I admit that I did not expect such quality for such a price! The Sub is excellent, it lacks nothing, excellent aesthetically, excellent packaging, and objectively very good sound! Bravo to NobSound!

Very good product. I bought it to accompany two Edifier monitors and create a 2.1 system. Very simple connectivity. Satisfactory sound for the money, without distortions. I haven't tested it at maximum volume, as it covers my needs at 50% of its intensity. The heatsink on the back for the amplifier does not exceed 55-60°C in temperature.

The only negative thing I have noticed is that it reproduces any parasites that may exist in the room, from mobile phones to static and Wi-Fi. It can be annoying when playing at low volume, especially when turning it on until the circuits load properly, but it is not noticeable at high and normal volume.

I have noticed that after a while, it settles down and you can't hear anything. It could be a defect in mine, but I can't know for sure.
