1723 Bookshelf S THX

Select finish

The 1723 Bookshelf S delivers the same sonic DNA as our Monitor S — but in a smaller, cabinet designed for maximum placement flexibility. With a custom 6.5” woofer, waveguide tweeter, and sealed cabinet design, it’s engineered to shine on a stand, shelf, or wall.

Despite its compact size, this is a serious speaker with high-performance ambition. Whether you’re building a small-footprint stereo setup, a compact front-stage cinema layout, or outfitting height channels for Atmos, the Bookshelf S combines precision engineering with the flexibility to fit almost anywhere. It may be scaled down, but it plays with full-scale confidence.

It’s about delivering an experience that feels far bigger than the box it comes in. And like every speaker in the 1723 Series S lineup, it comes with a 60-day risk-free home trial and a 10-year warranty — so you can enjoy it with complete confidence.

ENGINEERED FOR
SMALLER SPACES

Don’t let the size fool you. The 1723 Bookshelf S features a full-sized 6.5” driver and the same 28mm soft dome tweeter found throughout the 1723 Series S. The result? Dynamic punch, detailed mids, and sparkling highs — all in a compact enclosure that fits where towers won’t.

This sealed design keeps low-end control tight and precise, making it ideal for smaller rooms, desktop setups, and rear or height channel duties. Whether you’re aiming for nearfield clarity or immersive surround detail, the Bookshelf S adapts beautifully to your space. It may be small, but it delivers big-room sound with unmistakable Arendal character.

“The 5.1 system of Arendal delights with its outstanding musicality and a highly dynamical ability despite the compact format.”

“Arendal Sound Bookshelf S is one impressively playful, lively, competent and engaging compact speaker!”

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

BUILT TO FIT.
DESIGNED TO LAST

The 1723 Bookshelf S features a compact cabinet made from high-density fiberboard (HDF), internally braced to eliminate unwanted resonance and finished in our signature hand-painted satin black or white. Magnetic grilles and clean Scandinavian lines ensure it looks as refined as it sounds, whether displayed proudly or integrated discreetly into your space.

It’s built to reflect our Norwegian values of purposeful design, honest materials, and engineering without shortcuts. From its finish to its internals, every detail is crafted for lasting performance and timeless appeal.

BUILD YOUR
REFERENCE SYSTEM

Match the 1723 Bookshelf S with a 1723 Center S for a space-saving cinematic front stage, or addit as rear or height channels to your existing 1723 S setup. Its shared tuning ensures tonalconsistency across the system, so every transition feels natural and cohesive.

Add a 1723 Subwoofer for full-range performance that brings out the deepest details in your music or movies. Or simply enjoy the Bookshelf S as a precise, sealed design for nearfield listening, where speed and control matter most. However you use it, the Bookshelf S adapts with confidence — delivering immersive, reference-level sound in rooms where other speakers struggle to fit.”

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.
