I just built my first 4Pi prototype and it looks bigger than i thought
I'm having serious WAF problems

I could try moving some furnitures and/or choosing a proper color/veneer for better integrating these 'refrigerators' (this is how my wife calls them! hehehe) into the room

Or I could try to make smaller boxes

Without changing components and keeping the standard crossovers, what would be the minimum box volume for getting a working 4Pi?

Omega Pro 15 works in boxes from 2 to 3.8 cu. ft.
Does it mean that I can do a 4Pi in a 2 cu. ft. box?
Will it sound close to the original?

Thanks!
