Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Am I making a mistake setting up Bass Management?

I changed my config today to include my Sub in the Music section of Bass Management. I did that by setting my Fronts as Small, setting the crossover to 65Hz and setting the Low Pass Filter to 65Hz. For Video, the Fronts are Large and LFE goes to Sub. I installed this config on the 861.

As we know, there is also an LPF on the sub itself. I expected that while playing music if I changed the LPF on the Sub from 80 to 100, 120, 150 and finally Bypass, I would hear no change in the output from the Sub since the 65Hz DSP LPF should have been truncating everything above 65 in any case.

I was quite surprised to hear a vast increase in Sub output in Music mode as I changed the Sub LPF from 80 to Bypass.

The Sub is an analog Paradigm. What am I doing wrong?

The reason for my concern is that the same sub is also the LFE sub for Movies, so ideally I would like to leave the Sub LPF at Bypass and have all LFE directed to the Sub. I can't do that without remembering each time to change the setting on the sub as I switch between audio and video.

Thanks
