UPDATE: I can say that the midrange in the EQ "ROCK" is quite good, but because the highs are "deficient," the sound seems somewhat "closed" in the low frequencies. However, as you increase the volume, it rewards you, and the highs are not at all overpowering. It doesn't consider itself powerful in terms of volume, but it's not weak either. It's just that the dynamics in the bass are misleading! In the 55-65Hz range, it has good dynamics, energy, body, and quality, which is surprising in the low frequencies!!! It has a 3.2-inch polypropylene mid-woofer and a polyamide tweeter. At high volumes, the instantaneous power consumption is around 16-17 watts, while in "bursts" of low frequencies, it reaches 21 watts! So someone who knows can understand how much the total RMS power can be!!!

Initial evaluation:
Sound:
The base of the sound is to emphasize the bass with balanced highs. For sound adjustment, it only has preset equalizers that even in "FLAT" mode, it emphasizes the bass?!?
The bass it produces is deep (subwoofer-like) and there are moments when it gives the impression of being "three-dimensional." It also performs better than other sound systems in this category in difficult parts where the bass can hit or sound dry. In the "ROCK" EQ, it can play with good intense bass from the low frequencies!!!

Total volume power of 100 watts RMS?!?!? Too good to be true!!!
For the sake of truth, you won't find RMS written anywhere on the sound system! The speakers indicate 50 watts of power, and the amplifier indicates 180 watts of power. Empirically, at maximum volume, I estimate it delivers around 50 watts RMS (I may be generous). However, this doesn't matter because it plays cleanly even at maximum volume with dynamic bass!!! I believe it won't disappoint anyone up to 20 square meters! Also, it plays louder on the radio than on USB, Bluetooth, or CD.

Sources:
USB: It only displays numbers. It reads folders.
BLUETOOTH: It works flawlessly without losing quality!!! It connects easily and with good range! I don't perceive any delay in sound or image.
RADIO: It doesn't have RDS.

It would be great if it had a line out!!!

Construction:
The build quality is at a good level! The speakers are made of MDF with a slightly textured finish. The front part is glossy-lacquered. The top and sides of the amplifier are made of metal! Unfortunately, the connection between the speakers and the amplifier is done with plugs. In other words, the cable is not bare if you want to use the speakers with another amplifier.

Power consumption:
In standby mode: 1 watt
In radio mode with volume at 10/32: 6 watts, while in USB, Bluetooth, CD: 8 watts.
10/32 is a good volume for listening to music while being able to talk to the person next to you!

In conclusion, I rate it with 5 stars for the overall value it can offer for the money! Up to 130 euros, it's a good deal!!!

The best for the money... Beautiful construction, perfect bass and at a very good price... Bluetooth was extremely convenient for me... The volume is incredible... The sound at level 4 out of 32 can be heard throughout the entire house... Even at level 32, the sound is crystal clear...

Although system 2.0, the bass is very good and powerful! Good construction and the bluetooth works great! The remote control is slow to give the command but it's a minor issue. Value for money

The remote control is a complete disappointment. It is so small that it makes it difficult to use. Additionally, its buttons do not immediately respond to commands for changes. "It doesn't always register when pressed." However, programming the memories is very easy, even without reading the instructions.
