Yeah, you heard it right---BOTH of my 210XLT's crapped out within 3 weeks of each other (both are also over 5 years old). Specifically, the speakers in one "appear" to be blown judging from the distortion and the other one "may" be (just dropped them off yesterday with my tech). The tech tells me that I'm killing them by playing the low B stuff with my fiver, and that I "really should get a 15 cab and bi-amp it". Is this hogwash? I'm usually playing smaller to medium-sized gigs using only 1 210XLT and sometimes I'll add my Ag GS112 and evrything has sounded great. I'm powering the cab or cabs through my DB750 and I usually alternate between several vintage p basses that I own and my Elrick 5. This tech suggested that I get a 15 cab and then buy a two-way crossover so that I can send all the lows to the 15. Now I'm horribly confused----what to do?
