Moderators Youthman Posted April 13, 2016 Moderators Share Posted April 13, 2016 Thx Mustang. Just curious...it says LaScala was made from 1985 to 2005 but I believe my LaScalas are 1980. 1 Quote Link to comment Share on other sites More sharing options...
Karsoncookie Posted April 13, 2016 Share Posted April 13, 2016 Should that link be possibly like "pinned" somewhere or sumptin ? Lars Quote Link to comment Share on other sites More sharing options...
babadono Posted April 13, 2016 Share Posted April 13, 2016 .it says LaScala was made from 1985 to 2005 Yea that's a definite typo. Maybe '65 or '55. Purchased mine brand new in '77. Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted April 13, 2016 Moderators Share Posted April 13, 2016 Just looked at the LaScala II page on the Klipsch website and it says "The original La Scala was unveiled in 1963 and named after the Teatro alla Scala in Italy. Cosmetically improved over the years, the La Scala II provides Klipschorn-like performance from a smaller cabinet that does not require corner location."

mungkiman Posted April 14, 2016 Share Posted April 14, 2016 Thx Mustang. Just curious...it says LaScala was made from 1985 to 2005 but I believe my LaScalas are 1980. I think you were instead looking at the Heresy II specs. 1 Quote Link to comment Share on other sites More sharing options...
jjptkd Posted April 14, 2016 Share Posted April 14, 2016 I noticed the Chorus crossover points seem to be switched between the I's & the II's. The Cornwall II power rating seems off as well, peak power handling of 1000 watts like the Chorus? 1 Quote Link to comment Share on other sites More sharing options...

jjptkd Posted April 15, 2016 Share Posted April 15, 2016 I know you've showed me these specs before but for some reason I have it stuck in my head that the original Chorus with the k-600 mid horn was crossed over at 600hz and when they switched to the newer Tractrix horn in the Chorus II they upped the mid band to 650hz, same as the Forte II and Quartet? If you look at the specs for the Forte II and Quartet the mid frequency response is 650hz - 7000hz. It just doesn't make sense to me but maybe I'm wrong?

mustang guy Posted April 15, 2016 Author Share Posted April 15, 2016 If you could dig up a brochure or something tangible it would help clear this up. As it stands, all we have is what Klipsch provided... Quote Link to comment Share on other sites More sharing options...
WMcD Posted April 15, 2016 Share Posted April 15, 2016 (edited) This doesn't answer the crossover freq question. But: It is interesting to look at the crossover schematics for the Forte, Forte II, Chorus, and Chorus II. All are somewhat different in the midrange and elsewhere. Generally, the Forte and Forte II use a first order scheme while the Chorus and Chorus use a second order (or so) by means of the inductor . . . and also use a resistor. The model of autotransformer is different in the units. The Chorus schematic is rather dim and I can't determine whether the output is inverted or not. The acoustic output of the drivers are often not totally in phase at the crossover point and there is a choice of whether a dip due to this can be solved, or partially solved, by inversion. Overall, it seems to me that a fair amount of redesign was done as these four cousins progressed. The FR of the curves reaching the drivers are going to be different a bit and therefore the crossover freqs can be different, if slightly.
