I'm looking for a 5.1 sound system and there is sooo much to choose from. I've found 4 I really like, but I have a few question to ask before I make the decision.
1. I hear all this stuff about Dolby Digital and DTS hardware decoding built in. All the expensive sets seem to have this. The thing is I already have this stuff in my computer (It comes with Realtech HD audio Manager) So does my sound system have to have it, or am I ok as long as I have the software?
2. Whats the deal with this THX stuff. I know what THX is. It means the sound system is capably of theater like sound or something like that. The thing I want to know is if it's worth it. I sit 2 ft from my front speakers, 2ft from my back speakers, and 1 1/2 ft from my sub-woofer. Is THX worth it for me?
3. Which is better. A down-firing sub, or a forward firing sub?
4. How can I tell if it's a GOOD sub-woofer?
In case you're wondering here are the systems I'm looking at:
-Logitech Z680 5.1 Computer Speakers
-Logitech X-530 5.1 Computer Speakers
-Logitech Z506 5.1 Surround Sound Speakers
-Logitech G51 5.1 Surround Sound Speaker System
Thanks for the help!
