Pros & Cons

It is very powerful and the sound remains clear and tight. It is a great option for large rooms.
Many input ports make this solution versatile.
It is easy to blend with other speakers you have. It also features a dual-band parametric equalizer.

This subwoofer is very heavy – it is better to find the right place for it beforehand.

The output bass is clear at different frequencies. This model is a good option both for audiophiles who prefer to listen to their favorite music and for movies.
The sealed design makes the output sound deeper.
Good integration controls.
