I have never messed with the Sub before so I really need some help from the forum member here. I just ordered the LFM-1 B-stock last Friday. After reading the LFM-1 and my Onkyo TX-RS 500 owner’s manual, I have a question regarding the crossover frequency for my main speakers.

My receiver crossover frequency is from 80 Hz to 120 Hz and my main speakers are Klipsch RF – 35. The frequency response for these speakers is from 37Hz to 20 KHz +-3db. Because my receiver crossover only goes as low as 80Hz, can I disable the receiver internal cross over and use the LFM-1 cross over? I’d like to hear how it sound at 40 and 60 Hz cross over. My receiver owner’s manual does not mention anything about allowing using external crossover.

I have a feeling that I’m stuck at 80Hz .

Thanks
