Let’s start with this powerful under-seat subwoofer from YaeCCC. Surely the maximum output power of 600Watts is decent but this amount of power can be applied only for short periods without causing damage. If you want to find out how much of continuous power your subwoofer can handle you should look the RMS (root-mean-square) value. These tend to be much lower than the maximum output ratings but are more accurate in representing the true capability of your equipment. RMS of 180Watts combined with a frequency range between 20Hz and 150Hz makes this compact under-seat subwoofer pretty powerful when it comes to the depth of bass reproduction. In case you find yourself disappointed with the sound quality check your main unit first – if its signal is not strong enough it will affect the work of the subwoofer.
