EVO4.S Surround Speaker
Sold Out
The EVO4.S is a dedicated surround speaker for EVO4 home cinema systems — a three-way sealed-box design engineered for an enveloping rear soundfield. A 165 mm (6.5") woven Kevlar bass driver works alongside twin 50 mm (2") soft-dome midranges and twin 30 × 60 mm AMT tweeters.
Its closed-box enclosure gives tight, controlled output, while the dual-midrange, dual-AMT array — with crossovers at 1.5 kHz and 4.4 kHz — spreads surround effects wide for a seamless, diffuse rear image across a 70 Hz – 22 kHz response and a 106 dB peak SPL. At 88 dB sensitivity and 8 Ω (3.9 Ω minimum), it suits amplifiers from 25 to 120 W.
It completes an EVO4 cinema alongside the EVO4.C centre and the EVO4 towers — see the full EVO4 Series and our home cinema range.
Wharfedale Australia is the official, AVR-authorised distributor — every EVO4.S is backed by genuine Australian warranty and local support.
