BUILT FOR THEATER.
READY FOR MUSIC

With its ported cabinet design, the 1V delivers massive low-frequency output with effortless power — but always under control. Whether you’re watching an explosion rip across the screen or feeling the low swell of an organ pedal, it moves air with confidence and authority.

Despite its size, this isn’t a one-trick sub. With app-controlled presets, flexible tuning, and detailed EQ options, it adapts to your space and preferences. Choose between ported or sealed modes depending on your goals — ultimate output or maximum precision. Either way, it delivers more than you expect.

“All of these luxury touches, together with their immaculate style and specifications, make these speakers among the best I’ve tested and certainly an AVS Top Choice for 2023.”

“Their sheer solidity, together with their elegant industrial design, raises them to luxury-class products.”

“It is a balance of really good performance for movies as well as music and a rock-solid construction.”

OVERBUILT.
NORWEGIAN BY DESIGN

The 1V is constructed from dense CNC-machined HDF with internal bracing and acoustic damping. Finished in hand-painted Satin Black or Satin White, it reflects our Norwegian design values — clean, minimal, and engineered for real-world longevity.

It comes fitted with rubber-isolated feet, weighs over 45kg, and occupies a commanding presence in any room. And with a single, oversized rear port – 2.5cm tall and 35cm wide – you have the flexibility to tune your system for maximum slam or precise subtlety.

ENGINEERING  EXCELLENCE

Driver

13.8″ custom long-throw driver with oversized magnet structure, aluminum shorting rings, and vented pole piece for clean, distortion-free performance — even at extreme excursions.
AMPLIFIER

Avalanche 800 IQ amplifier with 800W RMS power, parametric EQ, low-pass filters, presets, and app control. Tailored to match the 1V driver and enclosure for maximum control and reliability.
ENCLOSURE

Ported HDF cabinet with internal bracing and acoustic damping. A single wide rear port allows for sealed or vented operation — designed to move serious air without chuffing.
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.

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.
