Engineers worked to pack performance into a compact package with the immersiveDSP SPK-4P cube speaker, which integrates eximo multilevel-technology from Merus Audio. Suited for both commercial as well as multiroom residential AV applications, the SPK-4P has an MSRP of $395 USD.

“The SPK-4P is a PoE+ full-range loudspeaker that combines network audio streaming, Class D amplification, and Digital Signal Processor (DSP),” said Tony Rouget, CEO miniDSP. “A single Cat-5/6 network cable provides power, low latency audio, and control for a plug-and-play experience. Multi-Level switching eximo audio amplifier technology developed by Merus Audio provides 2x15W for powering two speakers (local and height), thus making each SPK-4P effectively an amplifier for two speakers (master and slave).”

Denmark-based Merus Audio is a creator of audio amplifier solutions that maximize output power and audio performance and design freedom for applications in the home theater, portable, automotive, and professional audio/video markets.

“eximo is the world’s most advanced switching amplifier technology, enabling the smallest possible amplifier solutions for slim and compact audio products for home and commercial applications,” said Martin Helms, Merus audio director, global sales. “The combination of a multilevel switching topology and a dynamic power management scheme pushes the boundaries of efficiency and the compactness of audio amplifier solutions. It is the ideal solution for the immersiveDSP SPK-4P cube speaker.”

The SPK-4P, which utilizes a 4-inch full-range driver, also consists of Audio Video Bridging (AVB) technology powered by a 500MHz XMOS processor to provide low latency, uncompressed, and tightly synchronized streams to each speaker over standard networks. The onboard 400MHz Analog Devices SHARC processor also enables signal processing for true high-resolution audio capability and equalization, crossover, and room-correction capabilities. 

“The low power losses of eximo also ensures the longest battery lifetime for portable products, also making it the ideal amplifier technology for modern home and outdoor commercial audio products,” Helms said. “In the world of portable audio, eximo multilevel technology enables more powerful sound combined with the lowest power consumption and the smallest footprint for battery-powered audio devices.”
