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

PREMIUM
BUILD QUALITY

BUY DIRECT from
ARENDAL SOUND
Buying direct removes uncertainty — about pricing, advice, and long-term ownership.
By selling without distributors or retail layers, we stay accountable for the entire experience: how our products are built, how they’re explained, and how they’re supported over time.
No Hidden Margins
By removing distributors and retail markups, pricing reflects the product itself — with more of your budget going into engineering, materials, and quality control instead of sales layers.
Advice Without Sales Pressure
With no dealers, quotas, or commissions, guidance is based on your room, listening habits, and system goals, by specialists — not on what needs to be sold.
Proven Where It Matters: At Home
Because sound depends on the room, evaluation happens in your own space, with a 60-day home audition, free returns (USA & EU mainland), and support during setup.
Support That Extends Beyond the Sale
Selling direct creates a long-term responsibility, backed by consistent platform design, spare parts availability, and a 10-year warranty.
Direct-to-consumer isn’t about shortcuts.
It’s about clarity, accountability, and long-term confidence.
