Floorstanding loudspeakers — Avantgarde Acoustic DUO GT

The DUO GT is a legendary horn-loaded floorstanding loudspeaker from Avantgarde Acoustic, a well-established German manufacturer known for uncompromising horn-driver engineering, built with a staggering sensitivity and a distinctive built-in bass amplifier. The DUO GT brings Avantgarde's most storied horn-loaded engineering heritage to a substantial floorstanding format.

Key specs that matter

Rated response spans an exceptionally wide 18Hz to 28,000Hz within plus-or-minus 3dB. Sensitivity is a staggering 107dB into a distinctive 18 ohm load - an extraordinary figure among the highest efficiency figures available in any commercial loudspeaker, reflecting Avantgarde's celebrated horn-loaded heritage. Recommended external amplifier power is a modest 10W for the horn-loaded midrange and treble sections, with a substantial 1,000W built-in bass amplifier handling deep bass reproduction. At 173.2 x 67 x 69.6cm and 108.5kg, the DUO GT represents a serious commitment reflecting Avantgarde's legendary horn-loaded engineering heritage.

Sound and use context

Expect the immediate, dynamically alive character Avantgarde's legendary horn-loaded driver technology is broadly celebrated for, with the staggering 107dB sensitivity meaning the midrange and treble horns reach satisfying volumes readily from even the most minimal amplifier power, while the substantial 1,000W built-in bass amplifier handles deep bass directly.

Pairing

The modest 10W external amplifier requirement for the horn sections makes the DUO GT compatible with even the most minimal single-ended triode amplifiers, while the built-in bass amplifier handles low-frequency reproduction directly.

Alternatives

Avantgarde's own DUO SD offers a related model with a somewhat different internal amplifier configuration within the same broader catalogue.
