ricktate Posted October 5, 2021 Share Posted October 5, 2021 I would do Crites 4500 hz mod takes the load off the midrange driver......get a pair of his tweeters. I painted my metal horns with rustoleom enamel helps with sound I think also put a little dynamax type stuff on the. I made some ALKs a long time ago to much money nothing different in my opinion. I sold them...lol If you decide to veneer them run some screws into the side boards to stiffen up those. 4 top and bottom should do it. I use O-rings on my mid driver cause that washer sticks out into sound path. A friend has industrials with the k-43 and it doesn't sound right. Does anyone have any information on what the K-43 does to LaScalas?????? Quote Link to comment Share on other sites More sharing options...

If they sound "different" from a normal LS, well then, they are supposed to...... I have split Industrials and have had other LS with K-43s, and they sound fantastic. To my ears (and many others), even better are Eminence Kappa 15C woofers. 1 Quote Link to comment Share on other sites More sharing options...

I'll get the AL5s later, but tinkering with these will be fun. To be honest I don't know if it's a real desire that your beautiful vintage Lascalas should sound like a modern AL5 Lascala. There are so many recommendations and advice on what to change and improve. Of course, modern AL5s sound also very good out loud. Your vintage Lascalas sound especially good soft to medium loud. For example, if you like your Alnico K77s then keep them. I'm definitely keeping mine. All modern drivers and horns may be an improvement or modernisation. But my now 62 year old ears like Alnico. I have temporarily installed K77M in my 1977 LS because the original Alnico K77 are being restored, magnetised and new diaphragms. The K77M ceramic magnets sound much less emotional to me, and psychoacoustically this impression extends to the whole sound, not just the highs. At the very least, I would keep all the parts and compare them from time to time with the so-called improvements. 1 Quote Link to comment Share on other sites More sharing options...

LSI's are better sounding to me too. 1 Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted October 5, 2021 Share Posted October 5, 2021 Good luck getting your vintage LS to sound like AL5. Vintage LS are constructed of Baltic Birch, AL5s are much thicker MDF, but I'm sure you know that..... Quote Link to comment Share on other sites More sharing options...

(I'm just a wire hag that uses store bought direct burial low voltage lighting wire) Maybe I'm just a hag, my wife might agree. Regarding the 402/510....do a lookup on them. If someone puts "X" amount of funds into fixing up LaScalas but more importantly, are actively looking to distinctly improve their sound, then that is likely going to be the most significant single upgrade that you can do..... but it's not what I'd call inexpensive. Right now, I'd say you are dancing on the periphery of improvements. The 402/510 and actively biamping them is jumping into the serious end of the pool. If you ever get near Knoxville, you're welcome to hear what I'm talking about. (I have 1979 LaScalas and 402's so can do a side by side comparison after some equipment swapping) The spades carry the sound of the thicker wire nicely. If I had spades with a better metal, that would probably help, but these spades have worked just fine with my Heresys and Chros IIs. As far as bi-amping goes, I'll do that when I get the AL5s. Right now I just want to hear these old speakers sound new ++. Quote Link to comment Share on other sites More sharing options...

AA Crossovers. I'm impressed by the sound, even though I know an ALK crossover will take them to new and improved sonic capabilities. I have owned tons of Klipschorns and LaScala and the AA crossover sounds best to me of the older speakers. 3 Quote Link to comment Share on other sites More sharing options...

The amp sounds great on Fender Rhodes, too. 1 Quote Link to comment Share on other sites More sharing options...

The AL5s midrange has a 2" diaphragm, NOT a 2" throat. All the K-55 versions have a 1 " (more like a 7/8" throat. 2 Quote Link to comment Share on other sites More sharing options...
