Logitech Z623 Review

By |

Regarding PC audio, Logitech is arguably one of the biggest brands on the planet. They offer everything from budget entry-level PC speakers to high-end surround sound systems for movies and gaming. Today, we’re focusing on the Logitech Z623 Speaker System with Subwoofer. This ultra-compact PC speaker system is an excellent choice for home offices, small gaming rooms, and apartments where you want to improve your PC audio.

Logitech Z623 Specs

Power output: 200W RMS (including 130W subwoofer)
Audio inputs: 2 x ⅛-inch AUX, RCA + ⅛-inch headphone output

Design and Features

If you’ve purchased any Logitech or PC speakers before, there isn’t anything different or unique in the Z623 design. The aesthetic is somewhat standard for a set of PC speakers. The Z623 is a 2.1 system with two 35W satellite speakers and a 130W subwoofer.  Both the satellites and subwoofer are constructed of premium plastic.

The subwoofer features a 7-inch driver in a large square enclosure. The grille sticks out a bit, which resembles something you might find in a car audio system rather than a PC speaker. This aesthetic gives the Z623 some street cred!

One design feature that many users may appreciate is the cable configuration. Most PC speakers connect to the subwoofer via the primary satellite speaker, which then links to the second satellite. The problem with this is you end up with a cable trailing at the rear of your desk or hanging down in a big arc behind the desk. With the Z623, both speakers connect to the subwoofer, which means the cables go over the back of your desk and out of the way. This might seem minor, but it can make a big difference if you like a tidy workspace.

Inputs and Controls

The Z623 offers two input points. On the primary (right) satellite speaker, there is a ⅛-inch AUX input; on the rear of the subwoofer, there is another ⅛-inch input and an RCA input. Having the two ⅛-inch AUX inputs is an appreciated convenience. The AUX input on the satellite speaker can be used for mobile devices, while the subwoofer on the subwoofer can connect your PC, gaming console, or other fixed devices. The RCA can be used for other fixed devices, too.

The only downside to the Z623 is no Bluetooth; however, you’ll be pleased to know there is a relatively cheap fix. The Logitech Bluetooth Audio Receiver costs under $40 and connects to your Z623 via ⅛-inch AUX. The ultra-compact receiver can sit on your subwoofer or beside the right satellite speaker to connect to your Z623 system.

The Z625 is available at around $20 more if you prefer using digital audio input. The Z625 comes with an optical input on the subwoofer. If you’re looking for a PC speaker system for gaming, then the Z625 might be the better option. If you’re considering whether to go with the Z623 or the Z625, the optical input is the only difference between the two systems. Everything else, including power output and performance, is identical.

Controlling the Z623 is very simple. There are two rotary knobs; one for volume and one for bass. Next to these controls is a power button for turning the speakers on and off.

The system offers a single output through a ⅛-inch headphone out located on the right speaker next to the AUX input.

Sound and Performance

The Logitech Z623 is a THX Certified speaker system. THX stands for “Tomlinson Holman’s eXperiment” which certifies a product has followed a strict set of standards for ultra-high-quality digital audio playback. The system delivers a staggering 200W RMS and 400W peak, which is mind-blowing given the size of the Z623.

The sound is well-balanced for gaming, movies, and listening to music. There is nothing overly exciting about the Z623 sound signature other than the speakers deliver a great sound. It’s by no means ‘audiophile quality’; however, at a $150 price point, the sound quality is better than you would expect.

One thing that is a little disappointing about the Z623 is the subwoofer. While it does produce some sub-bass, it’s not as powerful as expected. Still, for small rooms, the bass will be more than sufficient. If you’re using the Logitech Z623 in an apartment, it’s loud enough to annoy the neighbors. The bass is nice and punchy, making playing games and watching movies exciting.

The satellite speakers do an excellent job with the mids and treble. The sound is well-balanced and smooth, with no harshness or dominant frequencies standing out. The highs are nice and crisp, although somewhat back in the mix. The best overall depiction of the Logitech Z623 sound quality is ‘pleasant.’  These speakers aren’t going to win any awards for sound design, but at this price point, you definitely won’t be disappointed with the audio quality.

Logitech Z623 Conclusion

If you’re a Logitech fan, this purchase won’t disappoint you. The Z623 has thousands of 5-star reviews online, and you can see why. The system does what it says on the box and is built to last for many years.

If you’re looking for a PC speaker system for your home office, apartment, or other small space, then the Logitech Z623 is definitely worth considering. While the Z623 delivers a somewhat immersive audio experience, the system will get lost in bigger rooms. The system is great for proximity listening, but you might find it too directional to watch movies with friends or to fill a living area with sound.

If you’re a serious gamer looking for a big system, you might find the subwoofer on the Z623 slightly underwhelming. I recommend one of Logitech’s larger speakers for big sound and bass.

Another thing to keep in mind is the Logitech Z623 only has analog inputs. The Z625 offers a single optical input. However, neither model offers Bluetooth. If you don’t want to go with the Bluetooth receiver mentioned in this article, you must go with something like the Logitech Z537. The Z537 is slightly cheaper and has Bluetooth built-in, but is more than half as powerful as the Z623.
