CECAA850 Posted May 3, 2013 Share Posted May 3, 2013 kg4guy, Have you ever measured the frequency response of this version? I am curious how different it is from the stock LaScala. See the top 2 posts on page 3. Quote Link to comment Share on other sites More sharing options...
kg4guy Posted May 8, 2013 Author Share Posted May 8, 2013 Also I didn't use K-43's in the larger boxes it would most likely been a bit better or even better Bob's cast frame woofers. Quote Link to comment Share on other sites More sharing options...
minermark Posted March 19, 2014 Share Posted March 19, 2014 I have a pair of JBL 2360A horns and 2445J drivers that might work nice also.[^o)] Amazing, that is exactly what im selling on ebay! the horns that is. Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted March 20, 2014 Share Posted March 20, 2014 New La scala bin What are the dimensions of the trapezoid (top/bottom). I want to model this in Hornresp. Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted March 20, 2014 Share Posted March 20, 2014 Yes it the same basic woofer chamber as the La scala's but I followed John Allens version. It was actually designed by Gary Gillum's son. Gary was the former chief engineer at Klispch and Associates. He is the designer of the KG2 (G squared for his initials) and the co-patent holder with PWK on the MWM woofer (Motengator). I interviewed Gary Gillum a few years back and this is what he told me. He left Klipsch and started bulding speakers for John Allen, presumably with Paul's blessing.

ClaudeJ1 Posted March 20, 2014 Share Posted March 20, 2014 Sides on. Looks like an 85 Hz. cutoff instead of 100 for a LaScala Quote Link to comment Share on other sites More sharing options...
drboar Posted March 20, 2014 Share Posted March 20, 2014 I have been playing around with various flares of a LaScala type horn. That is a horn about 1 m long and a mouth area close to 0.36 m2 Different flare shapes like exponential, hyperbolic and of different flare rates as well as chamber volumes from 30 to 80 liters. At least to HornResponse the differences seems small. The overalll horn response is set by mouth area and length not the exact flare (within reason) The chamber volume can be reduced to produce a sharper knee at the low pass and also reduce cone motion below the bandpass of the horn. I have my own ideas about making a La Scala light version with a curves and a twist added to it. LaScala does not have bass below 50 Hz but there is something about the slam of a large mouth horn...

longdrive03 Posted March 31, 2014 Share Posted March 31, 2014 Great build! Are you doing to vent woofer out the bottom? I assume that would extend low end response as well. Keep posting pics. Quote Link to comment Share on other sites More sharing options...
