I have bought the investment 2 months ago because it is designmäßig a real looker. The facility has a decent performance, consequence is that if you want to hear something quieter music has to adjust the volume to 2 or 3 down and that is where the trouble starts. The part roars! Why? Because LG necessarily had to install a permanently running fan. The system is only recommended for those who want to hear a) only loud music or have other noises in the room that drown out the noise.
