The novelty of Ground Zero's Radioactive SQ collection is finally here! The goal of the Radioactive SQ series has been the best possible sound quality in its price category. Klippel optimization has been used in the design to make the structure of the speaker element polished to the last level of functionality.
The collection has been developed on the basis of the previous Radioactive AL collection, in the design work of which Ground Zero's Finnish importer Audioimport (nowadays AI Group) has been heavily involved. The elements work excellently in typical car installation locations. Instead of casing, Midbasso works better in door installation without building separate casings.
Midbasso has an aluminum cone and rubber suspension. The lower-than-normal 3-ohm impedance helps to extract more power from the instrument or amplifier. The treble has a silk calotte treble. Separate crossover filters for midbass and treble
