 Posted September 19, 2023 Share Posted September 19, 2023 upgrading capacitors is roughly 100$ for a kit , you're on a budget so that can wait .if you're handy you can chop the tops off, with a track saw , 2 piece LS are pretty , 1 piece cabs not so much Quote Link to comment Share on other sites More sharing options...
nickyboy6100 Posted September 19, 2023 Share Posted September 19, 2023 Just listen to them for awhile before you do anything. Stock La Scala’s sound great. 7 Quote Link to comment Share on other sites More sharing options...

Deang Posted September 20, 2023 Share Posted September 20, 2023 I would just clean them up really good. The networks can be cleaned up too, and unless you smell or see oil (from the capacitors) - it is certainly something you can put off for a while.

Dr Morbius Posted September 20, 2023 Share Posted September 20, 2023 Marine grade plywood is pretty good quality plywood for a speaker. I didn’t know they were made with it. 1 Quote Link to comment Share on other sites More sharing options...

It's not the plywood bass bins without the tops that have tighter, deeper sounding bass. It's the new ones that have one inch MDF.

OO1 Posted September 20, 2023 Share Posted September 20, 2023 LSI marine plywood is 7/8 of an inch of dense wood 1 Quote Link to comment Share on other sites More sharing options...
Dr Morbius Posted September 23, 2023 Share Posted September 23, 2023 I would think 7/8th of an inch marine plywood is better than 1 inch MDF …………but I never did test them. 2 Quote Link to comment Share on other sites More sharing options...

The spacer is only for looks, like a Klipschorn Type B. Since the new ones are MUCH heavier, 2 pieces makes moving them easier. Do not raise the bass horn off the floor (2 or 3 inches is insignificant), consider pushing them into corners. The low bass is limited and the distance off the floor could raise the bottom limit even higher. I have mine setting on subwoofers, but .... subwoofers. There are a few worthwhile mods (PM me), but first, which crossover do you have? What are your serial numbers? If the sound is forward and out in the room, you do not need a cap upgrade. If its laid back and "calm" you should consider it. Here's a hint. Quote Link to comment Share on other sites More sharing options...

Almost 40 years ago, when I built clones of the LaScala bass cabs for use in a PA system, I noticed right away that these were needed. Adding them made a tremendous difference, and I think those in the picture are twice as thick as the ones I added. Quote Link to comment Share on other sites More sharing options...
OO1 Posted October 11, 2023 Share Posted October 11, 2023 this picture was only an experiment by PWK , PWK never implemented braces with the production units of the LS -LS I Quote Link to comment Share on other sites More sharing options...
