I bought a pair of B212XL's a few days ago based on the recommendations on this thread, and I must say I am very happy with them so far. The vocal clarity is amazing and these can get really loud without noticable distortion, but what really surprised me is the huge soundstage. My previous mains (admittedly entry-level Energy CB-20's) were toys compared to the Behringers.
I don't think buying a third one for the center is necessary because of the huge soundstage the mains are throwing. I put them on my two subs flanking my 100" screen and voices lock on the center just right. Besides without an acoustically transparent screen, an LCR setup would not be optimal. I am now convinced that a center channel is unnecessary with speakers like these thanks to their controlled directivity horns unless you have a really large screen.
One thing I have noticed that these speakers have a dip centered between 5-7 kHz. These being PA speakers, the dip is probably intentional to avoid sibilance. I think this dip is partly responsible why vocals are so clear. I have attached the in-room response of the Behringers from my listening position (about 3 meters from the speakers). 1/3 octave smoothing. I have applied only a few cuts below 120 hz to tame room resonances. Other than that there is no EQ. My room is treated with bass traps on the corners and at first reflection points. The bass response is flat down to about 12 hz with the help of my two subs.
I have already sold my Energy LCR setup, and am enjoying my B212XLs. They sound great and are very revealing, but sometimes I find them sound a little flat for a lack of better word. Perhaps, the 5-7 kHz dip is responsible for that. What do you think?
