RCC 600 was the world's first reactance canceling, vibration free in-wall subwoofer designed for applications where customers want high performance bass without the typical freestanding subwoofer box in the living space. High performance drivers were developed using a patented Dual Drive Motor Assembly, which provides high efficiency and high excursion. The subwoofer module configuration has four drivers in opposing pairs. The baskets are rigidly attached to one another to allow the reactance forces generated by the cone motion to always be equal and opposite, cancelling out one another dynamically. This versatile in-wall subwoofer can be used in an infinite baffle or paired with an Artison in-wall or in floor cabinet depending on installation.
