1723 Subwoofer 3

Legacy product

The Subwoofer 3 is our statement of the fine balance between pure bass accuracy and sheer bass depth and output. Using two of our proprietary 13.8” driver driven by our 1000W RMS Avalanche DSP amps, the cabinet volume has been increased over the Subwoofer 2 to increase efficiency and allow us to add super-quiet, slot port loading to increase bottom end output. Plug the port for greater accuracy, or unplug for greater output. Utilizing our dual opposed, force cancelling driver topology to deliver clean deep hits, without cabinet movement subtracting anything from the driver output, we have created a state of the art subwoofer to drive even the largest rooms with massive, deep, low distortion bass.

Professional reviews

1723 Monitor S scores the most points in combination with movies and music, but it is a hifi-speaker that stands out really well in the price range.


Arendal Sound has put together a system that for the time being is the most impressive you can experience in this price range.


Subwoofer 3 sounds breathtaking and violent and with surplus in heaps, and it plays movies and music equally well. You decide. Subwoofer 3 delivers.


With the 1723 system, Arendal has delivered a real highlight for home-cinema fans. The extreme dynamics, the effortless precision and the flawless finish make the Arendal system a real recommendation for ambitious movie fans.


It's not often we hear so insanely tough home cinema like this. Arendal Sound takes the soundstage and just thrusts it into the room. The subwoofer especially hammers and shakes the whole body loose, without even trying.

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.
