The Logitech Z623 400-Watt home speaker system is a 2.1 speaker system formed by left, right satellite speakers, and a subwoofer. The speakers are active, meaning quick and easy setup by plugging them directly into the source.
The subwoofer’s dimensions are 11.2 x 12.0 x 10.5 inches, and its weight is 15.4 pounds. The right and left satellites have 7.7 x 4.6 x 5.0 inches in size. Each of them weighs 2.2 pounds. The speaker system comes with 6-feet cables to satellites. If they are short for the desired placement, it’s possible to replace them with longer cords.
The units have more than enough peak power to match any room and smaller gatherings outside. The speakers meet the THX (Tomlinson Holman’s Experiment) Sound certificate that is a standard for digital sound playback. So, the sound quality is really great, even when the speakers are not placed properly. However, consider the Logitech Z623 manual if it’s fundamentally important to place them as the manufacturer advises.
The general sound is rich and distortion-free. The mid-range frequencies are vibrant and expressive. The bass will be smoother and fuller if the bass knob will be turned up approximately between 1 and 2 o’clock.
The Logitech — Z623 2.1 speaker system has two 3.5mm jacks, an auxiliary port, and one RCA input to hook up to 3 devices simultaneously (e.g. a gaming console, a TV, and a laptop). This way, there is no need to disconnect the sources of the signal while toggling between them.
A black speaker with a matte finish is made of ABS plastic and devised being placed at an angle. It is narrower at the top and wider at the bottom for better stability. Each speaker has a single 7-inch up-firing tweeter sealed with rubber and covered with a protective metal grill. Those who prefer to enjoy open drivers can remove the grill (it takes some amount of force, to be honest). The sub’s port is 2.5 inches across, having the built-in amp boards and power supply.
The drivers are magnetically shielded, having an aluminum phase plug. This construction contributes to a powerful acoustic energy, dissipating heat. All this stuff makes the Logitech Z623 system more efficient. There are rubber pads at the bottom of the speakers to reduce vibrations during the operation.
The users will find all the controls on the right speaker. They serve to power the system, adjust volume, connect headphones via a dedicated jack, and audio equipment via AUX port. This speaker houses the power, being connected to the sub via a VGA-style cable. A phono plug connects the sub to the right speaker.
Summarizing the Logitech Z623 review, I’d like to note that this system is perfectly suitable for listening to music, watching videos, and playing games. This application caters even to picky listeners. However, the speakers do not produce the immersive surround sound to reveal all the dialogs, background effects, and audio tracks’ nuances while watching movies on the TV.
