The NSMT Model 25/Chorus Active


"... the Chorus Loudspeakers really beat my Maggies in terms of stereo image."
(Mel Martin,

"...NSMT now offers the best active Bluetooth/wireless speaker system. Far superior to all the rest."
(customer, California)

"... the KEF LS-50 speakers...($1500 per pair) ...were bested by the Chorus."

Price per pair: $1,495
Combining power and finesse

(Shown: satin black)


Comments from Mel Martin's review of the active version of the previous Chorus:

"I really wasn’t quite prepared for the excellent performance of these speakers, in particular the palpable 3D stereo image that the Chorus speakers created in my listening rooms. Imaging is the ‘holy grail’ of speaker design, and NSMT has achieved this elusive capability just right."

"... the Chorus Loudspeakers really beat my Maggies in terms of stereo image."

"... the KEF LS-50 speakers...($1500 per pair) ...were bested by the Chorus Loudspeakers in terms of depth and instrument placement."

"With a rated sensitivity of 96 dBs (now 98 dBs), the speakers could easily be driven to 100db, something I confirmed with an SPL meter. The speaker specifications say a user can reach that volume with only 5 watts from the included amplifiers, and my experience bears that out."

"At just under $1200 with integrated amps, the NSMT Chorus powered wireless speakers are an outstanding value."

(Mel Martin, 


The NSMT Model 25/Chorus Active speaker provides the same performance as the standard Model 25/Chorus but it employs a built-in 60-watt amplifier (30 watts RMS per channel) with Wi-Fi and Bluetooth connectivity to provide the utmost flexibility.

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 wired 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. 


Sensitivity: 98 dB Tweeter and woofer both connected in positive polarity (preserves absolute polarity from microphone to loudspeaker)

Time coherent, minimum phase design

Crossover-less woofer, second-order crossover to tweeter.

8 inch painted paper cone woofer 1 inch soft dome tweeter

Rated impedance: 8 ohms Minimum impedance: 4.5 ohms

Multi-strand OFC copper wire to woofer and tweeter 

All Chorus loudspeakers are outfitted on the back panel with 1/4-20 threaded retainers that are spaced four inches apart to facilitate attachment to optional custom floor stands, optional metal telescoping stands, articulating tilting and swivel TV wall mounts, and custom "Hangman ASM6-2" wall brackets.
