Any 5.1 amp/reciever that can power 5 speakers will do surround. Assuming it has 5.1 inputs.
The ' .1 ' is simply a LFE or a subwoofer line that is crossed over.
Honestly, I prefer the natural rolloff of the Insignia speakers over all other Pc speakr subwoofers. So if your delema is loosing a subwoofer, then, honestly, is no loss 8)
My Klipsch Ultra 5.1 sub had dual 8" drivers, and the where good down to 30hz, and had some output at 25hz. The problem was the bass was muddy and the drivers bottomed out easyly at high volumes.
Other subs from Creative, Cambridge, Logitech sound just as bad.
