It is accurate even when measured at 2.5 feet, and it is also health friendly and Eco-friendly, which makes it suitable for nearfield listening, gaming, home theater, recording studios, concert halls, discos, churches, and schools.

Can a health friendly and environmentally friendly compact loudspeaker be suitable for nearfield audiophile listening, gaming, home theater, studio monitor, concert halls, discos, churches, schools? The Chorus can play all these venues because of its unusual combination of finesse and power.

The Chorus like all NSMT loudspeakers is designed for the holy grail of audiophile listening. It is minimum phase, time coherent, positive polarity to preserve waveform, with no crossover to the woofer and a 12 dB per octave crossover to the tweeter. It can can be driven by any amplifier from a single-ended triode to a 600 watt solid state. And it has the finesse and power to play anywhere from a den to a auditorium. It has a humongous wide and deep soundstage, a spectacular midrange, images on par or better than some of the best minimonitors, it reproduces vocals beautifully, and projects sound with the authority that makes every recording sound live. It can play any venue from a den to an auditorium.

The NSMT Chorus Active speaker employs a built-in 60-watt amplifier (30 watts RMS per channel) with Wi-Fi and Bluetooth connectivity. The Chorus' amplifier is a feature-packed full range Class D amplifier with high-quality Wi-Fi and AptX Bluetooth input. In addition to its wireless inputs, the amplifier features RCA, 3.5mm, and optical digital inputs, plus a subwoofer output (LFE).

With a sensitivity of 96 dBs, the Chorus can easily be driven to loudness above 100 dBs with as little as 5 watts RMS. Therefore 30 watts RMS provides the Chorus with an almost limitless dynamic headroom.
