Logitech Z-680 THX 5.1 Speakers Introduction

PC-Audio has always been flirting with challenging or, dare I say it, replacing traditional dedicated audio products. Most attempts have been good but nothing worth making you look at your hi-fi like a red-headed stepchild asking what has it done for you lately. Well, with modern games taking more and more advantage of people who do have outrageous multi-channel audio setups on their gaming setups coupled with ever growing numbers of people watching DVD's on their PC's or even who have media PCs merged with their home entertainment systems the bar is rising fast. The games, movies, and complimentary hardware such as multi-channel sound cards like the ones coming out from Creative, Hercules, and m-Audio, you have more choices for your sound delivery hardware as well as sophisticated support for DTS and SRS. The quality of speakers designed for your PC are now rivaling traditional home theatre speakers... the lines are getting really blurry. Let's take a look at a major contender.. the Logitech Z-680's.

Logitech has been making some serious bounds in audio over the last two years or so. I have some Z-340 2.1 speakers. I bought them because for the sound quality/price ratio was the best I could find. I have been very pleased with the performance of them especially since I picked them up at a national electronics chain for $40. The base from the subwoofer was full and the tiny satellites had surprisingly nice quality of sound as well for a budget set. But as good as the Logitech line has been, there has always been one name out there that has taunted them... Klipsch. It is strictly just my opinion but I believe that the Z-680 is a direct response to Klipsch's claim on the top of the PC audio mountain. Klipsch have always been outrageously priced in my opinion (even though I am definitely not going on record that they aren't amazing speakers). But lo, and behold now with some competition from the likes of Logitech, Klipsch's prices have seemed to come down to... wow... exactly the price of the Z680's. Competition is the champion of the geek, better products at lower prices. Don't get me wrong, $400 (MSRP - but at the time of writing this, I was finding them at reputable online dealers for $275) is serious money to pay for a set of speakers, but a year ago, you could have spent $100 more. I'm just trying to put the whole price thing in perspective while you're eyes are bugging out at the price tag.

That's right, 1000 Watts of peak power from PC speakers... where not talking your traditional set of speakers you used to have on each side of your monitor that you used to brag about because it had "bass boost" or something or other. What really sets speakers like these above your moderately nice garden variety speakers or even your nicer 5.1 sets is the hardware decoder module enabling Surround Sound and THX quality.
