too powerful for my living room of 18 m2 open on my kitchen. A good place for not doing everything shake. I use 15% power. Low enough to remain dry laminar event. It goes down very very low infra. I did the test with different frequencies and responds to 16 hz. The self system is well controlled. If the bass was a little sharper, he earned the 5th star.
In accentuation of my system onkyo klipsch rf 52, I HC Council. hifi test on the organ Toccada proves satisfactory but with a slight train low for audiophiles.
Value for money 4 stars / 5. Recommended for use 85% Home cinema.
