On near-field placement? I have a pair of Alesis Monitor Ones (passive) and even though the brand name appears upright while on their sides, Alesis actually recommends that for optimum results, the speaker cabinets should be placed upright - with the tweet on top, centered directly over the woof. Even though they look symmetrical on their sides and appear as though that's the way thy should sit, (and I've used them this way for years with the tweeters on the outside, just like you would set up a pair of NS10's) I've tried this recently - for several weeks now - and while I haven't noticed any glaring improvement, they seem to be very accurate in this placement - (although I'm sure that all the recent acoustic treatment I've done in my mixing space has made a huge difference as well). What say you? Do you think it makes a difference? Pending of course that: A. You have decent monitors to begin with, along with a good sounding/treated room B. your monitors would be symmetrical in either position C. that you've positioned them to aim within the "generally" accepted 45 - 60 degree "sweet-spot" triangle How about it... have a preference? A reason for your preference?
