1723 Series
Controlled, predictable performance independently designed and validated to meet THX Ultra reference standards.

No compromise whatsoever.
FOR MUSIC AND MOVIES
The 1723 THX Series is the culmination of years of design, analysis, testing, and listening. 1723 THX is the Arendal Sound statement of intent to deliver a quality of design, materials, and fidelity at prices the market has hardly seen. There are no corners cut in material specification, whether you can see them or not.
In the Premium segment of speakers, where others disguise steel with gold, we use rhodium-plated copper. Where others use plastics, we use machined aluminum. Where others skimp on cabinet thickness, we went thicker and then up-spec’d to high-density fibreboard panels (HDF).
We did all of this because it delivers better audible results.
1723 Series offers THX Ultra certified speakers in 6.5″ (1723 S THX) and 8″ (1723 THX) versions, and our newly designed 13.8″ 1723 subwoofers with impeccable value for the money.
Our HDF cabinets, thick crossover PCBs, and ancillary parts, feature engineering detail you will not find at anything like the price. You will find no plastic parts, even if we could have used them to keep costs down without affecting sound quality.

CERTIFIED BY THX
1723 speakers are Certified by the very strict testing protocols of THX Ultra
where each speaker must pass a set of 400 measurements.
It is a guarantee of tight consistency within well-established acoustic parameters.
Unparalleled Customer benefits
These benefits reflect our commitment to you, ensuring maximum security, peace of mind, and an exceptional customer experience every step of the way.





PREMIUM
BUILD QUALITY
Higher density and naturally stiffer than MDF. Using HDF (High-Density Fiberboard) results in a sonically inert cabinet. We use no plastic parts.
