i totally recommend the alesis m1 mk2 actives

i have got them - so have about four or five mates - we were all that impressed

they have got two amps and a crossover built into each speaker

don't worry about getting them loud enough - even set to half volume they can blow your hair dry (if you've got hair)

there's no point getting crap speakers just in case you play somewhere with a crap system

studio quality is good for mixing if you ask me - means you can really hear what you are doing and you can hear everything that is going on on the record
