1723 Subwoofer 2

Legacy product

The Subwoofer 2 is the pinnacle of bass accuracy. Using two of our proprietary 13.8” driver driven by our 1000W RMS Avalanche DSP amp, the cabinet volume has been sized to produce an optimally damped system, producing low distortion, naturally deep bass, that drops and drops. A further performance edge is provided by our dual opposed, force cancelling driver topology to deliver clean deep hits, without cabinet movement subtracting anything from the driver output. To be safe, we’ve over engineered the cabinet with inch thick walls and two inch thick baffles, so you won’t feel a thing even when crashing out the most bombastic soundtracks.

EISA award

Even driven to reference levels which is normally too loud for my ears the 1723s never distorted or cracked under pressure. This cant be said of other popular brands that I have heard.

Spare Change

When we are talking about clean and effortless deep bass, we have hardly heard it better than this “doomsday machine” from arendal.

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.
