Copenhagen, Denmark-based SOUNDBOKS recently released a follow-up version of its party speaker, hailed by the company as “the loudest battery-powered speaker.” 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,” said 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 33 pounds (15kg), SOUNDBOKS 2 is driven by two 10-inch (254mm) professional woofers and a single 1-inch (25mm) neodymium silk dome tweeter. The result is frequencies down to 40Hz and 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.”
Merus Audio creates amplifier solutions designed to maximize output power and audio performance and design freedom for applications in the professional/consumer portable, home theater, and automotive audiovideo markets. eximo is based on a patented multilevel audio amplification technique that provides a higher resolution output with high efficiency and exceptional audio quality.
