Earthquake’s newly released SUB6 and SUB8 passive subwoofers powered by the SWS patented design deliver impressive bass from a shallow space. In fact, these subwoofers deliver twice the excursion of any other conventional speaker with the same mounting depth. Impressive bass performance can now be invisible allowing the home integrator or installer to use these subs in 2x4 walls or ceilings with round or square edgeless and paintable grilles (both included). The SUB6 and SUB8 are also equipped with a 100% copper wire crossover network to filter out voices and instruments leaving you with pure bass. Constructed from long-lasting and high-quality components, the SUB6 and SUB8 are a great choice to quickly and efficiently add more bass to any room whether it is for new constructions or existing home theaters.
