I can't wait to hear a comparison of the stock Wilsons compared to the modified Sony's.
I can’t wait to hear the comparison of the upgraded Wilson’s compared fm the Sony’s. 
It's probably going to be a real headache that will require counseling.
"Yeah, but the Wilson's don't
need a sub"
"Well, for the same money as the Wilson's, I could have a pair of Otica in their spot and the Sony's that are easy to carry around, and still enough money for Chic-fil-A."
"But they are cool... they have an 8" driver and Danny hasn't made a 2-way with his 8" driver, yet".
"But the Wilson's are nice and special, and I like owning nice things."
"Well, she's OK with me having all of these speakers, and I'm having fun anyway..."
The handy part is the SVS subs allow presets. So I can have a preset for the Sony's and a preset for the Duette. My Ayre VX-5 Twenty amp (which I absolutely LOVE - Zero Negative Feedback) has 2 sets of Cardas binding posts on the back. Besides, I'll have tube connectors. I'll be able to swap in a different setup in seconds / hit a preset on the sub...
I wonder if this will be a bit of a story where measurements don't quite tell the entire story. The 8" Scan-Speak driver in the Duette is no joke, and there's no replacement for displacement... but the narrower baffle of the Sony...
You see? A real headache. The struggle is real!
