The JBL BassPro Nano is a compact powered subwoofer featuring a 6"x8" shallow-profile woofer and a built-in 100-watt RMS amplifier, delivering deep bass in a space-saving design. It offers adjustable controls like a low-pass filter (50-150 Hz), bass boost (0 to +12 dB at 50 Hz), and a phase switch (0 or 180 degrees), along with line- and speaker-level inputs for flexible installation. The subwoofer's die-cast anodized aluminum enclosure ensures durability and minimizes rattles, and it includes a wired remote control for convenient bass level adjustments from the driver's seat.
