SOUND DESIGN – TOP JAMO TECHNOLOGIES

It’s not only by listening to the market that Jamo found its success. From the earliest days Jacobsen aimed to get ahead through innovation in acoustic technologies, and key early ideas emerging from the shores of the Limfjord included the CBR-system, the integrated pushpull subwoofer (IPPS), Linear Loading, and Controlled Dispersion treble units (see the WaveGuide below). Some of the long-lasting Jamo innovations include:

Decoupled Tweeter technology (DTT, pictured above): a mounting system developed and patented by Jamo to reduce the effects of cabinet vibration on the tweeter’s own performance.

The centre plug:

an alternative to the traditional dust cap, cooling the voice-coil and lightening the cone, thereby increasing both precision and power handling.

Hard Conical Cone technology (HCC):

a combination of rigidity and shape which keeps the cone’s break-up modes far above the midrange band, so improving clarity within the driver’s operating range.

WaveGuide:

the higher the frequency, the narrower the dispersion of sound, so tweeters tend to ‘beam’ more tightly than mid/woofers, and off-axis listeners can experience poor integration between the two, especially around the crossover frequency. Jamo’s WaveGuide is shaped to reduce this, while also reducing diffraction and the power required to drive the tweeter. The macro effect is to make speaker positioning far less critical.
