At a time when the iPod speaker dock is so ubiquitous, it’s getting hard to find manufacturers dedicated to designing high-quality audio systems for PC use. Therefore, it's reinvigorating to see an industry bigwig such as Logitech step up to the play and craft one of the best performing 2.1 channel PC audio systems.

Just above the 100-dollar mark, the Z623 doesn’t necessarily come across as a bargain. But it makes up for its hefty price with an outstanding audio output and punching power. As much as movie buffs are lovestruck by the THX certification, the speaker is equally suited for playing music. The thunderous subwoofer can be cracked up for an outdoor party and dialed down for a more refined output.

So, what else does the Logitech Z623 offer?

A Logitech Z623 Review

Size and Design

Being an audio system designed for gaming and watching movies, you would expect the Z623 to have the looks of most speakers in its genre. A typical gaming speaker has extra design elements, curves, and rough edges. Interestingly, the Z623 has none of those traits. It looks more of a powerhouse that you would find in a music studio.

The stereo speakers have dimensions of 7.8” x 5.6” x 5.4” and positioned upright for better desktop usage. On the front panel of the system’s right speaker are three knobs – for adjusting the volume, power, and bass – that are conveniently positioned below the 2.5-inch driver. The positioning of the bass knob is unique since most similar systems have them placed on the rear end of the sub.

The right panel houses a headphone jack an Aux input. A large cable for connecting the speaker to the subwoofer extends from the back.The left speaker is linked to the sub by an RCA connection.

The cables are non-removable, and this presents the first shortcoming to an otherwise perfect design. In most music systems, the cables are the normally the first item to get damaged. If this happens on the Z623, you will be required to buy a whole new set or pay for an unnecessary repair.

The sub is quite huge, measuring 11.9” x 11.1” x 10.4”. In addition to the said connections on the system’s rear panel, the sub also hosts a 3.5mm auxiliary input as well as a stereo RCA input for connecting to the PC.

The Z623 doesn’t come with a remote control despite being an absolute powerhouse. So if you use this beast for a party or video games, you’ll certainly miss the convenience of adjusting the bass and volume remotely.

Sound Output

There’s no doubt that the Z623 is an outstanding performer. The twin satellite speakers deliver crystal clear high notes with incredibly detailed midranges, while the sub cranks out a deep bass that’s powerful enough to rattle everything in your room.

The wattage of this system is simply exceptional. Each of the twin speakers pumps out 35 watts of distortion-free output, while the sub puts out 130 watts of low-frequency sound. With a total wattage of 200, the Z623 will certainly electrify your party with its incredible sound.

Even better, is that you can set the system into “loud” mode by adjusting the bass knob to maximum. In this mode, the mids will still retain their impeccable detail, and the bass response will hit twice as hard.

And what about the THX certification? What does it mean for the 2.1 system’s movie performance?

You must understand that it’s almost impossible to replicate the exact sound of a THX theatre with just one subwoofer and two satellites. In the case of the Z623, Logitech elusively interpreted the THX certification to mean that the system meets high performance, reliability, and quality standards.

That said, the THX hype is very real. The manufacturers have utilized THX standards to modify the speaker's output, much to the delight of movie and game enthusiasts. Watching a movie on the Z623 is the closest you can get to the immersive experience of multi-channel theatre systems. Gunshots and shattering sound more real and conversations are clearer than what you would get with an ordinary 2.1 audio system.
