The Helix U 8A and U10A are an excellent choice for getting bass from a very small enclosure. The built-in amplifier is far more powerful than usual in such small active subwoofers, with a continuous output of 180 watts. The aluminium cast housing has a mounted element with a very rigid aluminium cone.
Suitable for mounting under the front seat, in the back of the rear seat, on the side of the boot, on the rear wall of a truck, etc. etc.
