      Had my Sigmas for over 3 yrs now & have thoroughly enjoyed them. Coming from Apogee Duetta Signatures (15 yrs) I had grown to love open baffle sound. If you have enough room to get these 5 or 6 ft off the back wall you’re likely to love these. My only suggestion is get a sub (or better yet a pair of subs) to really flesh out the bottom end if you like the fuuuuull range sound. You just have to move a bit more air than these can accomplish (but I am spoiled). They blend beautifully with a pair of Hsu Research 10″ subs & my room is the equivalent of a 3 car garage. My-o-my, the openess, air and definition, without edginess, is wonderful! Careful placement of the subs can give you a most delicious low end and between all 3 amps I’m running nearly 900 watts so definition is remarkable as the system coasts along.
