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
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.
HeimkinoWhen 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

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.
