A/B them with your current monitoring. I hate to sound harsh, don't think I'm b**chin at you, but book smarts ruined production. On paper you're supposed to have "flat" monitoring, an amp may "color" speakers more than "real monitors"(notice the quotes).
Things I've learned. Larger woofers give a way better bass response. Higher wattage gives you better perception of peak volumes, I have no problem taking "a little coloring" in return for the ability to pop my CDs in my car or get them played in a club without any surprises. Until I can afford professional powered monitors that are at least 200W each with 8inch woofers that surpass the sound I currently have, I'm very happy with passives and hifi/bookshelves.
2 Questions.
1. What year were powered monitors introduced and what was used in professional studios beforehand?
2. What will your final product be played through?
Give them a shot, that's all I'm asking you to do, play some old stuff you make on those lil' crapboxes you got hooked up now(NO OFFENSE)if you can't get a better perception of everything in your mix through those huge beautiful speakers running through an amp, you log back on and call me the biggest stupidest idiot to ever post nonsense up here and I will take bake everything I've ever said about speakers outperfoming monitors!
