Why Buy The Logitech Z623

The Logitech Z623 is designed for gaming, packed with loads of power and quite easily our top pick among all gaming speakers. Costing just a little over $100, this 2.1 speaker is so much more than just an average satellite and subwoofer combination. If you don’t mind the high 200-watt power requirement, the Z623 will serve you well for years to come.


Why is it that 2.1 speaker systems tend to falter the moment you cross the 60% volume mark? It is because they aren’t suitably powered. The Logitech Z623 however, works on 200 watts of input power to ensure you never compromise on loudness and clarity. These speakers are THX certified with a deep resounding bass that rattles your bones with precision. All you have to do is plug in an AUX or your PC line IN, and you are ready to go.

THX certification is stringent, and not all speakers can achieve the high-performance standards to get one. But when a speaker does receive THX certification, it means the speakers are capable of doing much more than just gaming. With ample power, thunderous bass and performance at par with the best, these speakers bring out realism in games. Music, movies, and recordings all seem so much more studio-quality with power that just does not stop. Keep increasing the volume or the bass as you need to for an immersive audio.

The Logitech Z623 uses quick-access RCA and 3.5mm input that can take a total of three audio inputs. It also has a headphone jack if you ever need it. By the way, the subwoofer is rated at 130 watts, so go easy on the controls unless you want to shatter the peace in your neighborhood playing Battlefield.

Logitech Z623 400 Watt Home Speaker System, 2.1 Speaker System
  • THX-certified 2.1 speaker system brings your music, movies and games to life in immersive studio-quality audio
  • 400Watts of Peak/200Watts (RMS) gives you the power to listen as loud as you want to while the on-speaker controls lets you easily dial the volume and bass up or down
  • RCA and 3.5mm inputs make it easy to plug in up to three audio devices - your computer, iPod, game console, DVD player and more

Our Review

What is it that you look for in a gaming speaker? For us, it is the near realistic reproduction of footsteps, vehicles approaching and ricochets. Sound effects are more vital to immersing in a game than the background score. Speakers not designed for gaming, or underpowered speakers both tend to provide a good overall feel but they do not give you that extra peripheral sensory playing games. The Logitech Z623 manages to produce a holistic feeling, somehow merging the background score with sound effects for an immersive experience.

Unboxing this speaker was a bit of a surprise. Gaming speakers usually tend to have more curves, rough edges, and design elements. The Z623 though has none of that. It does not scream gaming speakers though the subwoofer looks a lot like a powerful studio-quality product. By the way, the sub is pretty heavy so you might want to keep it on a sturdy wooden base or the floor. The cables are long enough, and that is a good thing because these speakers pack a lot of power, so you want to maintain proper separation between them.

The first time we turned the speakers on was without connecting to a PC. Instead, we tested it out with music since these are THX certified speakers. Using a FiiO player, we randomly streamed all kinds of tracks for over a couple of hours. Yes, such speakers do have a break in period, and while the Logitech Z623 sounded great during the break in period, after a couple of days it opened up, and the bass had more of an earthy feel to it than before.

During our break-in period, we also connected the speaker to our PC and gave it a whirl with a few choice titles. To test speakers, we love playing Battlefield One because spatial awareness is so crucial to dominating the online scene. Coin tosses were crystal clear including the direction. Because these speakers are great at meeting specific frequencies and directing them, you get a sense of direction from each sound. Please note, your sound card should be able to offer Sonar or some technology that plays directional sound for this to work. But, if you do have directional functionality, these speakers sound awesome.

Let’s talk about the bass of the Z623. On the first day of unboxing the speakers, when we were testing for manufacturing defects, we cranked up the volume to somewhere around three-quarters of the way. Almost immediately, our coding team came banging on our side of the office demanding to see what was causing all the ruckus. These babies are loud and shameless!

After the break in period, the volume had no effect on the sound quality. Go higher than three-quarter, and you still get the same quality and clarity every single time. Increase the bass, fiddle with the volume, nothing changes. Yes, this Logitech Speaker truly is an amazing piece of machinery designed to take your gaming experience to the next level. By the way, it lets you use a headphone directly from the speakers without needing to plug it into your PC and is more than capable of driving robust cans.


  • 200 Watt is way more than any 2.1 surround speaker system will ever need.
  • The bass on this Logitech speaker is not just strong and capable but also clear.
  • THX certification does give the speakers higher trust value regarding longevity and durability.
  • Logitech is a brand name that you can trust.
  • 5mm inputs for a total of three audio devices including your computer.
  • Headphone out allows you to connect any pair of cans without worrying about the power delivery or performance.


  • The subwoofer is heavier than any 7.1 system subwoofer. It was probably designed for a larger speaker system.
  • The overall style does not feel gaming-centric at all.


Logitech is a brand name you can respect regardless of the gaming peripheral. There are only a few other brands that garner our respect like Logitech does. Without a doubt, we can say that the Logitech Z623 lives up to this reputation. It isn’t just marketed as a beast it is a beast!

Small and yet powerful speakers, a large 130 Watt subwoofer with precision 2.1 surround sound effect ensures that the Z623 behaves less like a dual speaker setup and more like a 3D 7.1 speaker setup. Gaming on these babies is just incredible and playing music or watching a movie is as good as the big screen. Not only are the highs distortion free but the mids and lows are surprisingly clear too. Together with a great bass, this 2.1 speaker is easily the most adept dual speaker setup we have ever come across.

The only complaint we can have is that these speakers don’t look like PC gaming components at all, what with their ubiquitous styling.
