Powerfull….Börje Banderas
Der Subwoofer kommt punktgenau.Markus Steingrüber
Great sound. I am totally pleased. Mainly used for stereo listening in a Focal speaker setup. Great looks also.Heiko Blabusch
Best subwoofer at this price point.. nothing comes close...they take pride in their builds and the packaging could survive an explosion...the sound is simply quality 👌Mr Mclean
Very heavy and large Subwoofer. But a great tight en deep bass. Installing is very easy. Build quality is ecellent! Keep in mind that the subwoofer is really big and heavy to. This was the first product from Arendal and never disapoint me in 3 years that i own it now.Danny Geurtsen
Absolutely worth the money.He Ku
It’s a beast. Just a shame it got replaced and i can not buy a second one now :(Daniel
So powerfull. An absolut dream. Perfect qualitiy and a great value for money.Nico
I expected a better subwoofer, but he wasn‘t. He was spectacular! He played more deep and fuller than the old one, at the exact same position. And the old one was quit good. I didn‘t regret my decision to go a new way. The quality of the materials is great.Dean Symannek
As expected...Rune

Frequency response
Frequency response does not reflect maximum output but shows its true response in a anechoic chamber. Typically you will see an elevated response in the bass response below 40Hz in room due to room gain, which can add around 6dB pr. octave under 40Hz depending on the size of your room.
