The Inspire 6700s are the first 6.1 capable PC speaker system to be available in the market. Touted as the ‘perfect companion’ for Creative’s own Audigy 2 soundcard, the most obvious addition is the rear centre channel that takes full advantage of Audigy 2 features and grants you some Dolby Digital® Surround EX support, however what makes this more interesting is CMSS (Creative Multi-Speaker System) that is said to up-mix surround to 6.1 channels when used with a 5.1 sound card. I suppose one of the most common questions among the people reading this is going to be, what kind of improvement resulted from the 5.1 to 6.1 jump? We tested with both 5.1 and 6.1 cards to give you a fair answer. Read on and find out.
