geoff. Posted January 20, 2019 Share Posted January 20, 2019 Acoustic foam in the doghouse... Definitely not a cost-cutting measure. I feel an LS mod coming on! 1 Quote Link to comment Share on other sites More sharing options...

I'm pretty sure they know what they are doing 8-) The La Scalas do seem to hold up. A pair of 1974 black-painted La Scalas (modded only by having Crites CT125 tweeters and Sonicaps installed) serve as surround speakers in my system, while a pair of 2007 Lacquered Walnut La Scala IIs (upgraded to 402 JubScala II spec) serve as main Left and Right speakers. The ‘74s have a few scuffs, as you would expect, but the ‘07 LS2s are near mint. All four sound great. Does anyone know what has been changed for the new AL-5 ME version?

Panelhead Posted January 20, 2019 Share Posted January 20, 2019 Not sure all the changes. These are definite. 1.Crossover 2.Tweeter and HF horn 3.25 pounds heavier than LSii. 4.Binding plate and internal wiring. The top is supposedly made of 1 inch up from 3/4 inch. I would not think that added 25 pounds. Maybe half that. Never looked, but if LSii top hat is plywood and these are MDF that might be 25 pounds per speaker. I watched the video. Seeing the sheet of open cell foam being stuffed in doghouse is interesting. I want some in my LSii. Can only think this is to damp a ringing that have found with measurements. Whether acoustic or done with an accelerometer. Quote Link to comment Share on other sites More sharing options...

Heresy ii's, Forte ii's and iirc my Chorus ii's do as well. The foam that I have seen so far seems to be fairly standard and inexpensive.

Islander Posted January 21, 2019 Share Posted January 21, 2019 The usual purpose of sheet foam in a speaker cabinet is to add “virtual volume” to it. It gives the effect of a larger cabinet, without adding size or weight. As well, the engineer designing the speaker can easily experiment with the amount of foam until he or she is satisfied with the result.

In practice, the number of female speaker engineers is very small, maybe even close to nonexistent, which is why I went with just “he”.

Their prices were very fair. I also need a pair of Chorus passives and will be ordering Forte III passives, per chief Bonehead I believe, as replacements. 1 Quote Link to comment Share on other sites More sharing options...
