Hey guys! Just looking for a recommendation here, looking for some new speakers for my Macbook Pro. Requirements: Must support 5.1 (or better) surround sound (over optical.) Less than or around $2000 (Australian.) I'm looking for good clarity at high volumes. At the moment I've got the Logitech Z-5500 set, which are great, but the satellite speaker themselves just aren't really big enough to deal out clear audio at high volumes.
