mtb Posted March 13, 2012 Share Posted March 13, 2012 dear sirs, thinking about a used pair of la scalas. just wondering what exactly the bass horn is? is it purely exponential, or a conical " rubber throat " ? whats the freq. cutoff of the horn? is it foreshortened? i'm asuming its a 1/8 horn. thanks so much Quote Link to comment Share on other sites More sharing options...
Quiet_Hollow Posted March 13, 2012 Share Posted March 13, 2012 It's kinda square shaped and a danger to small kids and neighbors. Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 13, 2012 Share Posted March 13, 2012 Horn is really only good to about 100Hz, below it acts more like a DR. Only dangerous to short neighbors, unless you turn them up loud, which is very easy to do. [:#] Quote Link to comment Share on other sites More sharing options...
RRFL Posted March 13, 2012 Share Posted March 13, 2012 It is a remarkable horn with a rubber throat that is actually made from wood. While it technically starts to roll off @ 100 Hz it will put the majority of speakers on the market new or old to shame. It is one of the most enjoyable and exciting speaker's ever and is extremely compact for the performance it delivers. The Lascala is eco friendly as you only need 1 Watt for wife friendly listening pleasure. For drunken parties it is the speaker that still works "the day after".

djk Posted March 16, 2012 Share Posted March 16, 2012 "It is a remarkable horn with a rubber throat that is actually made from wood." The Klipschorn and Jubilee have the so called 'rubber throat', the LaScala does not. What this means is that the initial taper rate in those two is a 100hz expansion, followed by a 50hz expansion in the Klipschorn, and a 38hz expansion in the Jubilee. The LaScala is 100hz throughout. The main reason for doing this is to make the horn shorter, although claims are made for less HF distortion (but never backed up with measurements).

RRFL Posted March 16, 2012 Share Posted March 16, 2012 What about the Belle I was wondering about the difference to the LaScala? Quote Link to comment Share on other sites More sharing options...

While it can be used in a corner (1/8 space) and take some advantage of that particular location for improved low end response as almost any speaker can it was not designed to specifically be part of a tridedral corner using the trihedral corner as an extension of, or part of the bass horn.

artto Posted March 16, 2012 Share Posted March 16, 2012 It's kinda square shaped and a danger to small kids and neighbors. FWIW, if anyone remembers the old Memorex commercials where Ella Fitzgerald sings and breaks a wine glass with her voice ~ (Is it live? Or is it Memorex?), well, it's neither. It's Klipsch LaScala! I have a copy of the press release somewhere. They pumped a peak power of over 1KW+ into an industrial LaScala. They claimed the resulting instantaneous SPL was something like 140dB. There was also a disclaimer and warning. "Don't try this at home. The resulting sound level will cause immediate and permanent damage to hearing and possible damage to internal organs". Why aren't we using these things in Afghanistan? Quote Link to comment Share on other sites More sharing options...

djk Posted March 16, 2012 Share Posted March 16, 2012 "They pumped a peak power of over 1KW+ into an industrial LaScala" Myth. They actually used a long tube aimed directly at the glass just off camera. An oscillator tuned to the resonant frequency of the glass applied the power. A compression driver drove the tube. Less than 100W was used. Quote Link to comment Share on other sites More sharing options...
