Fantastic build quality and very user friendly interface on the amplifier.
This sub has massive headroom and has epic depths when amplifying kick drums.
It has no floor noise and runs really cool....I've yet to see the limit led come on or the fans kick in.
For an 18, it is compact and easy to handle.
If I have any criticism then I would suggest factory fit castors or alternatively buy a castor board.
Price reflects the quality
I am very, very happy with this sub and when paired with the EKX 12P, makes for a formidable pa.
