The subwoofer can also be mounted upside down and used as a downfire.

Functions include HE-Lii technology for high efficiency and low impedance amplifier performance without changing the power supply. The 2S² design allows for downward positioning to enhance low-frequency extension or a connection system for more punch and definition. The SSP (Sub Smart Plug) connection block provides a plug & play connection for easy and safe disconnection of the box.

Dynamic Bastracking (DBT) monitors the input signal in real time, detecting earlier peaks that, if not processed, could cause the amplifier/subwoofer system to distort uncontrollably when pushed to maximum power.
