Well worth the wait. The product itself is absolutely flawless. Excellent built quality, excellent packaging and excellent performance. My living room is struggling to keep itself together and furniture in place. I was about to give 4 stars due to the delivery was delayed a couple of times (and which nerd doesn't get disappointed about delays) but with the current world situation I'm guessing that getting components in time is out your hands. In short, I'm very pleased with the product.Johnny Smed Jakobsen
Fantastic…! It met all the expectations I had after all the good reviews I read about this product - Arendal 1723 2S subwoofer - when commissioned according to the settings in the manual and Proper positioning in space I was enveloped by a captivating and round sound… even at moderate volume in an area of 60 square meters is absolutely enchanting… now I feel the music not only hear it… Thank you Team Arendal Sound for a fantastic product…and was a pleasure doing business with your…shipment was exemplaire.Dan Lucian Afrasanei
Packed very securely with multiple layers of cardboard and foam, as well as a waterproof outer sheath to withstand the harsh international logistics transit. The subwoofer itself is extremely beautiful and easy to set up with the free bluetooth app. One of the cleanest and deepest sounding bass I have experienced in my system for both movies and music (using a HSU ULS-15 mk2 as well), and the ability to set up a separate system with separate eq setting for movies and music (by using both XLR and RCA inputs with a 12V trigger for one of the inputs) is a big plus for my system.Nick
Amazing quality, amazing performance. Got 2 of these for a small room and was bit worried it might be too much, how wrong was i.. got them to match perfectly with rest of my setup and the small room with the exellent adjustment possibilities. Very clean deep and accurate bass with strong punch. Can play very loud even in small room with different eq settings, no more shaking the entire house unless wanted to! No matter how loud you play the subs stay put, no cabinet resonance at all.Roni Nurkkala
Très bon produit.Loïc
wertig - wohnraumtauglich - tiefer Bass -FJ
Habe mich letztendlich für einen zweiten 1723 2S entschieden. Einmal für eine bessere Verteilung des Basses, um Basslöcher zu vermeiden, und um trotz Antimode noch mehr Raummoden zu eliminieren. Um mehr Bass ging es dabei nicht, dafür hat auch 1 Subwoofer gereicht. Das Ergebnis hat meine Erwartungen übertroffen, eine perfekte Raumverteilung, noch mehr Präzision und verbesserung der Raummoden. Mittlerweile ist auch die App verfügbar, womit sich die Subs bequem und perfekt steuern lassen.Andre Ludwig
Brilliant sound and a lot of power!Kent Almstrand
Beauty and the beast. I have owned many great subs under the past 20 years, including velodyne hgs 18, xtz cinema 3×12 and svs sb 16 ultra, but this is my first sub with dual opposed drivers and my first norwegian sub then. Not yet played in but I can already hear bass notes that is very impressive at moderate volume then. Power and beauty in one really awesome and impressive sub then. 5 stars and 2 thumbs up then. 😁👍👍Ulf Larsson
An excellent subwoofer.Daniel Engovatov

Dual drivers, twice the fun. 1723 Subwoofer 2S offers an exceptional balance between perfect music reproduction as well as sheer bass depth and output. Utilising two of our proprietary 13.8″ drivers, driven by our smart 1200W RMS Avalanche 1200 IQ amplifier that offers ample adjustability for any setup. The cabinet is sealed and made of HDF, and is sized to provide an optimally damped system that produces deep, undistorted musical bass with a complete lack of smearing or coloration.
The dual opposing, force-absorbing driver layout delivers clean, deep bass, without cabinet movement subtracting anything from the driver output.
Literally startling dynamics. We believe this the world’s best subwoofer for music. At any price level.
Technical specifications
EQ2 24-200Hz (+/-3dB)
EQ3 33-200Hz (+/-3dB)

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.

CEA 2010
CEA-2010 is measured at 2m distance, following current guidelines. CEA-2010 measurements should be presented in 1m Peak measurements currently, although many are still using 2m RMS, so we include these as well.
Please note that our vented design is extremely difficult to accurately measure as the port and driver are on different planes. We are suffering some output on CEA-2010 measurements for this reason.
