Logitech Z623 vs Z625

AUCTION: These speakers are targeted at consumers who want to have high-quality sound but on a tight budget. You might consider the KEF LS50 Wireless speakers or the Yamaha HS series of studio monitors to produce music in your studio.

Both speakers deliver a remarkable level of sound quality for their price. The LogitechZ625 has a slight advantage over the LogitechZ623 when connectivity and power are considered. Both are great value for money, if you don’t mind the absence of Bluetooth or wireless connectivity.

There are a few things you need to consider when deciding on the type of speaker system that you want. You will need to consider your budget, your goals, tastes, space and the place you plan to use them in. While a lot of this will be subjective, here is a comparison between these speaker systems to help make your decision.

Design and build

The systems have a futuristic but minimalistic design that can be easily integrated into urban homes and offices. These speakers have the type of curves gamers will love, but they are not too extreme for offices that have a more conservative setting.

While the speakers are designed to provide a more personal listening experience, they can be hampered by a desk that is higher than normal. However, this is not an issue. The rubber bases beneath are a nice addition. They give the furniture more stability and sound absorption. This helps to avoid that annoying furniture buzz you get every now and again.

On the right speaker, you will find the bass volume control knobs. The knobs are large enough to provide a comfortable feel while you adjust. It has a nice, little feature that works in its favor.

Both systems look very similar at first glance. The main differences between these systems are their size and weight. Let’s take a look at them.

Logitech Z623 is 7.7 inches high, 4.6 inches wide and 5.0 inches deep (see image).


  • The Logitech Z623 is 18.3 lbs
  • Logitech Z625 @ 19.7 Pounds


  • Logitech Z623 measures 7.7 inches high, 4.6 inches wide and 5.0 inches deep
  • The Logitech Z625 measures 11.1 inches high, 11.9 inches wide and 10.4 inches deep

The Logitech Z623‘s lighter weight is something that all backs will appreciate, but the Logitech Z625’s subwoofer actually makes a significant difference in the sound. You should use lower frequencies.

The differences in the size of the subwoofer and speaker sizes can make both systems appear a bit flimsy. This is not an audiophile product. The sound is clear, loud, and balanced, and can fill a room from medium to large.


The Logitech Z625 combines plastic with a Medium-Density fiberboard. This gives it an advantage over the Logitech Z623, a 100% plastic product. Although neither of these materials is the most desirable, it would be unreasonable to expect much more at this price. The black finish and design are flexible enough to allow both systems to be successful.


Both the Logitech Z623 as well as Z625 have been THX-certified. This certification is the only one granted to high-end products up until a few decades ago. It seems this fact puzzles some people. This is a major strength of the company and adds credibility.

The Logitech z623 Offers:

  • Total power of 20 Watts
  • Subwoofer power of 130 watts
  • Speaker power 2 x 35 Watts
  • A frequency range that begins at 35.0 Hz and ends at 20 kHz
  • Power per channel (RMS), 35.0W

Logitech Z625, however, is a more affordable option.

Logitech HTML623 (see image) provides 2 analog inputs (3.5mm aux) and an analog RCA stereo input (no outputs though) .

  • Total power of 400 Watts/200 Watts (RMS).
  • Subwoofer power at 260 Watts/130 Watts (RMS).
  • Speaker power 2 x 70 Watts/2 x 35 Watts. (RMS).
  • A frequency range that begins at 35.0 Hz and ends at 20 kHz
  • Power per channel (RMS), 35.0W

If this sounds technical, it is because both systems offer a broad and complete spectrum of frequencies. However, the LogitechZ625 is louder.

However, neither of these systems offers an equalizer. If you want to fine-tune your mix, you will probably need to do this internally via your device. Many apps for computers and mobile devices allow you to do this. You might have to use the bass control for entertainment and gaming apps. It might be difficult to achieve a balanced sound in rooms that are prone to being ‘boomy’.


Logitech Z623 offers

  • 2 analog inputs (3.5mm aux)
  • An analog RCA stereo input with no outputs
  • A headphone output (3.5mm)

The Logitech has all the above, but also offers a digital optical input(S/PDIF), giving it a slight advantage over its brother.

One caveat: neither the Airplay nor Bluetooth versions of these systems are available. This could be a problem in an age when many people rely on their phones and devices to listen to a lot of our audio. Many of these devices do not have analog audio outputs.

No remote control or USB connectivity is available.
