The J-INFRA is the INFRA subwoofer for the J-Series. It is an actively driven 2-way bass-reflex design and extends the frequency response of a J-Series system down to 27 Hz. It has two bassreflex chambers containing three 21″ drivers, two facing forward and one facing backwards. The cardioid dispersion pattern resulting from this arrangement avoids unwanted energy behind the system that greatly reduces the excitation of the reverberant field at low frequencies and provides the highest accuracy of low frequency reproduction.

The J-INFRA can only be used in ground stacked configurations in conventional left/right setups as well as arranged in a subwoofer array
