  • The Model 50/Jamaica Active Tower speaker system is a remote controlled wireless music system that delivers the reference-quality sound of our highly received Model 50/Jamaica passive tower. It uses the same elegant, compact 42 by 9.5 by 8.5 inch (H X W X D) cabinet and provides the same acoustical performance as the Model 50/Jamaica.


    Featuring a built-in 60 watt, Class D amplifier with high-quality wireless Wi-Fi and AptX Bluetooth as well as wired RCA, 3.5mm, and optical digital wired inputs and a subwoofer output (LFE), the Model 50/Jamaica Active music system offers a compelling choice of almost limitless use possibilities for music and theater lovers.


    The Model 50/Jamaica Active speaker system is a two-way, time coherent simulated point source design that uses our proprietary short dual transmission line (DTL) cabinet technology to provide powerful bass performance limiting the need for a subwoofer. The elegant two-toned cabinet with wood side panels provides a non-distracting black front profile if the speakers are used in a theater system.


    The Model 50/Jamaica Active system is designed to play all genres including, Dub Reggae, Rock, Classical. It can be used in both large and small listening rooms. It excels in audiophile two channel stereo systems as well as in multi-channel and two channel theater systems, even without a subwoofer. When used as a passive speaker system, it can be driven by any amplifier from a one watt SET amplifier to the most powerful solid state amplifier. 

  • Two-way speakers are some of the most magical speakers, because of their tonal and timbral accuracy, and because of their imaging and accurate spatial presentation. However they tend to lack low bass response and when they do achieve good bass response it comes at the expense of efficiency and the ability to play loud.


    We transcend these limitations by using a modified highly efficient soft dome tweeter, hi-power, high sensitivity 8 inch broad band paper cone woofers in a series, crossover-less implementation, in our DTL cabinet design. These choices facilitate our design principle of avoiding the use of crossovers in the fundamental frequencies range of most musical instruments and voices and allow us to "crossover" the tweeter with a passive second order crossover at 5,500 Hz, well above the fundamental frequencies of most instruments and voices. 


  • Using crossovers in the fundamental frequency range of instruments and voices tends to cause phase anomalies that degrade sound reproduction. Not using crossovers limits the ability to shape bass response, power handling and distortion. Our DTL transmission line cabinet design approach to bass reproduction allows the Model 50/Jamaica Active to produce powerful bass without distortion even at high volume because of reduced cone movement that is a characteristic of transmission line design. Using this design with a passive tweeter crossover is crucial for allowing the Model 50/Jamaica Active system to be used as a passive pair of speakers. 


  • As a result of our design approach, the Model 50/Jamaica Active is a versatile compact speaker system that checks all the boxes necessary for reference quality audiophile sound. It has all the magic of the classical two-way minimonitor with almost limitless dynamic headroom and potent articulate bass.
