PC audio system considered as one of the peripherals in PC Builders community even in 2021 where most audiophiles are moving towards headset and wireless headsets. PC speaker manufacturers like Audioengine, Harmon/Kardon, Klipsch and KEF considered as a few available premium brands. However, not all users able to buy those brands. The best options available for most consumers under a tight budget are to opt for mid-end audio brands like EDIFIER, Creative, Logitech and BOSE. The remaining budget consumer will move towards low-end speaker manufacturer such as from SonicGear and Vinnfier.

Figure 1: Logitech Z623 Review – Introduction.

Nuff with the long introduction, I’ve recently purchased a unit of Logitech Z623 during Shopee’s 4/4 sales. I am not a logitech-fanboy as I don’t really have a good experience with the brand. However, while surfing to through Shopee, I came across with this model and proceeds to do a standard online research. Also, there is a YouTuber who giving negative review on this model and the components used for this model can be viewed here. Looking at the criticism, I decided to buy a unit for myself.

Upon unboxing the speaker unit, only one standard accessory, a 3.5mm audio male-to-male jack were given. Apart from the cable, you will get two satellite units of Logitech Z623 and a subwoofer.

The satellite speaker powered by a 3-inch driver rated 35W each. The right satellite speaker gives you an access to power on the system, controlling the volume and bass level. There is a THX logo on each satellite speaker. However, if you are looking for a speaker system with a dedicated tweeter, ignore the Z623.

Powering the sub up is a 7-inch bass driver rated at 130W. The woofer driver is protected by a grill and if you happen to place the subwoofer down your desktop, be prepared to prepare a suitable tool to clean the driver up from dust. The subwoofer feels light and doesn’t seems weight around 7kgs. With dimensions up to 284mm x 305mm x 266mm, the subwoofer is best placed below your desktop or TV rack.

Looking at the rear of the subwoofer, you get a pair of RCA port, a 3.5mm audio jack, a VGA port for right satellite speaker and an AUX port. From my view, the location of the I/Os are at the right place.

Generally speaking, THX-certified audio systems were well tuned to produce an optimum audio quality. Being an audiophile, I don’t really like to tweak the onboard EQs and kept everything as default. This somehow will allow the speaker unit to produce a better audio as it designed to be. Since Z623 only comes with a dedicated bass controller, the bass level can be controlled. Similar to Klipsch Pro Media 2.1, Logitech recommends to put the bass level at 50% for optimum performance. When it comes to music, I truly enjoy my music session since I always listen to 320Kbps at 16bit mp3 file. The Z623 can’t really give you a true home-theatre feel since your living room layout plays a vital role here. BUT… there is a big but there, the Z623 do produce a balanced audio quality while watching movies through my office computer. Next, the Z623 is highly suitable for hardcore gamers since the model scores full mark here. The bass output is simply superb along with how well the satellite drivers channels the audio to the ear while gaming.

Figure 6: Logitech Z623 Review – Conclusion.

To conclude the review, the Logitech Z623 certainly a good THX-certified system, well from my point of view. Being an audiophile, I find that the system isn’t that bad as claimed by others. I don’t say it outperforms my Harmon/Kardon Soundsticks 4, it performs as how a good THX-certified speaker should be. Comparing with EDIFIER’s M3600D, the Logitech Z623 is slightly cheap and worth to be considered.
