Sonodyne Sonus 3155 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 90dB** — each 3 dB more sensitivity needs roughly half the amplifier power for the same loudness. This is an efficient speaker for most AV receivers.
• **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 60Hz ~ 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 3155:

• Front left and right channels in a 5.1 or 7.1 home theatre
• Stereo music listening without a subwoofer in many rooms
• Medium to large living rooms and dedicated rooms

When Another Option May Suit Better

You may prefer a different configuration if the room is small or the speakers can't be pulled away from the wall — a bookshelf pair or on-wall speakers with a subwoofer may suit better.

What Else You Need for a Working System

A passive speaker: it needs an AV receiver or stereo amplifier. For films, add a matching centre, surrounds and a subwoofer. Final matching should be checked by an audio consultant against your room and equipment.

• Sonodyne Sonus 3165 — 3 way vented, floor-standing speaker
• Sonodyne Sonus 3260 — 2 way, vented, bookshelf speaker
• Sonodyne Sonus 3360 — 2 way, mtm, vented, centre speaker
• Sonodyne Sonus 3350 — 2 way, mtm, vented, centre speaker
• Choose a matching AV receiver — Denon, Marantz and Onkyo models with full specifications

Room and Installation Guidance

What we check when installing this product:

• Keep the pair equally spaced from side walls and away from corners
• Toe the speakers in slightly towards the main seat
• Leave space behind for the port and cables
• Set speaker size and crossover in the AV receiver during calibration
