Floorstanding loudspeakers — Avalon Acoustics Iris Signature

The Iris Signature is a floorstanding loudspeaker from the American manufacturer Avalon Acoustics. It draws on technology first used in the company's Tesseract and Saga designs.

Key specs that matter

Avalon rates the response from 20 Hz to 100 kHz within plus or minus 3 dB, reaching far beyond the limit of human hearing. Sensitivity is 90 dB, nominal impedance is 4 ohms, and Avalon lists a recommended amplifier range of 50 to 500 W. Each speaker measures 152 x 37 x 43 cm and weighs 80 kg.

Engineering and use context

Avalon's engineers do not optimise each parameter in isolation. Power, amplitude, phase and transient behaviour are handled together as one integrated set of design targets.

Pairing

That wide power window covers both integrated amplifiers and powerful separates, although the 4 ohm load favours amplification that delivers ample current.

Alternatives

Avalon Acoustics' PM3.2 is a smaller floorstander from the Precision Monitor series.
