i have jbl l-7s that i want to biamp but am a little confused.The jbl supplement for the l-7s say have your jbl dealer make a modification.i have 2 hafler dh 200s one to the lf and the other to the lf/mfs.this isa 4 way system.i guess the way i did it was a horizontal biamp and i believe it can be done vertically also.which one is better and am i screwing anything up with my hookup.i am using a rotel preamp with 2 outputs to the amps.appreciate any thoughts.i also have 2 hafler dh 500s that i would love to try but only with proper connections
