I have the gain on the LFM-2 set just an eyelash beyond the mid-mark (12 o'clock). I'm bypassing the sub's crossover and using the bass management feature on the rear of the RR2150 set at 80Hz. Bass trim pot is set at neutral and speaker EQ is off. I'm not real technical, so I thought it best to leave everything neutral coming from the 2150. It sounds so good, I haven't fiddled with settings since initial set up. Any suggestions?
