I own ProAc 1.5's and am considering adding a sub. But before I do looking for people who have experience with 1.5 & sub combination or suggestions on filling the bottom end for about the same money ($1500.00) in a single speaker.
As a prior owner of the 1.5's, I would suggest that you look to speaker placement before making any further changes. Check out the excellent instruction on the Audio Physic website.
