When it comes to gaming and watching movies, the THX-certified Logitech Z623 speaker system performs admirably, though critics don't quite agree on its prowess at handling high-fidelity music. While the Z623's 200 watts of power (total) and thunderous bass can be cranked to room-shaking volumes, some critics are less than enthusiastic about the sound quality of music in the midrange. Others give it high marks across the board.
Shake the roof off. Most won't feel the need to dial the Logitech Z623 up to room-shaking volumes, but it's good to know that this 2.1 speaker system packs the extra punch when needed. Reviewers agree that this system is great for gaming and film watching, and they appreciate its overall power. The Z623 is a THX Certified Multimedia computer speaker system, meaning it is designed to deliver accurate audio when playing computer games or enjoying multimedia. PCMag.com's Tim Gideon says the Z623 "sounds awesome" and awards these speakers the Best of the Year Award for 2010.
Opinions vary, however, about music. MaximumPC's Michael Brown says the Logitech Z623's speakers "barely pass muster." His complaints focus on the midrange for music listening. "The satellites overdrive mid-range frequencies, rendering broad swaths of both vocals and instruments unpleasantly harsh at higher volumes," he says. Owner reviews at Amazon.com are generally favorable, citing great sound for the price from these speakers.
Accessible connections pair and a sturdy build. Connecting a wide range of devices to the Z623 isn't a problem, thanks to RCA and 1/8-inch stereo inputs on the subwoofer cabinet as well as a second stereo 1/8-inch input jack on the right-hand speaker. Volume, bass and power knobs are also located on the right speaker, alongside a headphone jack.
Critics give these speakers a thumbs-up for their solid build, but they note that the bulky subwoofer takes up a lot of room. "The subwoofer is kind of a beast: 12" wide, 11" tall, and 9" deep doesn't sound so big -- until you try putting it under your desk," says TechCrunch.com editor Devin Coldewey. Additionally, he reports crackling sounds when adjusting the volume and connection issues with the headphone port.
Power without the wow factor. The Logitech Z623 excels at providing extra volume when the occasion calls for it, and it's a good pick for gaming and movie watching. That said, it doesn't deliver as clearly for listening to music, and it's not as widely praised as the similarly priced and far more unusual-looking Harman Kardon SoundSticks III (Est. $150) . Otherwise, it gets the job done and outperforms many cheaper computer speakers at a still reasonable price.
Excellent power output and audio performance earn the Logitech Z623 PCMag.com's Best of the Year 2010 Award and editor Tom Gideon's strong recommendation. "The Z623, simply put, sounds awesome," he says about this THX certified speaker system, adding that it also has the low end power to rattle the house when cranked up.

MaximumPC's Michael Brown is less enthusiastic about the Logitech Z623, saying it "barely passes muster" and giving it a 7 out of 10 rating. While he says the speakers perform well enough for movies and gaming, the midrange frequencies are unpleasantly overdriven when listening to high-definition audio files.

The Logitech Z623 earns a 4.5 out of 5 rating with more than 760 reviews from Amazon.com customers. Users say these speakers are great for both music and gaming purposes, and they say the power you get is well worth the price. Short hard-wired speaker cables and the unit's overall bulk are niggles mentioned by owners. A small percentage of users report speakers that are defective or that failed prematurely.
