Other panels didn't vibrate as I understand, just the back panel. If they had a .75 piece on the back panel, it didn't vibrate. This is why Roy came up with the little strut braces in there to help deaden the back panel. Interesting and I had a pair of La Scalas last year with somewhat thicker than normal wood on the sides. It made a noticeable difference in side wall resonance. There was enough more that it was visually thicker which caused me to measure just to see and it sounded just as good as a set of fiberglass covered LSI's I once had.

Coytee Posted April 13, 2019 Share Posted April 13, 2019 Yeah, evidently the big broad sides of the LaScala are its weak point... anything to stiffen them will improve things. I once heard the LaScala II's at the factory, was talking to Mr. Hunter about them and how (in my opinion) they (the II's) sounded like they had another level of bass added to them.... he said the original series had the same output it was just masked by the buzzing of the box.

Dave A Posted April 14, 2019 Share Posted April 14, 2019 I agree and drum thumps and organ music is pretty surprising especially since I use the K-43's in there. Quote Link to comment Share on other sites More sharing options...

Some speakers use the box resonance to fatten up the sound. The output from panel flex is low, but the surface area involved multiplies the level. I was thinking the 19 ply birch was 5 x 5’. Good stuff. I bought all mine at Home Depot. Doubt they stock it now. Quote Link to comment Share on other sites More sharing options...
