The Model 50 AKA Jamaica is a two-way, time coherent, double transmission line system that reproduces music with excellent clarity, musicality, spatial presentation, dynamics, and speed.

 

The lasting impression one gets from visiting Jamaica is the sheer prevalence of music. In terms of the quantity and quality of music produced by Jamaicans, as Shaggy and Sting attest, Jamaica a country of roughly three million people, punches way above its size. Drive into a small town and chances are you car will be rocked by bass dominant Reggae or Dancehall music emanating from large speakers somewhere in the square.

 

While we can't replicate the sheer power and grandeur of those large speakers we wanted to produce a compact, affordable, powerful, audiophile speaker with incredible dynamics that much like Jamaica punches above its size in performance and value and can replace much larger speakers.

 

To accomplish this we use two eight inch paper cone woofers and a one inch soft dome tweeter in a MTM arrangement that is time coherent and wired to simulate a point source in a double transmission line cabinet design.

 

The woofers are implemented crossover-less to cover the fundamental frequency of instruments and voices from 35 Hz to 4,750 Hz. Without a crossover there are no phase anomalies that tend to muck up the sound in this frequency range. The woofers are seamlessly integrated with the tweeter which handles harmonics above 4,750 Hz. The tweeter is implemented with a 12 dB crossover to protect it at extremely high volume levels.

 

These design choices allow our Jamaica speaker to deliver stunning dynamic performance and much like Jamaica to punch above its size in performance and value. 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.

 

With a sensitivity of 101 dBs, the Jamaica speaker system can easily be driven to loudness above 106 dBs with as little as 5 watts RMS at a distance of 8 feet from the speakers. With 1 watt you can drive the Jamaica speaker system to 102 dBs at 6 feet from the speakers. 

 

The Jamaica speaker system proves there is no longer a need for monstrous speakers to get live sound pressure levels. 

 

Being thankful for the inspiration, we dedicate our Model 50 Jamaica speaker to all the musicians and singers and people of Jamaica.

Heritage

NSMT-old-Model50

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.
