Theres one. But many have multiple subs. Why isn't there a designation for the number of subs in use?
2.1, 5.1, 7.1,....
One LFE signal....I get that but...
Why not 2.1(2) or 2.1.2 or 2.2/1 or 2.1+1 or 2.1x2 or...
I like 2.2.
I want 2.4.
We all accept there's only one LFE channel currently.
On that subject why can't other LFE channels be DSP'd? Surround information is pulled from 2 channels...Why not have heavier bass at the point of the explosion? If a gernade is thrown towards the viewer and passes of the left side of the screen why can't a rear left sub be given a few more db to give authority at that location.
IMHO this is where HT/AVR technology should be heading.
Life is good.
