Outdated Product
Low-cost version of a 2.1 computer speaker system, consisting of a subwoofer and two miniature satellites. Of the 11 watts of total power, exactly 5 watts falls on the “sub” itself, and the remaining 6 watts are scattered between the speakers. For the sake of cheapness, all parts of the speaker system are assembled in plastic cases. To connect the speakers, two plugs are used: one for power supply from the computer's USB connector, the second — miniJack 3.5 mm for connecting to a sound source. Defender Z4 produces a frankly flat sound and is definitely not suitable for music lovers. The audience of the 2.1 kit is undemanding users who need speakers for the most common tasks. As they say, just to play. Adjustments in the audio system lend themselves to the sound volume and increase / decrea...se in bass. The rotary knobs for this case are placed on the front panel of the subwoofer case. There is also a light indicator of the connected power in the form of a green light with the signature "Power".

Model overview based on user reviews  
The Defender Z4 is a 2.1 speaker system that offers basic sound quality, described by a user as "better than nothing." The system includes features like bass control and connects via a mini-Jack (3.5 mm). It has a frequency range of 50 – 20000 Hz, with a total speaker output of 11 W. The subwoofer, however, has been criticized for producing "cartoonish" sounds that might have been acceptable in the 90s but fall short by today's standards, achieving only a "3" on a five-point scale at maximum bass. The speakers are made of plastic and are USB port powered, with the volume control located at the front. Overall, the user does not recommend this product, highlighting the subwoofer's lackluster performance.

subwoofer with "cartoonish" sounds
better than nothing
It feels like the sub is from Disney cartoons. It would sound perfect there. At maximum bass, you might achieve something like a "3" on a five-point scale. Maybe for the 90s, this sound would have been somewhat acceptable, but not anymore.
