The previous NSM (NSMT) Model 50 was highly regarded. In his 1995 review of the Model 50, Julian Hirsch of Stereo Review had this to say:
"The NSM Model 50, despite its conventional appearance, is not just another conventional column loudspeaker. The goal of its designers was to produce a "compact acoustic suspension system with the bass response of a subwoofer, and the imaging and soundstaging of a minimonitor."
The Model 50's measured sensitivity was 85 dB, exactly as rated. The room response above a few hundred Hertz was very uniform and smooth, with a variation of only +2.5 dB from 300 Hz to 20 kHz.
Even at 32 Hz, the output was only 6 or 7 dB below the average midrange level, and (as listening confirmed) it was perfectly audible and usable at that frequency.
The Model 50's group delay (an indicator of its phase linearity) was among the lowest and most uniform we have measured to date, with a peak-to-peak variation of less than 0.2 millisecond from a few hundred Hertz to 20 kHz.
All of this suggests that the NSM Model 50 is a very good speaker, which had been apparent from our first listening. How did it sound? For one thing, it was unobtrusive, in the sense that we were never particularly aware that the sound was emanating from those black boxes, even when quite close to one of the speakers.
I suspect that the NSM speakers were the more "accurate" of the two (whatever that may mean), and that its spatial performance was more realistic. I like sonically-unobtrusive speakers that do not call attention to themselves yet give a believable impression of a concert-hall performance. By those criteria, the NSM Model 50 is a great success. Hear it for yourself if you can."
When we ceased production of the Model 50 in 1998 its price was $1,795, which is equivalent to $2,785 today. Today we are introducing a worthy successor to the original Model 50 at $1,795.
