- Bottom Line
Logitech’s THX-certified, 2.1-channel Speaker System Z623 pumps out powerful, sweet-sounding PC audio at a nice price.
In the age of the ubiquitous iPod speaker dock, it seems few manufacturers are still making quality speaker systems designed for computers. So it's refreshing (and a little surprising) to see one of the leaders of the pack, Logitech, step up with one of the best-sounding 2.1-channel PC speaker sets we've tested in a while. At $149.99 (direct), the Logitech Speaker System Z623 doesn't quite qualify as a steal, but it delivers excellent audio performance and surprising power for its price range. The THX certification will attract some movie buffs (more on that later), but the Z623 is equally appropriate for music, with a thunderous subwoofer that can be dialed up for the party's sake, or scaled back for more refined settings. Logitech gets the details right with the Z623, and earns our Editors' Choice with this well-executed 2.1 system.
Design
Unlike, say, the Harman Kardon SoundSticks II ($169.99, ) another excellent 2.1-channel set—the Logitech Speaker System Z623 will take up a significant amount of space. The 7.8 by 5.6 by 5.4-inch stereo speakers (HWD), which are angled upward for proper desktop listening, are shorter and wider than most desktop speakers. The right speaker's front panel houses three knobs—for Power, Volume, and Bass level—under the 2.5-inch driver. Two 3.5mm connections—an auxiliary input and a headphone jack—sit on the right panel of the speaker, and a large, hard-wired cable that connects to the subwoofer protrudes from the back. The left speaker has a thinner hardwired cable that connects to the sub via a single RCA-type connection.
The problem with these non-removable cables is obvious: cables are usually the first thing to go bad in a system, and when they go, no matter how well the system works otherwise, you'll need to replace the whole set or pay for an involved repair. It's a bummer, but since the system is $150 (and not $300) and with good care it should last you at least a few years, we can't be too hard on Logitech for this decision.
The subwoofer is huge, in every sense of the word. The behemoth measures 11.9 by 11.1 by 10.4 inches (HWD), and its output could rattle the paint off your walls. Luckily the bass knob, conveniently placed on the right speaker and not on the back of the sub like systems from some manufacturers (ahem, Harman Kardon), can dial the sub's level back to musical levels. The knob has a stop at the halfway point, but I'm not quite sure I'd consider that spot a flat setting—dialing it back a bit more will probably get you closer to flat response. Aside from the aforementioned connections on the subwoofer's rear panel, the sub houses a stereo RCA input and a 3.5mm primary input for standard PC connections.
The system lacks a remote control, which doesn't really matter if you're only using it at your computer—though that wouldn't do the Z623 justice. Speakers this powerful are meant, in my opinion, to power a party or accompany a gaming system or an iMac used for watching videos, so the exclusion of a remote is a bit disappointing.
Performance
The Z623, simply put, sounds awesome. Film scores from Bernard Hermann sound crisp and foreboding, with deep lows from the strings beautifully represented by the sub and the satellite drivers. Music with deeper bass, like the Knife's 'Silent Shout,' sounds closer to what the musicians had in mind—powerful-but-well-defined low end—than most 2.1 systems under $200 can deliver. When you blast the system and turn the bass all the way up, you won't hear any distortion—but, again, you'll want to secure fragile items nearby. With each satellite delivering 35 watts and the sub pumping out 130, the Z623 is definitely loud enough for your next party. At moderate and even low levels, it conveys music and dialogue beautifully. Turning the bass knob to maximum (or close to it) with the volume way down accomplishes what 'loud' buttons on older stereo receivers used to—you still hear the bass even when the system is operating at quiet levels.
Let's touch briefly on the Z623's THX certification. Most people remember THX audio because of George Lucas and the initiative to certify movie theaters so that if you see a movie in a THX-certified theater, it meant that the audio was mixed according to certain specifications and you could rest assured you were hearing a close approximation of what the director wanted you to hear. It's a great idea, and it quickly spread out of the movie theater to home theater systems, and now the THX certification is being given to non-surround sound systems like this one.
How can THX ensure that if you watch a movie on a 2.1 system that the sound will be as awesome as it would be in a THX theater with a lot more than just two satellites and a subwoofer? That part's impossible. The certification, in this case, is vaguely described by Logitech to mean that the Z623 has 'met strict performance standards and will deliver quality you can count on.' Does that mean anything? My two cents: it can't hurt for the minds and ears at THX to help Logitech tweak and improve a speaker's performance, even if the system can't possibly be held to the same standards as multi-channel home and movie theater systems. So, it's not just a stamp or hype, but it doesn't mean the same thing it means when you go see a movie in a THX theater.

The biggest differences between the SoundSticks II and the Z623, aside from their completely different visual designs, are overall power and high frequency response. The Z623 packs more power and more bass, while the SoundSticks II have the high frequency response that I tend to prefer. The high frequency response on the SoundSticks II is bit crisper than you get with the Z623, but that's not to say the Logitech system is muffled. Its definition in the high frequencies is beyond adequate, but head-to-head, the Harmon Kardon system is the brighter of the two. That said, without the A-B comparison, it's easy to forget that the Z623 lacks that extra bit of high-range shine that helps balance out a powerful sub. The THX certification process—whatever it happens to mean in this case—produces a system that is a joy to listen to and can be sculpted to taste, whether you're a bass junkie or a flat response fan.
