In article 3be9289f-24e9-47e7-aea8-
, says...
I know that the sub plays only the low frequency sounds. Is it
possible that a CD played on the DVD won't have the low frequency
sounds?

Depending on where your crossover is set, it is entirely possible that
the music you are playing won't go low enough to require the sub.

Do you have any movie DVDs? Rent an action movie or something like that
- it will have loads of low frequency information and you'll know if the
sub is kicking in or not.

BTW, when I first set up my home theatre I had the same concern as you -
it seemed like my sub wasn't working. I had the crossover set pretty
low, which generally isn't a good idea unless you've got very bass
capable speakers (which you don't).

You probably should be running with your crossover set to 80 (set this
in your receiver). If your sub has a crossover, set it to the maximum,
or by-pass.
