      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.

    Terry London, Home Theater Review
    "the Sigma OB can be driven with as little as eight watts, yet it can create soundstaging that rivals the best large planar or electrostatic panel speakers, but with much more accuracy in the location and size of players. It also has great lower-end bass extension; bass is tight and has great slam. Finally, these speakers render tonality and details of the music in a relaxing, natural way. [T]he whole time I spent reviewing the Sigma OB speakers, I kept thinking that these speakers have all the spatial virtues of big panels but add accurate sizing of players, along with chest-thumping bass and dynamics."
