Uno Northside Hi-Fi Brisbane Queensland Australia

If you're considering entry into the world of the spherical hornspeaker, the UNO is just right. The UNO can be placed even in small rooms. It offers what a normal loudspeaker does not have 100% emotion. With an efficiency rating of 100 dB, the UNO is a rocket among conventional loudspeaker systems! This amount of high efficiency and high dynamics means more musical detail, and most importantly, lots more fun.

Technical Overview

The UNO includes a two-way Hornspeaker satellite, provided with the integrated active sub-woofer SUB217BR PRO (making it a 3-way system). Optionally, it can be ordered with the SUB225 CTRL PRO (the standard DUO and TRIO Subwoofer).

The M1 is a 4-inch midrange driver with a 2.5-inch dome especially developed for this system. The design of the dome ensures a phase-neutral radiation of the sound waves into the midrange horn SH 5702 and ultra-wide bandwidth of the extended midrange. The large, linear movement of the M1 allows a very low cut-off frequency. To its low end the M1 runs without being slowed-down in full-range operation, e.g. is not limited by any passive frequency filters. The CDC (Controlled Dispersion Characteristic) system features a controlled roll-off at 3,500 Hz and allows the use of a phase-correct passive frequency crossover.

H1 is a high-frequency tweeter providing an extremely wide frequency range capable of reaching down to 1 kHz. Based upon the same design principle of the nearly "legendary" TRIO tweeter H3, the H1 offers very low distortion and excellent transient characteristics. The over-dimensioned magnet structure of the tweeter, weighing 6.5 lbs., results in a sound pressure level of 100 dB (1Watt/1m), yet specified at a very high power rating (over 100 watts).
