Hey guys my receiver is as some of you know pretty old its a HK avr65 the crossover on it is non adjustable. I got my sub in but im missing some midbass from the mains. Can i run the mains at large like i have been and just use the sub's crossover for now until i upgrade my receiver? This should be the same thing ive been doing for the past few weeks just without the sub now i have it. Just wanted to double check before i did it thanks.
