spoke to a few rig lads about this last night and their advise was to buy a 2nd hand pair of high end monitors that are ****ed. that way you get them cheap and can learn whats inside them while at the same time research the best upgrades for the new parts.

you have to remember that casing design is a big part of the overall design. companies like mackie/adam etc spend stupid amounts on design already so at the very least, if you bought a fuked pair, you'd have a pro casing.. which is a good start.
