I am looking to upgrade my current Marantz M-CR611 integrated CD/amp with something else. There is a function on this unit that allows you to set a low frequency cutoff for the stereo speakers. This is useful to direct those frequencies to the subwoofer instead, which has a separate output that's not affected by the setting. You can then set the high cutoff on the subwoofer to suit.
See the manual page below:
I would assume that this would also improve overall sound quality as the stereo speaker woofers would vibrate less due to producing less low frequency content and thus produce less distortion, but I haven't done much testing specific to this myself. I don't see this function available on other stereo amps, even Marantz ones. Where most amps have a dedicated subwoofer out they appear to have a high pass filter that only directs low frequencies out the subwoofer output, but don't cut those low frequencies from the stereo speaker output. While the Yamaha R-N803 YPAO function seems to do something similar automatically, I can't find a way that you can set this manually.
I know you could do this by routing the stereo speaker cable through a subwoofer that supports it, but that introduces speaker cable placement issues. Am I wrong to assume that this function helps through less distortion? Why wouldn't other stereo amps have something similar to this function? Is there something that I'm missing?
