While of course DTS or DD is the preferred format Many of my 'digital' cable channels broadcast a Dolby 2.0 signal, which I use traditional Pro Logic to decode into surround. I know the center channel is culled from the two front channels by taking the shared information from each channel and matrix's it into the center, leaving the uncommon info to each respective front. And I know the rear channels are derived from the fronts through some out of phase voodoo that I'm not sure I completely understand. But where does the bass track(sub-woofer) come from? I'm sure its a set crossover in the decoding that sends low freqs to the woof, but what is that freq?
With the cheap sub I have...won't mention any names(mainly from embarrassment), it rhymes with yolk...oops..I slipped, Ican't really handle some of the lower freqs found in DTS or DD without turning the woofer WAY down..of course losing the original impact of the flick. But with music and Pro Logic decoding its not so bad. I figured if I could set the x-over as close to the PL standard as possible I might get better over-all response from the shoe box in the corner.
Or am I totally whacked in the head? I'd still, just for curiosities sake, like to know.
