The Centre-Plug replaces the traditional dust cap, making the cone both lighter and more responsive, while also cooling the voice-coil resulting in higher power handling and a stable sound reproduction when playing loud. The design produces increased power-handling capabilities along with a more uniform, precise and dynamic reproduction of sound.
The Centre-Plug also prevents potential break-up points where the dust cap would have been glued to the cone. In addition, it prevents over- and under-pressure behind the dust cap when the cone moves back and forth. The advantage is more dynamic and precise sound reproduction.

This unique feature minimizes one of the major barriers to good sound reproduction. To avoid boomy bass reproduction, loudspeakers must normally be placed well away from the wall – often impractical in many living rooms.When a woofer fires downwards it couples with the floor, making placement less critical. In other words, this speaker can be placed close to the wall.
 

The HCC technology (Hard Conical Cone) enables the driver to reach far beyond midrange frequencies before any significant cone break-ups occur. The material’s rigidity and the cone’s conical shape ensures the unit creates clear and detailed sound with very little distortion, even at high sound pressures. This combines with the natural rubber suspension, which effectively prevents vibrations from travelling back to the diaphragm; the result is a very well-controlled diaphragm that operates vwithout break-ups up to 4kHz -well beyond its working range.

WaveGuide is the unique way Jamo has shaped the tweeter’s faceplate. The result is a controlled sound pattern with a more open and dynamic reproduction of sound. WaveGuide makes it easier to position the speakers in the room.
Another big challenge is to secure a uniform dispersion pattern in the treble and midrange frequencies. In general, the dispersion is getting narrower as the frequencies get higher. Consequently in the area where the mid/woofer and the tweeter should integrate smoothly, the mid/woofer has a narrow dispersion and the tweeter has a wide dispersion. This problem is solved with the Jamo WaveGuide. The completely smooth design of the WaveGuide also reduces diffractions to an absolute minimum. Finally, the WaveGuide increases treble output in the lower treble range, which means the tweeter needs less power for the same SPL. So, power handling is improved and distortion is reduced.
