SOUNDBOKS Launches New Speaker with Merus Audio eximo® Amplifier Technology; Now Shipping

The Loudest Battery-Powered Speaker Just Got Even Better

Herlev, Denmark, August 28, 2017 – Copenhagen, Denmark-based SOUNDBOKS ( recently released a follow-up version of their popular party speaker, known among music festival participants and other party goers as “The loudest battery-powered speaker.” High performance, long battery life, and rugged good looks are what make the new SOUNDBOKS 2 stand out from the crowd. Among other improvements, the updated version features two Merus Audio MA12070P amplifier ICs and is now available.

“After a very successful initial product launch, our intended primary design for SOUNDBOKS 2 was to make the new product even louder, while delivering better audio performance and extending its battery life,” explained Ruben Bjerregaard, SOUNDBOKS lead engineer. “This sounded like an impossible quest, but the all-digital amplifier and patented eximo® Class D switching amplifier technology from Merus Audio has helped us to realize this reality. The SOUNDBOKS 2 is now rated at 122db SPL. It is optimized both for indoor and outdoor use, and battery life is now extended to 40 hours.”

Weighing in at just 33lbs. (15kg),  SOUNDBOKS 2 is driven by two 10-inch (Ø 254mm) professional woofers and a single 1-inch (Ø 25mm) state-of-the-art neodymium silk dome tweeter. The result is a universal speaker with frequencies all the way down to 40Hz and the crystal clear highs of 20kHz.

“The combination of our advanced multilevel switching topology and built-in dynamic power management really pushes the boundaries of efficiency,” said Martin Helms, Merus Audio director, global sales. “We are extremely pleased that the guys from SOUNDBOKS were able to put this to good use with their new product. At the same time, the durability requirements from SOUNDBOKS put our technology to the test. If your product can survive a week at the Roskilde festival playing full blast under all weather conditions it can pretty much withstand anything. We feel that being selected by SOUNDBOKS is both an important endorsement and a valuable quality stamp for us.”
