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?
Stereo+1961 Subwoofer 1S
Lack for nothing on the low notes
Tighter. Sharper. Deeper. And more dynamic. Yes, you can have all your bass in one sleek, sealed, smaller-sized casket. For smooth detailed hi-fi sound, and a low end that lacks for nothing.

Compact. Yet insane performance.
Market-leading bass with its unique driver design from the 12.2″ woofer. The magnetic grill makes it easy to show off the high driver excursion.

Smart amplification
Full 550W real power down to 10Hz with market-leading technology and functions. A new statement. Avalanche 550 IQ.

Extensive connections
No more problems connecting AV-Receiver and stereo amplifier at the same time. 550 IQ manages this elegantly.

12.2" High excursion driver
Premium performance.

Hi-res display
When we add tens of features, we need extensive yet simple and intuitive controls. All displayed on the hi-res LCD display.

The Puck
Customized resonance-free feet installed.
Professional reviews
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.
AVPasiónTerrific 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.
AudioholicsIt tells me that someone at the company, most likely the owner, just cares a lot about the product.

Technical specifications
EQ2 26-200Hz (+/-3dB)

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.
