Sonodyne Sonus 3440 Specifications

Values copied from Sonodyne's official product page, checked on 16 October 2026. Where Sonodyne doesn't publish a figure, we leave it out rather than estimate. View the official Sonodyne page.

What the Specifications Mean in Practice

Our notes on reading these numbers — LiveInSmart guidance, not manufacturer claims.

• **Sensitivity 86dB** — each 3 dB more sensitivity needs roughly half the amplifier power for the same loudness. Allow amplifier headroom in larger rooms.
• **Nominal impedance 8Ω** — an 8-ohm load is easy for almost any AV receiver or amplifier.
• **Recommended amplifier power 60 ~ 125 watt** — a range published by Sonodyne, not a requirement to buy the largest amplifier. Room size and listening level decide what you need.
• **Frequency response 75Hz ~ 20kHz (-3dB) on axis** — the low figure shows how much bass the product produces before a subwoofer is needed.
• A specification does not guarantee a listening result — room size, furnishings, placement and calibration change what you hear.

Who Should Consider It

Typical uses for the Sonus 3440:

• Side or rear surround channels in 5.1 and 7.1 systems
• Height channels where the manufacturer lists the model for that use

When Another Option May Suit Better

You may prefer a different configuration if your room is better served by in-ceiling or in-wall surrounds that stay out of sight.

What Else You Need for a Working System

A passive speaker that needs AV receiver or amplifier channels. Final matching should be checked by an audio consultant against your room and equipment.
