This subwoofer meets all requirements for a home system, for example. TV and multimedia. Even in acoustically critical rooms (tiled floor, walls with sharp angles) of the woofer still appears clear and without brawny roar. I use each one of these systems as a woofer in each stereo channel through the phase switch and the fine frequency adjustment of the sound is optimally adjusted. Highly recommended for small budgets and big claims. :-)
