Duo Northside Hi-Fi Brisbane Queensland Australia

The DUO combines all of Avantgarde's technological and creative potential, resulting in a highly advanced horn speaker. With its larger and more efficient midrange horn, this system offers unrivaled performance across the sound spectrum. and is already a "classic" among horn systems. This is due to its efficiency of 103 dB, and the homogenous sound quality of this system. Those who have heard the fortissimo of an orchestral recording, the sound of a human voice, or the natural faithfulness of a solo instrument played on this system, will know what we mean.  

Technical Overview

 The DUO includes a two-way Hornspeaker satellite, provided with the integrated active sub-woofer SUB225 CTRL PRO (making it a 3-way system).

The M2 midrange driver was specially designed for the DUO. The huge magnetic structure of the 7-inch cone provides an efficiency of 103 dB (1W/1m) as well as offering very high power handling. The resonance characteristic of its 4-inch dome is optimized by a special coating at the backside of the dome. The design of the dome ensures the sound-waves entering the midrange horn SH 6704 are in phase and cover the required bandwidth. The CDC system features a controlled roll-off at 2,000 Hz and allows the use of a phase-correct passive frequency crossover. Typically for Avantgarde, the M2 operates into the low frequencies without any degrading components in the signal path.

The H2 tweeter is a reduced sensitivity version of our reference TRIO tweeter H3. The exceptional driver H2 combines the smoothness of an electrostatic driver and the power of a strong 1-inch horn driver. The mere force of the 6.5 lb. magnet on the voice coil guarantees 100% detail and precision even at low volume levels, and provides the DUO with compression-free sound reproduction even at extreme sound pressure levels.

The H2, with its spherical horn, offers an ultra wide bandwidth down to 900 Hz. With the passive crossover point a full octave higher at 2,000 Hz, you get a wonderful smooth sound with incredible musical headroom.
