It matches the La Scala's [fully upgraded] in a spectacular way.
The La Scala's received new 15 inch cast-frame woofers, new wooden midhorns, new crossovers, and new high-[er] end tweeters.

In a few weeks I'll get a visitor here who writes reviews about stereo-gear and publishes these in audio-magazines and on the internet; he said "he just had to hear this strange install himself"..

Everytime I tell my wife "this is it"...she knows I'll be changing something within a few weeks.

And if you like it LOUD....this is it!
