Interesting, so the horizontal C-to-C of 7" or 8" is perceivable, bummer.
Since the speaker would be crossed to a sub at 80Hz, not much point having a woofer do 80-150 let alone the Accuton not being able to go that low.
Sigh, so the unfortunate answer is no it doesn't make sense

Strange, because I'm sure I'd seen other W-T/M designs

I guess most are either poor designs, or cross really low the the woofer.
