Logitech Z623 400W Home Speaker System, 2.1 Speaker System

The Logitech Z623 400W Home Speaker System is designed for gaming, packed with loads of power and quite easily our top pick among all gaming speakers in its price range. 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.

The Logitech Z623 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 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 we would recommend that you go easy with it. 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.

Upon first opening, you’ll notice that 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. We randomly streamed all kinds of tracks for over a couple of hours. Yes, such speakers do have a break in period, and although the Logitech Z623 sounded great during the break-in period, it was only after a couple of days that 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. Because these speakers are great at meeting specific frequencies and directing them, you get a sense of direction from each sound. 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. These babies are loud and shameless! After the break-in period, the volume had no effect on 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.

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 great bass, this 2.1 speaker is easily the most adept dual speaker setup we have ever come across.

For those wanting Bluetooth connectivity, all you need to do is to buy the inexpensive Logitech Bluetooth Audio Adapter for Bluetooth Streaming and you’ll be able to link up your devices to these speakers and have an even more complete experience.

Summary

The sound is deep and rich, and the most ‘three-dimensional’ we’ve ever heard from a 2.1 system. The Z623s are definitely worth your money, at least if you don’t need surround sound. They’re powerful, can be made to produce great sound with a little tweaking, and are convenient for a desktop setup. Highly recommended!!
