lesc Posted October 17, 2004 Share Posted October 17, 2004 hi i am the proud owner of a set of pro la scalas with the aluminum edging and fiberglass wood. i also own a set of normal la scalas. i have all the info i need on the regular la scalas.(they are type aa x-over and look like they were on tour for years and years. which gives them character and proves they are tough and durable.)but i can find almost no info on the pro la scalas. they have a higher power rating and the woofer is different. they are two seperate pieces with the x-over in the tweeter/squaker section. the serial number on the side of this top section is 1852. i want to know as much as i can about the x-over and specs. they also have on them a different dbl rating at a different distance than my regular ones. i am curious about all this and can`t believe someone hasn`t posted more info about these speakers. i really love them and am presently waiting for another set i purchased on e-bay. but the set i am waiting for has no woofer section with it. so i will have to search for a set of woofer section or buy some other type to go with these. i picked klipschorns as my dream speaker about 25 years ago. i am a grand father 10 times over and am finally going after my stereo upgrades. the pro la scalas are not klipschorns but they are more versatile and can take more power and they appear to be almost indestructable in the aluminum and fiberglass. also sidewall resonance in woofer section is none existant.but most of all they look like they are tough. a good match for my all go little show stereo set-up. if anybody has info on these speakers i would really like to know. it just amazes me that so little info about these are available. but there is probably some reason i am completely unaware of. thanks for any and all help. les cornell ps.i am wanting to know what upgrades i can do to these speakers/x-overs and any options other people have used to improve these speakers both the typa aa la scalas and the pro la scalas i own. and can anyone tell me where to get plans to build the klipschorn bass bin. that is the only difference between the la scala and khorn right.

khorn58 Posted October 17, 2004 Share Posted October 17, 2004 I was watching the Pro lascala top you won on eaby. was hopeing no one would bid as they were a bit on the high side price wise. I won a pair of top just like thes last yerar on ebay for 250. I found a pair of botom right here from a fellow Klipsch Forum user. All i did was post want pro lascala botoms.I think the botom are a lot harder to find than the tops. you could buy as bet up stock cabnet and modifi it. I think i have some orig klipsch lit on the orig pro line from the late 70's early 80's that have the specs. If you look closer at the db rating of the pro line you will see they use a diffrent distance to messure Dbs If you convert it is the same as stock. These top work well with other bass bins from peavey Altec ect. Looking at my crossover i think the only diffrece form stock was the added Fuse and Bi amp hookup. Ok I just read a orig La Scala Pro Broucher. The y show crossover as the same as stock but with the added fuse.s ect. they also show how to hook up a stock La Scala for bi ampping. Freq response 55Hz-17 Khz -+ 5 db SPL= 1 watt 101dbs max 127 dbs at one metter not 3 feet like stock max power 200 watts There is alot more info with sound patterns and charts ect. Finsh are stock painted black or with all trim or fibergls coat with trim in both one part or to part. hop this helps. I have a first year pair lascal (early 60's) if you want info on them they have Horizontal bass bin with open horns on top Quote Link to comment Share on other sites More sharing options...
Hurricane Mountain Stu Posted October 17, 2004 Share Posted October 17, 2004 Lesc, I have a client (church) that has 6 LF boxes and 4 horn cabs of the La scalas you speak of. I am not very knowledgable about Klipsch products but have many years experience in pro audio. If you will be patient with me I can provide you with pics and specs on these items. These speaker cabinets are fully functional (i have to check the tweeters yet) so far. All boxes are in immaculate condition. You would think these babies are walking off the show room floor. NO LIE. If you are looking for some speakers I am trying to talk them into selling and they are leaning on it. Let me know. I will get some pics together for you tomorrow and specs on thursday. Let me know.

