Logitech Z623 Review

The Logitech Z623 is a powerful desktop speaker system. The 2.1 system (which means you get two speakers, or satellites, and a subwoofer) is THX-certified . The testing we put this through, however, showed that the system proved to be impressive for movies and gaming but much less so for music.

The Good: THX certified, powerful subwoofer

The Bad: Too boomy for music

Performance

It's hard not to compare the Z623 with other Logitech systems we've reviewed , and it doesn't always come out on top. Make no mistake: This is a pretty powerful system for a set of desktop speakers. Don't get this if you're going to be using it in a small, enclosed room. Unless you hate your roommate, this is not a system for dorm rooms and would just be a waste.

If you're a gamer, however, or a movie lover, the Z623 can be pretty impressive. The side-firing subwoofer thumped nicely during "The Day After Tomorrow" although it proved to be way too boomy during "Sunshine of the Spotless Mind" and needed to be nearly eliminated. This is a wired system, so you will be limited on how far apart you can place the satellites (although you can buy wire extensions if you so truly desire).

And the boomy subwoofer is wherein most of the problems reside for this system. Now, a subwoofer is supposed to boom, of course, and it's those booms that make your movie watching or RPGs that more exciting. But in some cases, and this is unfortunately true for the Z623, the boominess is just too distracting and distorting for many sounds.

Most of the music tested on the system was too boomy with the subwoofer on 50% and way too tinny when it was reduced. It was extremely difficult to find a pleasant medium, and all of the fiddling (often from song to song) was frustrating. Distortion was frequently detected when the speakers were past 30% of volume potential.

Design

It's a fairly attractive system, with matte-black satellites that are slightly squat. These are front-firing satellites, so they do not have the 360-degree sound that Logitech boasts in its Z323 system. While these speakers can certainly be cranked loud enough so that everyone in the room (and next house over) can hear them, there is naturally a marked difference between sitting in front of them and even slightly to the side.

Bottom Line

The Z623 is an option for gamers or movie buffs who want the power of a 5.1 system but not the price or added hardware. All other users need not apply.
