Mr Raptor .It sound to me you want to hook up to HOME stereo to your PC
Soundblaster live should do.
I have Cambridge soud design 4 speaker set up
with sup woofer. They are great for clarity suffice most time.
hee hee
BUT.....
When I want to FLY INSANE.......Then on my desk is BOKA 2000 w/sub woofer w /2 speakers hooked into my Juster sub Woofer w/2 speakers .....the Juster unit has a input line in the back.
So I have BOTH SETS running BOKA for BASS ....Juster for HIGHS .....each indivually tuned by the SUB WOOFERS....HEE HEE... and volume controls WOW !!! hahahahaaa!!
When I go to single missions the screen where they start the WULFs up in the hanger??.......MY desk shakes!!! and when pilot shuts it down you can hear the individual Cylinders fire down to a HALT
WOOOOOOO BOOOOOOY
And were not talking going DEAF either just got BIG BASS sound not Volume wise !
good , old fashion, feel the wind out of the woofer BASE!
and FLAK.....dont get me started

I use Cams 99% of time but when NOBODYS HOME heeee heeee
and Ive had too much coffee
