Here are some answer that you should ask yourself and the salesman, when you are going to purchase a home speaker system.
1. What Do I need to
play Dolby Digital Surround Sound?
2. Placement of the Subwoofer?
A subwoofer produces tones that are deep so the human ear is unable
to pinpoint their location, which is why conventional wisdom is to put
the subwoofer anywhere you like. However all rooms have what is
called a "sweet spot" where the subwoofer sounds best, so when you are
setting your up your subwoofer play something with heavy bass, like
(300 Spartans) move the subwoofer around the room, return to your
listening area to see how it sounds. Once you've pinpointed the "sweet
spot" make notion use other people to also help in pinpointing.
3. 5.1 vs 6.1?
The addition of one speaker behind you or two on the side make a big
difference, The traditional 5.1 surround sound speaker system sounds
very good, but leaves huge gaps in the sound area behind you and on
the sides as well. The more speakers you have to fill these gaps the better
your sound experience will be. The only drawback to this right now, is
Creative Labs is the only manufacturer selling 6.1 or 7.1 speaker systems
The T7700 named Megaworks and Gigworks, and Creative Labs S700 5.1
system which is upgradeable to 7.1 for an extra $100.00.
You will need a soundcard that supports 7.1, which there are several on
market and more coming. Click Diagram to see examples of speaker
