Firstly a tunable crossover lets you tighten up the low-end by varying the frequency response from 50Hz all the way up to 200Hz.

You even get a number of additional features with the Sony SACS9 which makes it a much more convenient and easy to use home theater subwoofer. Any form of unwanted noise is also prevented further as the waves of noise are acoustically absorbed while damping the vibrations within the cabinet, thus giving you much more clear and noise-free audio quality from your active subwoofer. Moreover, due to the Mica Reinforced Cellular (MRC) woofers you get a much better sound quality with deeper bass as the fiber on the woofer holds its shape rigidly even when playing audio, making no compromises on the sound quality.

Options like the Polk Audio PSW505 BIC America F12 come with a better, greater power output which gives you a much more powerful bass which is neither too boomy nor distorted, so if you have a bit more money to spare, these might be better options worth considering. Additionally, the bass reflex duct that suppresses any unwanted noise gives the subwoofer a better sound reproduction and therefore a bass that still sounds pretty powerful and deep despite not having that high a power output.

However, paired with the frequency response range of 28-200Hz and the cone diaphragm of the speaker you still get a powerful low-end sound which is both clear and crisp with a good amount of resonance. The amplifier comes with a 115W peak power output which although moderate, does fall behind with a continuous power output of 34.5W. Power output is pretty low for the price.
