1723 Subwoofer 1

Legacy product

The baby of our Subwoofers, the Subwoofer 1 is still a potent beast that would top many ranges. Using our proprietary 13.8” driver driven by our 500W RMS Avalanche DSP amp, the cabinet volume has been sized to produce an optimally damped system, producing low distortion, naturally deep bass. All of the features and technology that are present in our larger multi-driver subs are present, with no corners cut. Conceived as a natural match for smaller rooms, you will be amazed how large a room the Subwoofer 1 will be happy driving.

Frequency response

Frequency response does not reflect maximum output but shows its true response in a anechoic chamber. Typically you will see an elevated response in the bass response below 40Hz in room due to room gain, which can add around 6dB pr. octave under 40Hz depending on the size of your room.
