Features and Performance

The Logitech Z623 features 200W of RMS and 400W of peak power. The Z523 system has 40W of RMS and 80W of peak power that is enough only for a home office or a small living room, for instance.

The opportunity to project sound across the board, deep hefty bass, and distortion-free sound is common for both systems. Nevertheless, the Z623 has the THX certificate to ensure digital sound playback’s quality. Unlike many other speakers, the Z523 and the Z623 feature bass volume control that allows balancing lows with other frequencies and trebles. However, the treble’s adjustment would be a great addition. Some mud is audible at extremely high volume levels produced by the Logitech Z523, but it is typical for entry-level speakers.

Setup

The Logitech Z623 vs Z523 check has revealed an equally straightforward setup that takes a couple of minutes. The subs are hooked up to the right speakers through the VGA inputs. The RCA cables connect the subs and the left speakers. The aux input is necessary to connect a laptop or any other desktop device to the system. Smartphones and tablets are hooked up through the headphone jack on the right speakers.

Both models can be connected with up to three sources (game console, PC, and TV, for example). However, the lack of input selection makes it impossible to play several devices at the same time.

Design

Both systems have a curved shape and upward angled tweeters to direct sound right to the listener that sits at the desk. The tweeters have removable grilles to protect the internals from clogging. The visual inspection of the Z523 vs Z623 has displayed the Z523’s more durable construction, as it is made of plastic and MDF, while the Z623 is completely plastic. The Z523 sub has four feet that protect its bottom from scratches.

The Z623 is 11.2 inches high, 12 inches wide, and 10.5 inches deep. Its weight is 15.4 pounds. The satellite is 7.7 x 4.6 x 5 inches each. The right speaker is a bit heavier because of controls: 2.2 versus the left speaker’s 2.1 pounds.

The Z523 sub’s dimensions are 10 x 9 x 9.5 inches, and its weight is 4.2 pounds. The unit is fitted with a 4-inch front and 6.5-inch side drivers. The satellite’s size is 11.6 x 3.4 x 5.2 inches, and they have two 2-inch drivers.

Both models’ controls are located on the right satellite speakers to adjust volume, bass, and to hook up the headphones.
