Henry_chinaski: I set them up myself. I should've made it clear that I bought them used here in New Zealand. I have tried different positions, but hasn't helped.Adjust speakers according to midbass energy (if you haven't already). Start by bringing them close together (~35% of room width, centre of woof-to-woof) until you hear bass energy, not muddiness.
Then start playing with toe-in carefully focusing on upper-midrange reproduction quality. (i.e. if the sound is "hard", spitting, hi-end ear-piercing, you're off.)
Normally, you should be able to get a reasonably seemles sound with some low-mid /upper bass prominence.
The spkrs go loud with low distortion -- but NOT very loud (distortion starts setting in + the required energy fm the amps is high).
The 7,2 are nice spkrs -- but I heard them on the fly, and certainly not in comparison to the SF. Can't say much. They weren't playing very loud either, I assume by owner's choice rather than ability... Cheers
