TRIO Northside Hi-Fi Brisbane Queensland Australia

The TRIO includes a three-way Hornspeaker satellite, which is provided with a pair of integrated active SUB225 CTRL PRO sub-woofers per channel, operating from 18-100Hz (making it a 4-way system).

The specially optimized midrange driver L3 is characterized by its extremely high efficiency of 107 dB (1W/1m) and utmost power handling capabilities. Due to our CDC system, the L3 is just the same as our other hornspeaker systems, it works exclusively within its optimal frequency range and automatically rolls-off at the crossover frequencies (100-600Hz).

Connected to the midrange horn SH9504, the L3 offers a very neutral sound reproduction across the entire mid-bass range. Vocals, instruments and complex signals are reproduced with so much speed and ease, you'll forget that you are listening to a recording.

M3, our midrange driver system, is the core of the TRIO and was especially designed for our spherical horn SH5702. The 2-inch driver system, covering a frequency range between 600-4,000 Hz, will amaze you with its high sensitivity, very low distortion and an excellent linear response. The M3 system features a very large magnet structure that offers high power handling and long linear excursion of the diaphragm.    

In contrast to the typical compression driver, the M3 uses a special dispersion characteristic with a very low compression ratio. The energy which is needed for the lower frequency range is provided by a strong and linear movement of the voice coil and not by a high compression ratio. It is this special design that makes a major contribution to the crystal clear transparency of the midrange frequencies even at extremely high power levels.

Instead of a 2-way system with an additional super-tweeter, the TRIO actually is a real 3-way-satellite-system. The L3 midrange-bass driver works exclusively up to 600 Hz; thereby eliminating the critical "break-up" of the cone as well as distortions that are typical of the upper frequency range of a cone driver. The tweeter H3 starts working at 4 kHz, thus avoiding the problems of excessive membrane movement. Therefore, the H3 is optimized for the high frequencies, instead of being misused for the midrange. The result is a harmonically accurate system with 3 drivers working exclusively in their own well defined frequency range.

H3 is our statement for the TRIO high frequency range. The H3 features a voice coil former made of Kapton with a minimized air gap. A special geometrical shape of the voice coil and an ultralight diaphragm makes this special driver really outstanding. Its high magnetic flux density helps to produce enormous power and authority on the movement of the voice coil. The H3 convinces by its lively ability to reproduce the shimmering musical detail and tremendous dynamics of any kind of music.
