I am planning to try bi-amping my 4344 Mk2's. JBL recommends an external crossover at 290Hz. Everything below that goes to an ME-150, which is a proprietary driver that replaced the 2235 in the original 4344.
I will be using a 10W SET on upper three drivers. The output impedance of my particular amp is 1.5 Ohms.
What should I look for in the amp for the bass? Should I try to find one with a comparable output impedance to the upper range amp? Should I get an inexpensive/used pro amp with plenty of power? Suggestions?
