1723 Bookshelf S THX

Latest member of the 1723 family

The Bookshelf S as the smallest and latest member of the 1723 family. Featuring a completely custom built 2-way lineup of mid-bass driver and a waveguide tweeter you cannot find anywhere else. The materials, quality, drivers and crossover components are the same premium level as you would only expect from any of the 1723 family members. Bigger is not always better.

HI-END CONNECTIONS

Rhodium-plated copper terminals. The aluminum backplate is precisely recessed for a perfect fit in the HDF cabinet.

PREMIUM COMPONENTS

High-performance tweeter in an elegant and highly accurate waveguide backed up by our custom 6.5″ driver.

THE PREMIUM FEEL

Magnetically fastened steel grills, wrapped in premium cloth for a smooth look. A “thump” and the grill is snapped onto the gorgeous HDF cabinet in premium paint.

Professional reviews

HiFi Test

Arendal Sound Bookshelf S is one impressively playful, lively, competent and engaging compact speaker!

Stereo+

The 5.1 system of Arendal delights us in our test with outstanding musicality and a highly dynamical ability despite of the compact format.

Heimkino

When we start playing some music, I am not surprised that these speakers have some very good all-round characteristics. On the other hand, I am quite surprised of how much I enjoyed classical music on them

Rognliens Hifi

Incredibly good work down there in the Southern part of Norway - it should not be easy to match the price tag, the great quality feeling and the amazing sound of the Arendal Sound 1723 Bookshelf S THX Ultra

ENCLOSURE TUNING

Vented vs. Sealed – Whatever floats your boat!

CROSSOVER NETWORK

Crossover design is a culmination of model, measure, listen, remodel, remeasure, re-listen, all while refining performance in increasingly small steps.

MAGNETIC METAL GRILLS

We are especially proud of our new exclusive and fully custom made grills. For all Arendal Sound speakers we have made a free flowing, perforated metal grill which does not affect sound quality.

MASSIVE & CLEAN BASS

The 6.5” woofers in the 1723 S THX series are built upon the same core fundamentals as the the 13.8” subwoofer, but with application specific details changed.

WAVEGUIDE TWEETER

The heart of all Arendal speakers, our Tweeter utilizes a 28mm synthetic soft dome with custom designed, matching waveguide.

SPEAKER INPUT POSTS

Chosen for its excellent conductivity, corrosion resistance and hardness; all serve to protect the copper material and music signal carried within.

THX Certified

All our 1723 speakers are Certified by the very strict testing protocols of THX Ultra where each speaker must pass a set of 400 measurements. The THX Certification does not mean it is a dedicated home speaker, but rather a guarantee of tight consistency within well-established acoustic parameters. THX Certification is as much about music, as for movies.

The engineers at THX Labs utilize a proprietary scientific testing methodology to ensure the highest audio fidelity possible. All 1723 speakers passed the THX Ultra Certification without any change to the products, meaning our standards already exceed THX Ultra level out of the box!

Frequency response

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 response

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.

Impedance response

The impedance charts are electrical measurements of the loudspeaker’s resistance vs frequency.

Product compliance

CE marking is an administrative marking with which the manufacturer or importer affirms its conformity with European health, safety, and environmental protection standards for products sold within the European Economic Area (EEA).

RoHS is an abbreviation for “Restriction of (the use of certain) Hazardous Substances in electrical and electronic Equipment”. This directive restricts the use of ten hazardous materials in the manufacture of various types of electronic and electrical equipment. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of huge amounts of toxic electronic waste.
