1723 Center S THX

Downscaled version of the 1723 Center

The 1723 Center S is a downscaled version of the 1723 Center. The speaker is identical to 1723 Monitor S, but sold singly and with the grill badge moved for aesthetic purposes. This makes sure that you will have 100% timbral match when using it with any of the 1723 speakers like the Monitor S and Tower S which are sharing the exact same core MTM design. The materials, quality, drivers and crossover components are just the same as you would expect from any of the 1723 speakers. The only difference is smaller enclosure with 6.5” drivers in 1723 Center S, instead of the 8” in the 1723 Center. The sheer performance, level of detail and dynamics delivered by Center S is unheard of in this price category. Expect the Center S to be compared to much higher priced center speakers on the market.

Professional reviews

Is it any good? The answer is yes. A resounding yes. In fact it is the best speaker in my current setup.”

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.
