Professional reviews

Every time we test Norwegian products, we are accused of being overly positive, but could it simply be that the products made here are so well thought out and proper that they deserve all the praise they get?


Very well designed speakers, with a premium finish that is noticeable right out of the box. They offer a neutral and transparent sound, with magnificent dynamics and perfect integration.


Terrific choice for those who don’t wish to sacrifice fidelity even at very high drive levels, so if you like the idea of the subwoofer keeping its composure in all circumstances, the 1961s are well worth consideration. 


It tells me that someone at the company, most likely the owner, just cares a lot about the product.

Nemo Propaganda

Arendal continues to deliver interesting home cinema products, but they play music just as impressively. Even if the speakers in this case are very compact there is still a lot of, and cool sound to hear.

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.

CEA 2010

CEA-2010 is measured at 2m distance, following current guidelines. CEA-2010 measurements should be presented in 1m Peak measurements currently, although many are still using 2m RMS, so we include these as well.

Please note that our vented design is extremely difficult to accurately measure as the port and driver are on different planes. We are suffering some output on CEA-2010 measurements for this reason.

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.
FCC mark is a voluntary mark employed on electronic products manufactured or sold in the United States which indicates that the electromagnetic radiation from the device is below the limits specified by the Federal Communications Commission and the manufacturer has followed the requirements of the Supplier's Declaration of Conformity authorization procedures.
