I've got a vintage stereo system (pioneer sx1250) as my primary sound system
and an Audio Source ss5 decoder for my surround sound. I run my dvd player
through the ss5 and then to my stereo. It seems to be working well for me.
I only use the surround sound for dvds. Other music sources I run straight
through my two primary channels only.

I don't have a subwoofer and I'm thinking about adding one. The ss5 has a
subwoofer out but a subwoofer is one thing that I'd probably like to also
use with other music sources.

So my question is does the dolby surround sound actually have a specific
subwoofer component? Or is the ss5 just picking off the lows and feeding
them out the subwoofer connection? In other words do I need to use the ss5
subwoofer output to get the maximum surround sound effect or can I just feed
the subwoofer from my front two channels after the ss5? TIA.

Subwoofers didn't come into common usage until the "Home Theater"
became popular. For music listening, the subwoofer range of sound
wasn't necessary but when folks started watching movies the sound
effects like explosions contained a lot of very low frequency noise at
very loud levels. This kind of sound drove most speakers crazy
because reproducing music didn't make such high demands on speaker
systerms bass sound.

The audio tracks of movies don't contain a subwoofer track. The
subwoofer output is generated by the Audio/Video Receiver from the
surround tracks of the movie being watched. You don't NEED a
subwoofer if your Left/Center/Right speakers can reproduce decent bass
frequencies, however, just because of the example I cited in the
prev. paragraph, a subwoofer is very desireable in a 5.1 home theater
system, the ".1" is the subwoofer.

A subwoofer is a loudspeaker that extends the range of a system downwards.
Low Frequency Effects channel in movie mixing is a somewhat different
concept.
