BUILT FOR IMPACT
AND IMMERSION

Surround speakers aren’t just filler. They carry the atmosphere, the echoes, the tension — the subtle cues that make a scene feel real. The 1723 Surround S is engineered to excel at that role. Its forward-facing 6.5” mid-woofer and 28mm waveguide tweeter deliver clarity and punch where it matters, while the angled dipole side drivers expand the soundstage beyond your walls, pulling you deeper into the moment.

It’s not just what you hear. It’s how completely you’re pulled into the story. From creeping footsteps behind you to the swell of music wrapping around the room, the Surround S brings emotion, detail, and movement to every scene.

“Offering a powerful performance from easy to accommodate cabinets, Arendal Sound’s THX Ultra-certified multichannel package brings Hollywood to your home theatre. Design and build quality are exceptional for the price.

“The 11.1 channel setup is by far the best sounding system I´ve owned…” “the amount of chest vibrating bass was crazy…”

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

CLEAN DESIGN.
READY FOR CINEMA

The 1723 Surround S looks right at home in any serious setup. Its sealed cabinet is compact and solid, made from dense HDF and finished in our hand-painted Satin Black or Satin White. It mounts cleanly on side or rear walls, giving you flexibility without visual clutter.

From its subtle design to its premium materials, the Surround S reflects the best of our Norwegian approach: precise, minimalist, and built to stand the test of time. It blends into the room visually, but never in performance.

BUILD YOUR
REFERENCE SYSTEM

Use the Surround S as part of a full 1723 Series S system. Pair with Monitor S or Tower S as mains, Center S for dialog clarity, and Height S for overhead effects. The shared voicing ensures consistent tonality and performance throughout your theater.

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.
