1723 Subwoofer 2S

Based on 5 reviews

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 is the world’s best subwoofer for music. At any price level.

This amplifier doesn’t only look good, it has market-leading performance and technology. Unbeatable and unseen at this price. Boasting real 1200W down to 10Hz.

Get all settings in your hands. This is not a kindergarten app for subwoofers.



    We have customized a new slick puck-design mounted with M6 bolts. They create extreme stability against the floor. Branded with the Arendal Sound logo.

  • 1723 AVALANCHE 800 / 1200 IQ

    The term “intelligent” is rarely used in the audio industry, especially for speakers and subwoofers. The new Avalanche 800 IQ & 1200 IQ subwoofer amplifiers are two more exceptions from Arendal Sound, when it comes to performance and technology.

  • 1723 NEW 13.8″ WOOFER

    50% increase in excursion and performance with impeccable dynamics.


    Twice the fun! Dual Opposing Driver Configuration adds more cabinet stability where forces are canceled. Meaning improved dynamics and room response.


    We are especially proud of our new exclusive and fully custom made grills. For all Arendal Sound speakers we have made a free flowing, perforated metal grill which does not affect sound quality.

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.

Professional reviews

  • “If you are looking for something that is quite compact and you still want some home theater impact, this is a fantastic option.”

  • I hate to be the bearer of bad news, but if you don’t have good speakers, you don’t have a good sound system. Period. The speakers you use have a disproportionate impact on how your music sounds.

  • “Hard-hitting tight bass that hits you in the chest.”

  • “This system will make an incredible home theater setup.”

  • The build quality is terrific for the class, and the 1723 Subwoofer 2S is built like a brick.

  • In light of these strong characteristics, it’s no surprise that the Arendal 1723 S series has been rightfully recognized as an AVS Top Choice for 2023.

  • Arendal makes extraordinary speakers and subwoofers, there’s simply no other way to say it.

  • “Looking for speakers that are good for both music and movies? Put these on your shortlist”

  • To put the price into perspective, a M&K X-12 subwoofer in comparison costs about 4000€ and doesn’t have anywhere near the same adjustability and it has considerably less output.

  • If you want to enjoy home cinema sound at the highest level and physically feel powerful, precise low-frequency sound, the 1723 S2 subwoofer from Arendal is ideal.
