1723 Surround THX

Select finish

Surround speakers don’t just fill space — they create it. The 1723 Surround is built to immerse you, placing you at the center of the story with a design that goes far beyond standard rear-channel solutions.

At the heart is an 8″ front-firing driver and a waveguide-loaded 28mm tweeter, paired with custom full-range drivers in dipole configuration on angled side baffles. This unique TriAxial layout delivers a wide, diffuse sound-field while maintaining clarity and impact, blending effortlessly into a full 1723 system.

Whether it’s a whisper behind your shoulder or the rush of a passing car, the 1723 Surround brings it to life — with benchmark precision and cinematic scale. With a 60-day risk-free home trial and a 10-year warranty, you can trust it’s designed to deliver and built to last.

BIG SOUND.
HONEST DETAIL

The 1723 Surround’s TriAxial design means you don’t have to choose between detail and atmosphere. The front-facing 8″ driver and waveguide tweeter provide focused, dynamic output — while the angled side-mounted full-range drivers expand the soundstage with natural, enveloping effects.

This combination creates a seamless sense of space. Whether you mount them on the side or rear walls, the 1723 Surround delivers precise placement and a smooth surround bubble that pulls you deeper into the moment.

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

“I approached this review with high expectations, considering my previous experience with the 1723 THX Towers last year. These expectations were not only met but exceeded.”

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

MADE TO FIT.
BUILT TO PERFORM

The 1723 Surround is crafted to blend into your room — visually and acoustically. The HDF cabinet is rigid and acoustically inert, with a hand-painted satin finish and a compact footprint. Each speaker includes a wall-mount bracket for simple, secure installation. Sealed by design, they work in tight spaces while delivering the performance you’d expect from a full-scale surround speaker.

Magnetic grilles keep the look clean, while the robust build and premium materials ensure they’re ready for long-term reference use. It’s Arendal quality, from the inside out — rooted in Norwegian craftsmanship that values thoughtful design, durable materials, and an unwavering commitment to performance.

BUILD YOUR
REFERENCE SYSTEM

The 1723 Surround is perfectly matched to every other speaker in the 1723 Series. Whether you’re building a 5.1 layout or a full-blown Atmos system, these surrounds help you complete the picture — with voicing, dynamics, and finish that blend seamlessly.

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.
