Altho there has been a lot written about the so-called "double bass", I would like it as a selectable feature. I just read a magazine review about a receiver that has "double bass" as an option!! One can select either:

a. full-range signals go to the main channels and the subwoofer gets all signals below the cross-over point plus the LFE channel, or

b. only signals above the cross-over point go to the main channels and the subwoofer gets all signals below the cross-over point plus the LFE channel

No fair arguing about "why would anyone want it" "defeats the artistic intent of the creater" ..... and so on.

I have that in my relatively old analog processor, and am not happy about giving it up when I upgrade.
