I have an Ashdown 300 MAG combo 4x10 i got for about 400$. Nice sounding and all, but i want a little more kick to it. I have settled on two choices. one 15'' or 2x12''. My band plays progressive post-grundge. More heavy-melodic stuff than grunge and some odd beats sometimes. I play a custom ricken jazz bass as i like to call it. Its basically a Jazz bass body with two rickenbacker pickups (neck and bridge) My sound is a kind of Geddy lee (Rush) and David Ellefson (Megadeth) inspired. So . . . what kind of speakers do you think a need out from what information i have given? . . . Also, the speaker brand is going to be Hartke.