lesc Posted October 18, 2004 Author Share Posted October 18, 2004 khorn is there any way for you to send a copy of the original specs or brochure you have. it sounds like there are some differences i would like to know more about. and thanks for the info you shared. it is a great help, with these being out of production it seems to be hard to find the info you have. to be able to use these speakers right i will need to know all i can find out. you were watching that auction, small world we live in. i probably paid to much for this set. i would like to hear more about the early la scala`s you have. like were the specs the same and what about x-overs any change there. i seem to have read some where that the woofer access was also changed on the early la scala. if you can`t send a copy maybe you can post a word for word account on the pro la scalas. i actually like the finish on these. and does it show the x-over being the same as the home la scala. seems like it would be stronger. with the higher power rating and all. thanks again for your time les cornell Quote Link to comment Share on other sites More sharing options...
lesc Posted October 18, 2004 Author Share Posted October 18, 2004 hi hurricane or stu, absolutely please let me know if these speakers become available. pictures and full specifications are always good, what kind of price do you have in mind will you sell by piece and if so are any of the serial numbers sequential on the speakers.or is it a buy it all or nothing kind of deal, are they all the same age and condition and will this affect pricing also are you selling with a guarantee to be in good working order or is this a as is kind of deal. lot`s to think about. so let me know, i am definitly interested and am a la scala fan for life. this is for my home stereo so it is not a commercial application. the industrial la scala sells for less than the retail version. that is what i have read somewhere on this forum. i am no expert but the guys around here are very knowledgeable. also if you can find the age and history of these speakers it could help your cause. tell me something about yourself if you don`t mind. i always love to hear peoples stories. thanks les cornell Quote Link to comment Share on other sites More sharing options...

So some people replace the pro woofers with a "hi-fi" K33 if it's for an indoor hi-fi use. powerful enough I think the cross-over is basically the same except it's been splitted in two. differences in sound should be very marginal...

Marvel Posted October 18, 2004 Share Posted October 18, 2004 I believe that the Pro line used/uses a K-43. Also, from djk (I think -- I save way too many things on my hard drive): The Klipsch K43E is made by Eminence. If it was made in the last couple of years the power handling is much higher than older versions. It is somewhere between a Kappa Pro15 (500W) and a Kappa Pro15LF (600W) as far as power handling.

khorn58 Posted October 18, 2004 Share Posted October 18, 2004 lesc , When i find some time i make a copy of the broucher and post it. Your lascala top look like the early version around 1980 give ot take a few years. Theyb orig had the k43 made by Gause(not shure on my spelling) at the time this drive was the pro standard being able to take more power than any other speaker of its day even jbl altec and ev. BTW I am looking for some orig k43 drivers from around 78. I just compared my pro crossover and it is just a modifed stock one. Quote Link to comment Share on other sites More sharing options...

IndyKlipschFan Posted October 19, 2004 Share Posted October 19, 2004 Gill your amazing, I hunted it down!! Like always, a class act, and a treasure trove of info! http://forums.klipsch.com/idealbb/view.asp?topicID=37487&sessionID={AD9E05DC-899F-44C5-B4DC-7C14477E0B6D} Quote Link to comment Share on other sites More sharing options...
lesc Posted October 19, 2004 Author Share Posted October 19, 2004 now that is a lot of info. it seems there are different specs for different years. and a real difference on spl rating 119db to 127db that is a big difference. but i am happy to learn my set is a bg type set. i plan to have these for life. i tried calling klipsch and the rep said the industrial had 127db and the crossover was al-3 type. i guess nothing in life is ever really exact. these la scala`s have serial numbers but i don`t know if that will help in my search. and i absolutely have to thank all of you guys for sharing your info. i know much much more than i did. thanks les cornell Quote Link to comment Share on other sites More sharing options...
psg Posted October 23, 2004 Share Posted October 23, 2004 I have a product catalog from the Canadian distributor dating from ca 1980. The catalog has both my Klipsch and Nikko Alpha 220 power amplifier, which reminded me how I was introduced to Klipsch: The store where I got my amplifier had Klipschorns, La scala's, cornwall's and Heresys in the same room! Anyway, the catalog has two pages on Klipsch, including the mcm 1900 (huge thing with 2 15" drivers yielding 124 dB at 3 meters outdoors), La Scala Industrial and Heresy Industrial (looks like a stage monitor). The specs on the La scala are numerous, but i'll summarize with: SPL 96 dB at 1W and 3 meters (Note this is much further away than the typical 1 m) SPL 119 dB at full power (200W) at 3 meters. Frequency response: 42 Hz -- 17000 Hz +/- 5 dB measured indoors 60 Hz -- 17000 Hz +/- 5 dB measured outdoors at 10 meters, 1 meter above ground level. Drive components: Woofer: 15" K-43 Midrange: 0.7" K-55 (K-400 horn) Tweeter: K-77 horn tweeter Hope this helps. I could scan the pages and email them to you if you want.
