back in the day when i first joined a band i started of with a carlsbro 150 watt head put through a 1 x 18 reflex bin (you know, the one where the speaker is back to front)
very bassy, not much treble, but that suited my sound at the time
am now playing through a hartke 100 watt combo, great for rehearsal and smaller gigs but am thinking of getting a more powerful head and cab/cabs rig
am thinking of getting a 4 x 10 for the top end and possibly a 2 x 15 for bottom, as i have used before and liked a lot, but am also considering a 1 x 18 instead
have read about lots of different combinations on here with 15`s,12`s, 10`s.......but dont remember 18`s being mentioned much (i have the memory of a goldfish though )
