How do you "review" a product you havent used?
<Rant On>
Not for nothing, but... Really! I'm supposed to take a review seriously when it's clear that the "reviewer" not only has not used the product, but isn't even familiar with the product family? The Z600 and Z5500, the predecessors to the Z906 are, arguably, the best bang for the buck computer speakers of their respective generations. The bass is, actually, room shaking in most dorm room or home office settings. While hardly the last word in fidelity, they are plenty satisfying; playing loud and clear with minimal distortion (as long as you are judicious with the bass level). Though not satisfying for anything approaching "critical listening" of music, they are more than adequate for gaming, dorm room parties (or anytime the music just has to be loud with booming bass) and watching movies in full surround (Dolby digital and DTS) on the cheap.
In fact, AFAIK, Logitech is the only game in town still making 5.1 computer speakers. Oops, wait a minute, I seem to remember Corsair is challenging the position Logitech won by attrition from the likes of Creative and Cambridge. I have yet to hear the Corsair offering, but they generally offer products of higher than average quality and performance. Regardless, my point is not that I have heard the Z906, but that it is ludicrous, IMHO, to review a system you haven't heard; especially when you don't even have familiarity with the previous generations of the product family to lend your opinions credibility beyond that worthy of pure conjecture. Logitech has a history of improving each generation of this product, making the newest offering more than deserving of a listen before being disparaged based purely on the specs published. Especially when the provided specs are all but useless in the absence of a meaningful way to correlate said specs to sound quality.
