I think of a La Scala as a augmented PA speaker. 70 to 17,ooo hZ. with the drivers from the 70's and early 80's, models later on had much superior tweeter and improved mid performance. I loved LA Scala for small discos. Just combine them with either two MWM-s or Double 18" subs from Gauss, Altec, or EV. The MWM used a lot less power if we had the space. We used two MC 2200's or MC 2205's. One for the 4 La Scala and one for the two MWM-S, with 35 HZ high pass filters on either the Urei or Rane equalizers. We used a Urei modular crossover with the frequency set at 70 cycles with a 18 db per octave slope to protect the Klipsch woofers and to keep the MWM from color ing the La Scala upper bass and lower midrange produced by the woofer. I consider anything above middle C as midrange. 261.63 HZ. I wish Klipsch midrange horns were long enough and big enough to reach that low. I much preferred the sound of a La Scala to an A-7. Yes the La Scala didn't have the bass potential of the A-7 but the over all sound wasn't colored like an A-7 either. Just throw in a supplemental woofer and the La Scala combo could easily out perform A-7. The A-7 was basically a small theatre speaker and did not produce highs that well or bass below 50 HZ either and the midrange sounds around 500 to 1 Khz were so colored. So except for PA uses the A-7 need subs, too unless stuck in a big corner and then you might get down to bit below 40. When we had to reinforce guitar or other musical instruments in concerts and the Symphony guild wanted an intimate sound I much preferred La Scala and for less dynamic instruments Cornwalls over A 7. And they looked nice. I would always stack either La Scala or Cornwalls with the top unit inverted, for amplifying, Concert Harp, 12 string Guitar, solo violin, viola,, or Cello that needed help. One time They needed help with a Solo Bassoonist, and the two Corn walls performed with great realism with very little effort . A7 and bassoon=. four letter word, four letter word and more four letter words. So I admire the little La Scala. I would never be happy with it in a home as a stereo speaker, but as a sophisticated PA Speaker it was a great performer. We use to use two or three at Comedy Playhouses depending on the design of the stage. Oh another instruments that La Scala worked great with . Banjo's and Ukulele . Who was the entertainer who played the Ukulele, and I'm not thinking of Ted Mack, that's a name out of the Past. One of the Smother Brothers or was it Jerry ???? Van Dyke.
La Scala were perfect for barber shop Quartets, too.
