I have been using a pair of 2+2s since the mid 80s. I recently did an update on the interfaces (better caps, resistors, etc) and am even more pleased with the 2+2s. I recently acquired a sacd player and the speakers I am using for surround (as in movie soundtracks: explosions and other noises) are no longer satisfactory, so when I can get my hands on another pair of 2+2s or a pair of 1+1s, I will use them as surround speakers to reproduce music.
