I've been testing Anthem MRX 310, as I have always been intrested to try out ARC1M and compare it to Audyssey XT32.
I noticed some strange issue (bug?), or atleast would like to know if it works as intended.
My mains are bass managed and EQ'd to 40Hz.
Sub/LFE LPF is 120Hz.
I measured my system and noticed that there is higher bass output between 40 - 120 Hz.. I lowered LFE HPF 40Hz, and the curve was smooth and flat. Testing was done with 2 channel analog sweep.
To confirm this, I muted my active main speakers, left only subwoofer on, and there was signal going to sub up to 120Hz range. With HPF set to 40Hz things worked as I think they should with 40Hz crossover.
Why is it that? With 2 channel signal and 2.1 system with crossover of 40hz there shouldn't be going much over 40Hz to sub. And as I assumed that crossovers should handle what is put in to subwoofer, but is seems that only LPF limits it, and it is for all channels?
