I have my 4.1's in a dorm, and on either side of me are better systems...LOL On one side is a full dolby digital Acoustic Research 5.1 system ($1200+) and on the other side is a steroephile freak...let me tell you about him. He has TWO subs...each with their own amplifier. His big sub is HOMEBUILT from two 12 inch RADIO SHACK subwoofers. Before you laugh, and trust me, you wouldn't if you heard them... he has them set up in a Isoberic design, with a homebuilt box. The sub can LITERALLY shake your brains loose from anywhere in the hall. You can be sitting on the crapper and this sub will force the little guys out of you LOL. His speakers are Infinity, and he is using an Acoustic Edge sound card for Virtual 5.1. He is an administrator on a popular website bulletin board...here is a post he made.
"I'm thinking 2 pairs of Infinity Interlude IL40's ($1k for each pair). A matched center channel IL36 ($500) and Onkyo TX-DS787 reciver ($1k) to drive this setup. For subs 2 10" Infinity Perfect 10.1 (car subs about $250 for each cone) and a 1000W QSC PLX1602 amp ($800) to drive them.
Yeah it'll be expensive (about $5k), but I figure I should be able to rival a movie theatre for both volume and clarity of sound. I also won't have to upgrade any time soon after that purchase."
Yes, he's a freak, but he knows his stuff. =)
Anyways, this is just to say that my 4.1's are GREAT for me, but child's play to people with real cash. =)
