so i ordered my Avatar 2x10 neo cab which should be here in a couple of days. my plan with this was to get the 2 10s instead of a 4 10 cab which is what im used to. i was thinking about getting more lower end as well. i went with the 2 10s which are 600 watts rather than the 1200 watt 4 10s. im using an ampeg br4 which can power two cabs at 500 watts each. once the cab gets here im going to play around with it and from what ive read it will probably be up to par and ill order the second half of my short stack. the question is, should i go with a 15 or a 12? i prefer a lot of punch in my sound and 15s sound a little bit slow to me but ive never played through a 12. i was looking at the delta LF 12 which is 500 watts. has anyone tried this? also if i went with a 15 at 300 watts do you think id have a problem with too much power going to that speaker?
