Thanks for the detailed reply. The construction looks good. I have no experience with listening to these type larger high efficiency speakers. I am certainly curious, but over hear in Canada I don't know anyone or any place where I could hear something like what you have.
As for the construction choice of materials for the cabinets, it looks like a type of particle board, was that your choice? Or part of the Hiraga design.
I've heard a few of Jeff's Cessaro's over the years at shows, but like most shows they are never truly optimized. But the first time I heard one I was very impressed and Ralph from Cessaro is so cool and down to earth.
I have a Horning Eufrodite and like it, but there is something very appealing about large drivers making music if you have the room to accommodate.
I see you're no longer using the big Hornings. Can you provide any more details on your new speaker. Long time user of Tron and TW and High Water Sound customer and friend.
