Ground Zero GZIW 300
All GZIW basses feature a new updated sub-suspension, voice coil, and
IMPP cone, which is stiffened with spirals. This affects the resonance of the cone considerably,
so the renewed GZIW guarantees an even tighter kick!
Don't let the low price fool you. This element is excellent in terms of performance for its price. More design work has been done than on most manufacturers' higher price ranges. Klippel optimization involves 10 hours of testing, where the element's behavior is measured in many ways and weak points are dug out before production. This results in a very high-performance element.
Thanks to the flat impedance response, the element accepts power well. Thanks to the carefully designed voice coil and its cooling, power endurance is excellent. The long travel allows for ample sound pressure levels even at lower frequencies.
