The Model 50/Jamaica Active Speaker System


"The NSMT Model 50/Jamaica active tower speaker system is a pretty unique offering in the high-end speaker world, giving you a well matched speaker/amplifier system with the amplifer built in to the speaker cabinet." (hometheaterhifi)


The NSMT Model 50/Jamaica active is a passive Model 50 with a built-in full-featured amplifier that can be activated with a flip of a switch. It is passive or active!

  • Some comments from the first review:

  • "Listening was a joy.
    In all cases , I was pleased with the sonics of the system.

  • I felt the bass was clean, with clear non distorted output down to at least 40Hz.

  • The built in amplifers certainly allowed  robust loud playback without strain or distortion."


  • The Active Model 50 AKA Jamaica speaker is a standard Model 50/Jamaica except that it has a built-in full featured amplifier. The Model 50/Jamaica is active and passive because the built-in amplifier can be  disconnected with the flip of a switch which allows you to use an external amplifier of your choice.


    The Active Model 50/Jamaica achieves stunning performance because we use two eight inch shallow high power paper cone woofers and a recessed one inch wave guide soft dome tweeter in a MTM arrangement that is time coherent and wired to simulate a point source in our proprietary DTL 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 100 dBs, the Jamaica speaker system can easily be driven to loudness of about 105 dBs with as little as 5 watts RMS at a distance of about 8 feet from the speakers. With 1 watt you can drive the Jamaica speaker system to about 102 dBs at about 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. Read more about the Model 50 here.
