try to save up and get a 8'' pair. If you don't you'll regret it later. IMO
yamy's HS80m or M-audio BX8a or KRK RP8.
make sure you spend at least half the money for acoustic treatment as well.
I've got a pair of Alesis M1 Active Mk2s, and I'm really happy with them. I wouldn't hold back recommending those
ive got the passive versions and they sound a hella lot different to the actives, my mate has the active ones as a back up set of monitors, and the actives are alot boomier, the passives i find are alot more balanced. still very good monitors for the price!!
What power amp are you using with yours dude?
