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.

Professional reviews

  • “The subwoofer is a lot of fun, especially in terms of precision and speed.”

  • Their sheer solidity, together with their elegant industrial design, raises them to luxury-class products.

  • “High-end sound and more of a high-end experience.”

  • It’s a subwoofer that manages to sound really big and powerful but on the other hand also takes on a much more subtle role as part of the sound system.

  • The control is great, the dynamics impressive, the weight and power are actually pretty awesome, and it impresses both for its size and its price.

  • Arendal Sound continues to impress, and Subwoofer 1S is not an exception. With very flexible adjustability and impressive control, this subwoofer belongs in both hi-fi setups as well as the home cinema.
