1723 Monitor THX

Select finish

Big sound doesn’t always mean tower speakers. The 1723 Monitor is proof. Designed to deliver the performance of our 1723 Series in a more versatile form, it combines clarity, scale, and control in a speaker that adapts to your space.

With dual 8″ custom drivers, a waveguide-loaded 28mm tweeter, and the flexibility of sealed or ported configuration, the Monitor delivers precision and punch — whether it’s standing proud on a pair of heavy-duty stands or anchoring your front stage.

Looking for a smaller speaker without stepping down from benchmark sound? The 1723 Monitor is made for serious listeners who want more and know it when they hear it. With a 60-day risk-free home trial and a 10-year warranty, it’s a choice you can trust.

BIG SOUND.
HONEST DETAIL

It’s THX Ultra certified — not just for the badge, but because it meets the strict standards for scale, accuracy, and headroom in demanding home theater environments.

The custom waveguide housing a 28mm soft dome tweeter and dual driver array aren’t just about output. They create a wide, immersive soundstage that stays detailed and natural, even at high volume.

Its 2-way crossover ensures clean integration and vocal focus, while the sealed or ported design gives you tuning control. Whether it’s music or movies, the 1723 Monitor delivers clarity and depth far beyond its size.

“So addictive, you find yourself looking for excuses to re-watch things.

“The Arendal 1723 THX speakers should be at the top of your shortlist whether you want speakers for a dedicated home theater or speakers that will outperform with every movie you watch.”

This speaker is truly a high-end speaker in every regard possible and is none like other affordable products I have reviewed.”

BUILT FOR
SERIOUS SPACES

The 1723 Monitor is designed to perform and built to last. Every cabinet is made from high-density fiberboard (HDF), internally braced, and finished in hand-painted satin paint. It’s a solid, refined foundation for benchmark sound.

From the sculpted waveguide to the magnetic grilles, every detail reflects our Norwegian design ethos: purposeful, precise, and proud. Whether on stands, shelves, or wall-mounted, this speaker earns its place in any room.

BUILD YOUR
REFERENCE SYSTEM

The 1723 Monitor is as flexible as it is powerful. Use a pair as front left/right channels or combine with the 1723 Center and Surrounds for a full-scale theater. Add 1723 S Height speakers for overhead effects — or go all-in with a matching subwoofer.

For the low end, choose the compact 1S or the high-output 2S — both tuned to deliver depth and detail that complete the system.

ENGINEERING 
EXCELLENCE

  • CABINET

    Constructed from inert HDF with internal bracing to eliminate unwanted resonance. Clean lines and rock-solid feel.

  • ENCLOSURE TUNING

    The cabinet can be run sealed for tight, accurate bass or vented for deeper extension — giving you the flexibility to tailor performance to your room and preferences.

  • FINISH

    Available in hand-painted Satin Black or Satin White. No vinyl wraps — just a clean, durable premium painted finish designed to last.

  • MAGNETIC GRILLES

    Free-flowing metal cores wrapped in acoustic cloth preserve sound and soften the look. Neodymium magnets hold them in place — no plastic pins, no visible hardware. With rubber buffers to protect the finish, they’re made to look and sound right, on or off.

  • BINDING POSTS

    Premium rhodium-plated speaker terminals mounted on an aluminum backplate for a secure connection — whether you’re using banana plugs, spades, or bare wire.

  • TWEETER AND WAVEGUIDE

    28mm synthetic soft dome tweeter in a custom waveguide for wide dispersion, improved integration, and natural high-frequency response.

  • MID-BASS DRIVERS

    Dual 8″ custom drivers designed for tight, low-distortion bass and a natural, punchy midrange. Controlled, responsive, and built to handle serious dynamics.

  • CROSSOVER

    2-way design with steep slopes for smooth driver integration and reduced distortion. Tuned for clarity, imaging, and tonal balance across the entire frequency range.

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.

Polar

The charts display frequency response measured at different angles, the sum of which is referred to as power response. Much scientific research has been undertaken on this subject and a linear power response has proven a substantial impact on the overall sound, because the frequency response is more even in all directions. This means an Arendal Sound speaker will be more tolerant of differences in room shape, size, construction and materials.

Impendence

The impedance charts are electrical measurements of the loudspeaker’s resistance vs frequency.
