I've recently acquired a Fender Pro 400 Bass Combo, and would like to upgrade the speakers. I play a 5 st. and would like a "clearer, more articulate" bottom end. My bass tech suggested I put in an Eminence Legend BP102 and a Legend B102 - he said guitarists mix speakers in their cabinet all the time - that bassists are just a little slow to catch on! Both use the same wattage but have a different frequency response. What do you think?
