Sonodyne DE 4340 Specifications

What the Specifications Mean in Practice

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

• **Built-in or rated power: 200 watt into 4Ω per channel, 100 watt into 8Ω per channel** — check this against the speakers' recommended amplifier power.
• **Frequency response 20Hz ~ 20kHz, ± 3dB** — 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 DE 4340:

• Extra amplification for in-wall and in-ceiling speakers
• Powering extra surround or height channels
• Background music zones

When Another Option May Suit Better

You may prefer a different configuration if you only need a standard 5.1 or 7.1 system — a single AV receiver may be enough.

What Else You Need for a Working System

Needs a preamp, processor or AV receiver with pre-outs, plus passive speakers. Final matching should be checked by an audio consultant against your room and equipment.

• Sonodyne DE 4380 — 8 channel power amplifier
• Sonodyne IWO 912 — 2 way, bass-reflex on-wall/in-wall speaker
• Sonodyne SIC 3460 — 2 way in-ceiling speaker with magnetic grille

Room and Installation Guidance

What we check when installing this product:

• Allow ventilation around the amplifier
• Plan rack or table-top placement
• Use balanced cables where the source supports it
