1723 THX Series SPEAKERS

THE BENCHMARK FOR SERIOUS LISTENING

ENGINEERED FOR MUSIC. 

CERTIFIED FOR CINEMA

The 1723 Series sets the benchmark for performance and precision. Built to provide both musical clarity and cinematic scale, it’s a speaker system that doesn’t make you choose — it does both, brilliantly.

Every model in the range meets THX Ultra standards — ensuring it delivers the performance, clarity, and consistent sound coverage large rooms demand. Whether you’re listening in two channels or diving into surround, the 1723 Series delivers a wide, natural soundstage with razor-sharp imaging and deep, articulate bass. From delicate acoustic performances to all-out action scenes, you’ll hear every detail — it’s what separates a good night from a great night in.

BUILT LIKE
NOTHING ELSE

From the reinforced HDF cabinets to the custom-designed drivers, every part of the 1723 Series is engineered for control, power, and longevity. No MDF. No shortcuts. Just a focus on dense, durable materials and precision assembly that eliminate resonance and preserve sonic purity — even at high volume. Internally braced enclosures and damping layers in larger models further reduce vibrations and distortion.

This is design you can hear and craftsmanship you can trust to last for years. And it’s not just how we design, it’s where we design. Rooted in Norway’s tradition of engineering excellence, every 1723 speaker carries the legacy of our culture: practical, precise, and proud of doing things properly.

the best
OF BOTH WORLDS

The 1723 Series isn’t just about impact — it’s about balance. THX Ultra certification guarantees home theater performance at the highest level, but we’ve gone further. These speakers are equally at home in a music-first setup, with natural tonality, clean midrange, and flexible port tuning that lets you dial in the perfect low end for your space. They’re tuned to shine across genres and formats, whether you’re watching a blockbuster or spinning vinyl.

And with minimalist Scandinavian design and a choice of Satin Black or Satin White finishes, they look every bit as refined as they sound — timeless, confident, and crafted to complement any room.

Our first series is named after the year Arendal was given market city privileges.

HERITAGE
YOU CAN HEAR

1723, Arendal in Norway was granted official market city privileges — a recognition of its importance as a hub of craftsmanship and trade. That moment marked the beginning of a tradition rooted in precision, hard work, and pride in doing things properly. It’s a spirit we carry forward today.

The 1723 Series is named in honor of that legacy — a tribute to the culture and values that shape everything we make. It’s more than a name; it’s a reminder of where we come from and why quality matters. Every speaker reflects that commitment, with clean design, purposeful engineering, and a drive to deliver exceptional sound that lasts.

BENCHMARK PERFORMANCE

CUSTOM DRIVERS

Every 1723 speaker features a custom-built driver for power and precision. The 8-inch mid-bass units deliver fast response, low distortion, and deep, articulate bass. Tuned for a wide frequency range, they preserve clarity and weight across music and film.

WAVEGUIDE TWEETER

A precision 28mm soft-dome tweeter and custom waveguide ensure wide, consistent dispersion — keeping the soundstage focused, wherever you sit. Instruments feel three-dimensional. Vocals stay anchored. Highs remain smooth, detailed, and perfectly blended with the midrange.

HDF CABINETS

Every 1723 speaker is built from thick, reinforced HDF — denser and more inert than MDF. It reduces resonance, tightens bass, and delivers cleaner sound. Larger cabinets add damping layers to kill remaining vibrations. It’s the kind of quality you can’t always see — but you’ll definitely hear it.

PREMIUM CROSSOVER 

Built with premium parts and 24dB/octave slopes, each crossover is tuned through careful listening and precise measurement. The result? Seamless integration, natural balance, and effortless performance — on and off-axis.

BASS PORTS 

Tower and Monitor models offer tuneable ports for flexible bass control. Seal them for tighter response, or open for deeper impact. Tune your setup to your space and taste — no trade-offs required.

READY FOR
SERIOUS BASS?

A great speaker system deserves a subwoofer that can keep up. The 1723 Series subwoofers are built with the same precision and purpose as the rest of the lineup — delivering deep, powerful, and controlled low-end that completes the experience. Whether you’re after room-shaking impact or tight, musical precision, there’s a 1723 subwoofer that fits the bill.


Not sure where to start? We break it down by room size, listening style, and performance goals — so you can find the right match for your setup.

LOOKING FOR SOMETHING
MORE COMPACT?

If the full-size 1723 Series is more than your room (or budget) needs, the 1723 Series S offers a more compact alternative — with many of the same components, engineering principles, and sonic character. You’ll find the same level of detail, dynamics, and build quality — just in a more compact form.

WHAT THX ULTRA REALLY MEANS

THX Ultra is more than just a badge — it’s a performance standard designed for serious home theaters. Certification ensures your speakers meet strict requirements for clarity, low distortion, wide dynamic range, and consistent sound coverage across large rooms. It means every whisper and explosion is heard just as the creator intended — even at reference volume.

To pass, a speaker must achieve balanced frequency response, tight directivity, and seamless tonal matching across the system. It’s a guarantee of sound that meets the highest standard. But the 1723 Series goes even further, blending THX-certified impact with the finesse and transparency audiophiles demand.

Here’s the twist — we didn’t design the 1723 Series to pass THX certification. We designed it to perform. THX Ultra certification came later, with no changes needed. That means you get all the benefits of reference-grade cinema sound, plus the musicality and finesse that make these speakers just as extraordinary in a two-channel setup.
