Logitech Z906: The First New 5.1-channel PC Speaker System in Years
Finally, a replacement for the aging Z-5500
UPDATE: Logitech has informed us that they provided us with incorrect pricing information for this story: The Z906 will sell for $399, not $349.99 as Logitech originally stated. This is probably just a sloppy mistake--the bill of materials for a 5.1-channel system must be high, even for the quantities that Logitech buys--but cynics will suspect that the manufacturer saw the public's largely positive response and decided to rake in a few more bucks. For the record, we think Logitech just screwed up.
We’ve waited so long for Logitech to replace its 5.1-channel Z-5500 speaker system that we finally quit asking the company about it. The Z-5500 ruled our best-of-the-best list from 2004 to 2005 before M-Audio’s Studiophile LX4 knocked it off its perch. We put it back when M-Audio discontinued the LX4 several years later, and it’s been there ever since.
Logitech typically briefs us in advance about major new products, but we didn’t hear anything about the all-new Z906 until an email arrived yesterday; Logitech tells us we should be getting a review unit soon. We're definitely looking forward to it.

How do you spell "awkward?" Logitech's original fact sheet incorrectly claimed the Z906 would sell for $349.99. The actual price is $399.
In the meantime, here’s what we know about the system:
As with the Z-5500, the Z906 will be THX-certified and outfitted with an onboard surround-sound DAC capable of decoding Dolby Digital and DTS-encoded soundtracks transported over digital optical or coaxial cables (the system will also have stereo RCA and stereo 3.5-inch inputs). Although Logitech mentions a Blu-ray player as a possible source (the system has six inputs), the Z906 is not outfitted with HDMI pass-through and apparently cannot decode Dolby TrueHD or DTS-HD Master Audio bit streams. The system is well equipped, however, for gaming consoles such as the Xbox 360 and PlayStation 3.
The amp will deliver a total of 500 watts RMS (67 watts to each satellite and 165 watts to the ported, side-firing sub). As did the Z-5500, the Z906 will have a central control console and an infrared remote control. The Z906 will sell for $349.99 $399.99 when it ships later this month.
