Floorstanding loudspeakers — Avantgarde Acoustic ZERO iTRON

The Zero iTRON is an active floorstanding loudspeaker from Avantgarde Acoustic, built with an exceptionally high sensitivity and substantial internal amplification. Avantgarde Acoustic is a German manufacturer with a distinctive reputation for large-horn loudspeaker engineering, and the Zero iTRON represents an active expression of that broader house philosophy.

Position in line

It sits alongside the UNO SD and Opus 1 in Avantgarde Acoustic's range as related designs. This positioning alongside the UNO SD and Opus 1 suggests Avantgarde Acoustic offers several distinct product lines exploring horn loading at different scales, with the Zero iTRON representing the brand's active, internally amplified approach.

Key specs that matter

Rated response is 18 Hz to 22 kHz. Sensitivity is an extraordinary 107 dB, among the highest figures available in any domestic loudspeaker. Internal amplification totals 10+10+400 W across the tri-amplified design. At 49.0 x 109.0 x 40.0 cm and 40.5 kg it is a substantial, moderately weighted tower given its considerable amplification and driver complement.

Sound and use context

Expect an extraordinarily dynamic, effortless presentation given the exceptional 107 dB sensitivity, with the internal amplification matched precisely to each driver band - Avantgarde Acoustic's horn-loaded design philosophy at this sensitivity level delivers a different listening experience from any conventional direct-radiating speaker, characterised by an almost live-sound immediacy at any volume.

Pairing

As an active design, no external power amplifier is used - a preamplifier or direct source connection feeds the built-in amplification, simplifying the signal chain considerably despite the horn-loaded design's typically demanding scale.

Alternatives

Avantgarde Acoustic distinctive horn-loaded aesthetic, instantly recognisable within the industry, means this model visual presence in a room is as much a consideration as its acoustic performance for many buyers.
