    Hi all,

    My front three speakers are M&K S-85's and there rated down to 87Hz. My amps internal crossover is currently set to 80Hz.

    In my estimations that leaves a frequency gap of 7 Hz.

    Therefore, do I set my amps crossover to the next level (100Hz on a Denon 3802) so the whole frequency is covered or should I just leave a 7Hz gap?

    I must say, I don’t like the sound of 'leaving a gap" but does having a 13Hz overlap matter if the crossover is set to 100Hz?

    Regards,
    Brad

    Hi Brad

    I´d leave it as it is. The cutoff frequencies are not brickwall filters, they´ll roll off to a certain extent. Might be a worth a try setting the amps cutoff to 100hz to see what you think though.:)

    If they're anything like my Pro versions, they will go below 87Hz. A frequency sweep on mine shows a fairly flat response with the crossover on the amp set to 80Hz

    If you are using the crossover in the amp, you won't have an overlap between 87 and 100Hz as the speakers will only "see" frequencies above 100Hz, everything below will go to the sub.

    Try 100Hz and 80Hz and stick with which ever one sounds better to you.
