I'd like to request plans for both the 1Pi and 2Pi (both regular and tower) speakers. As I understand it, the 2Pi both use the same drivers & crossover, just that the 2Pi tower is floor-standing with larger cabinet volume and thus better bass extension.
As much as I'd love to go with a 3Pi or 4Pi (I built the 4Pi about 17 years ago), I just don't have the space or the WAF for anything bigger than maybe a 2Pi.
