1723 Center S THX

Select finish

The 1723 Center S is built for one purpose: clarity where it matters most. In home theater, your center speaker carries up to 80% of the action — and the 1723 Center S makes sure every word comes through with detail, power, and precision.

With the same 6.5” drivers, waveguide tweeter, and HDF cabinet construction as the rest of the 1723 S family, it delivers seamless front-stage integration and tonal consistency with your main speakers. It’s compact, powerful, and tuned to keep voices locked to the screen — no matter the volume.

And with a 60-day risk-free home trial and a 10-year warranty, it’s a confident step into serious dialogue.

ENGINEERED FOR
UNDERSTANDING

The 1723 Center S uses a horizontal MTM (midwoofer-tweeter-midwoofer) layout. The custom 28mm tweeter is set in a precision waveguide to ensure broad dispersion and clear articulation, even off-axis.

Whether it’s the crackle of a whisper or the roar of a battlefield, every word cuts through — clean, locked to the screen, and exactly as it was meant to be heard.

Behind it, a carefully tuned crossover and braced, ported HDF cabinet allow for deep bass extension and tight control. This isn’t just a support act — it’s the vocal anchor of your system. Movie night never sounded this good.

“…it’s no surprise that the Arendal 1723 Series S has been rightfully recognized as an AVS Top Choice for 2023.”

“I’m not kidding, I literally experienced details I didn’t know were there. I could listen to these speakers all day every day, there is absolutely no fatigue or strain.”

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

BUILT FOR
THE SPOTLIGHT

As the Center S is designed to sit directly below your screen, it’s built with the same attention to detail as every 1723 model. The thick HDF cabinet is fully braced and finished in hand-painted satin black or white, while magnetic grilles and chamfered corners, give it a clean, minimal look that still feels premium.

And like all our speakers, its design reflects our Norwegian roots — deliberate lines, purposeful engineering, and quality that lasts.

BUILD YOUR
REFERENCE SYSTEM

Every product in the 1723 Series S lineup is designed to work together with consistent voicing and scale. Because when the system kicks in and the story takes over, you’ll remember why a great night in can be just as powerful as a rowdy night out.

Pair the 1723 Center S with the 1723 Monitor S, Tower S or Bookshelf S for seamless front-stage performance. Add Surround S and Height S for wraparound immersion, then finish with a 1723 Subwoofer for room-shaking realism.

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.
