The quality Logitech provide is incomparable. Personally, I have used numerous products from Logitech and all of them were pleasing.

There are very few speaker systems having the THX certification and Logitech Z623 is one of them. In fact, in the whole sound system series from Logitech, they only have two (2) speaker systems that have the THX certification. It has been designed mostly for gamers and users who are more concerned about the quality of the audio. The sound quality is mind-blowing at this price range. The subwoofer is heavy enough to lift but compact at the same time. The front side of the speaker is protected by a metal grill to protect the cone from any external incidents. Both of the satellite front portions are also protected by the same type of grills. On the rear side, it got the necessary power and audio ports to get it connected to the source and supply as well.

What is THX Certification?

It was called after Tomlinson Holman, with the "X" representing crossover or experimentation, and it was also a nod to Lucas' debut picture, "THX 1138." It is critical to understand that THX is not a recording technique, but rather a quality assurance method.

A THX-certified amplifier, receiver, or speakers, for example, will reproduce sound at reference quality for a certain room size. So, provided the components are properly configured, a THX-certified system will reproduce sound exactly as it was heard in the mixing studio.

Satellites contain a 2.5" full-range driver that looks quite great after the grill is removed.

It can perform well in with any audio content such as films, games, or audio with its 200 Watt RMS/400 Watt Peak power.

The bass response is so heavy. I’ve tested this speaker in a few situations to justify the real sound quality and in all tests, it passed successfully. It can deliver the low-frequency bass so well without distorting too much; in fact, you won’t be able to notice the little amount of loss there. The punchy bass gets delivered as it should be. The continuous low-frequency bass also can get generated in an effective way. In 50-60% master volume the bass can be felt from all other rooms of the house. Also, the neighbors living upstairs or downstairs can feel the bass vibrating a bit.

The sound system has two (2) control knobs, one for the bass and the other one for master volume control.

The music quality from more or less all genres sounds crispy and clear enough to enjoy.


  • Powerful heavy bass delivery maintaining THX standard
  • Crispy and clear sound in all types of content (mostly in games and movies)
  • User-friendly controls


  • Sounds (mainly bass) get distorted when volume increased over 70%
  • A bit heavy to lift

System requirements: Logitech Z623 will work with any device which has a 3.5mm audio port such as Television, Computer, Smartphone, Tablet, Music player, DVD player, Blu-ray™ player, PlayStation®, Xbox®, Wii™, and so on.

The ultimate question is “Should you buy it or not?”

The answer is Yes, in one word, in this price range this is the best choice of all. From all the aspects of a sound system, it fulfills all the requirements to be one of the greatest speakers of all time.
