Select finish

The 1723 Subwoofer 2V is our most capable performer — a dual-driver, ported subwoofer designed for commanding output with remarkable control. It brings seismic energy to movie night and complete precision to music listening, all from a single chassis.

With two force-cancelling 13.8″ drivers, an oversized slot port, and our Avalanche 1200 IQ amplifier, it’s made to move air with authority and keep the details intact. Think size. Think scale. Think control.

THE APEX OF
ARENDAL BASS

Dual 13.8″ drivers, a massive 4 x 40cm rear port, and a cabinet tuned for effortless composure. The 2V is built to handle deep cinematic rumbles, musical subtleties, and long sessions at reference level without breaking a sweat.

Its opposing driver layout cancels mechanical vibration, and the port is tuned for speed and power without noise or bloat. Switch to sealed mode for a tighter, more controlled character — ideal for music or more compact rooms. This isn’t just our biggest sub. It’s our boldest.

“One of the best subwoofers I have ever heard, regardless of price.”

“The Arendal 1723 SUB 2V is a real “beast” and an ultimate recommendation for true home cinema enthusiasts!”

“They seem to get everything right; looks, engineering, sound quality, features, these folks miss nothing.”

BUILT TO SHAKE.
ENGINEERED TO LAST.

The 2V is constructed from thick CNC-machined HDF, internally braced, and fitted with an oversized 4cm x 40cm port to ensure serious air movement without distortion. Its dual opposing drivers cancel mechanical force for cleaner, quieter operation, even when output is seismic.

It comes finished in hand-painted Satin Black or Satin White, with rubber-isolated feet and Norwegian design principles baked into every line. Practical, minimalist, and uncompromising

ENGINEERING  EXCELLENCE

Driver

Dual 13.8″ custom long-throw drivers in force-canceling configuration. Aluminum shorting rings, vented pole pieces, and high-efficiency suspension for tight, deep response with minimal distortion.
AMPLIFIER

Avalanche 1200 IQ amplifier with 1200W RMS power, parametric EQ, low-pass filters, presets, and app control. Built for high-output control and long-term reliability. Its high damping factor ensures precise control over both drivers, eliminating overshoot and keeping bass tight and accurate at all volumes.
ENCLOSURE

Ported HDF cabinet with internal bracing and oversized 4 x 40cm slot port. Can also be run sealed for tighter bass response.
ISOLATION

Rubber-damped feet provide mechanical isolation, improve stability, and reduce energy transfer to the floor — ideal for both hard and carpeted surfaces.
FINISH

Hand-applied Satin Black or Satin White multi-layer paint finish. No vinyl. No shortcuts.

APP-CONTROLLED.
ROOM-READY

The Avalanche 800 IQ amplifier provides 800 watts of clean RMS power, paired with intelligent DSP and full app control for iOS and Android devices. You get phase adjustment, low pass filtering, variable EQ curves, and multi-band parametric EQ — all from the listening position. Whether you’re fine-tuning to your room or switching presets for music vs. film, it’s bass on your terms.

BUILD YOUR
LOW-END FOUNDATION

The 1S makes an ideal match for 1723 Tower or Monitor setups when sealed performance is the right call — whether for room acoustics, placement needs, or personal preference. Run a single-driver 1S for tight, articulate bass reinforcement that won’t dominate your system — or use two for added balance, output, and symmetry.

It’s not the most extreme subwoofer we make — but for many listeners, it’s the most complete. Everything you need. Nothing you don’t.

Frequency

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.
