Unfortunately, it was too good to be true. The central unit, which is integrated, and the woofer are quite good, with a variety of connections. The radio works fine, and the Bluetooth has no issues. However, the speakers were not good. The two rear satellites were defective as they were crackling and distorting the sound even at very low volume. Fortunately, the product was returned, and I will go for something better.

The speakers I received have a faulty front satellite (it produces sound of lower volume and distorted). However, the rest, which probably work correctly, do not have good sound quality, in fact in simple tests of the operating system they seem to sound slightly different. This is justified as they are not professional speakers. Otherwise, they do not distort even at relatively high volume. For the price of 139.99 that I bought them, I think they are probably not worth it. I may have simply gotten a defective product, I cannot know.

I could rate as particularly positive both their ability to connect to almost any signal source and their strong bass, however the distorted sound of one satellite overshadows everything.

Attention: The optical and coaxial inputs are only PCM, so in order to truly hear 5.1 sound, you must necessarily use the 3 pairs of audio cables (3 double jacks to RCA) provided. It does not support Dolby Digital or DTS. However, they do some kind of distribution to the rear and center even with the stereo input in these ports. The "5.1" result is not satisfactory.
