Hey, Tyll, just curious, have you ever heard the Focal XS Book?
So yeah, I'm totally revisiting this whole idea, especially due to the Cube's limitations. There's basically no easy way to introduce a sub, plus subs are heavy. So I'd prefer a pair of speakers that have a larger range than the Cube has -- in the near field -- preferably something comparable to the Quad 12L's, since that's a limitation I'm familiar with, and I know I'm alright with.
I'll be adding a table to the first post, might have to turn it into a spread sheet.
