Logitech Z623 2.1 PC speaker system

Updated on March 21, 2015

Among the range of equipment that the Logitech Z623 can be used on include televisions, computers, audio equipment, DVD players and other audio sources with a 3.5mm or RCA audio output such as the PlayStation2, PlayStation 3, Xbox 360 or Wii (connected to your console via the supplied AV cable)

The powerful bass, clear highs and rich tones bring your music, movies and games to life. The powerful 2.1 system includes a two-satellite setup and a powerful subwoofer for full sound even in large rooms.

The device is delivered with speakers, subwoofer, 3.5mm audio input cable, speaker cable and a user manual.

Unpacking and connecting the device is very fast. The device feels and looks like it is made from very high quality material despite the fact that it is made from plastic. Granted, they may be not the best speakers but this is a matter of taste.

On my first try, I was pleasantly surprised by the clear highs, rich mids and powerful bass which one can regulate using a small wheel.

I personally set the bass control to half volume because that is totally sufficient. Compared to other models, I find that the Z623 does not sound so overloaded with bass. The bass on the new device is in my opinion does not boom so hard.

I have so far already used the speakers on almost everything (movies, music and games) and can barely see any downside. Even at full volume, there is no excessive boom, but this can vary depending on the type of music been played.

The only problem you will have with the speaker is piano music from the satellite speakers especially at low volumes. But I think that someone who want to hear piano music should keep away from 2.1 systems as they are not the best.

Whether classic rock or jazz, the sound is absolutely clean – no distortions. Video films give a cinema-like sound experience and you will be easily lost in the action. If the small speakers are placed in the proper spots to the left and right of the source, the sound effects are unbelievably good given their small size.

Further tests confirmed that the price-performance ratio is very good. This system is worth every dollar and in my books it is not a bad deal at all.

But one thing you have to keep in mind is that the sound quality of any device is ultimately dependent upon the source. A cheap Mp3 player or incorrectly set equalizer settings will nullify any good qualities of the equipment and ruin the sound experience.

Uncompressed (ideally- original) audio CDs or original DVD are best suited for the speakers. Also, a cheaper player often brings with it a loss of quality. I recommend here original CDs or DVDs.

I use it on the PC as compensation for the X240 system from Logitech which also was good but had a hum that was becoming unbearable. It took a long time to decide on the Logitech Z623 because I thought that the peripheral speakers would be huge.

Compared with the Z523 which is uglier and has a modular form and cheap looking piano lacquer design that is incompatible with many desks, the Logitech Z623 is a godsend.

However, it was difficult to make out what the correct dimensions of the Z623 are. When you check online, it is very hard to get the right dimensions. Some gave the width of the satellite speaker as 14.2 cm which is not correct. Compared with 8.6cm for the Z523, that would make it appear monstrous.

So here are the correct dimensions of the Logitech Z623 - Satellite: 20.5 x 11.2 x 12.2 cm Subwoofer: 28.5 x 30.0 x 23 5 cm.

With their tapered shape, the speakers appear less bulky. The design is a matter of taste. I like it much better that the Z523 system.

Now for the sound: I listen to a lot of jazz, RnB and Funk. I also have several Gbs of electro and classical music on the hard disk. I am currently using the on-board Realtek sound card of my new B3 Socket 1155 quilted motherboards and I am absolutely thrilled.

I have set the equalizer to “full power” and then raised the middle of the profile. This is the best sound for me. The subwoofer is set at about ¼. When I listen to classic music, I turn the knob down a bit but for hip hop and movies, I turn it up.

Though there have been some rather harsh criticisms of the Logitech Z623, I do not seem to understand what their beef is with the system. They appear to use the Z623 as a spare 5.1 in the living room and then compare that with a $1000 surround system.

I should emphasise here that this system is to be used more on the PC. When put in the right place, the satellite has a sound that is hard to beat. In my view, what one needs to do is properly regulate the sound of the satellite in order to get the best result.


I would highly recommend these speakers as they provide a rich bass sound for relatively little money. Hopefully, this review has helped you in making a decision on whether or not to purchase these speakers.
