Thanks for the help guys. I'm looking for mixing monitors.
But the reason I want 8s is because I wanted something in between a large sound and a small sound, to round things out. First off, of course I want the flattest frequency response I can get. I wanted 8s so they were not too far away from what most average consumer's buy, and also if I play my mix in some fancy smancy studio with damn 12s I won't be lacking, or overdoing the bass end. I picked 8s because there are like a middle ground speaker.
I do appericate your input, and will look into the disadvantages of 8 in woofers.
I can't say I understand or buy your Logic here.
A good monitor with 6" woofers will sound plenty big. Also, aiming for what the average consumer has would be something along the lines of headphones or crappy Bose type systems, neither of which would be any good for mixing and certainly don't resemble a monitor with an 8" woofer.
Also, I wouldn't consider most facilities that have 12" monitors to be fancy. In fact, I'd consider most of them to be ghetto. Very few monitors have 12" woofers built in and even fewer that are in production today. JBLs of yesteryear contained 12s and a few soffit mount speakers contain 12s. (Caveat- there are, of course, exceptions to this rule. However, I assure you that none of these exceptions fall within 10x the cost of a $500 pair of monitors.)
The vast majority of professional monitors will either be a 2 way based around a 6, 7 or 8" woofer or a pair of woofers in that same size range. A full range system can be obtained using 6 or 7" woofers and unless you have one hell of a control room, 8" woofers would likely be overkill and muddy at best.
I would far from consider 8" woofers to be middle ground. 5" woofers, yes. 6", maybe. Beyond that, we get into "bigger than average" and if a manufacturer must resort to woofer size to obtain low usable frequencies, they are likely doing something wrong. (Again, exceptions apply - notably Dynaudio BM15s, MeyerSound HD1, and K&H O300, O410...)
