I recently spent a day shopping for a subwoofer-satellite speakers system for my new iMac. After going to all the big-box stores (Best Buy, Circuit City, CompUsa) in my area, I was pretty disappointed with the performance of available choices. After spending over two grand on a 20 inch iMac G5, I didn't want to spoil the new mac experience with crappy speakers. Things turned around when I went in to Cambridge Soundworks where they have a kind of mix and match system based on the BassCube 821. The 821 is powered sub with an amplifier built in to power the satellite speakers, which is functionally pretty much the same as other computer speakers. The difference is that you can either get it as part of a sub-sat package or just get the sub and match it with just about any pair of speakers you want. CSW offers a range of satellites, from little cubes to larger two-way bookshelf speakers .Of course, you don't have to get everything from CSW. What I ended up doing was buying the 821 at CSW and a pair of Mirage Omnisat Micros from Tweeter Etc. The Omnisats are awesome sounding little speakers with extremely wide dispersion. They're also pretty cool looking. If there's a down side, its that this set-up ends being more expensive than most of the computer speaker packages out there. The BassCube 821 costs $200 and the Omnisat Micros cost $359 a pair at Tweeter. Of course, you can use much less expensive sats, but for me, this combo was worth the money. Any way, I just felt like sharing this info with all of you. I'm really happy with the sound I get from this combo and I also like the stark contrast between the iMacs brilliant white and the stark black Omnisats.
