Monitor Audio SB4 Passive Soundbar
$1,749AUD inc. GST
The Monitor Audio SB4 is a high‑performance passive LCR soundbar engineered to complement large‑format televisions while delivering the clarity, precision, and dynamic capability expected from a true hi‑fi loudspeaker. Designed for screens 70 inches and larger, the SB4 provides a visually balanced, acoustically refined front‑stage solution ideal for premium media rooms and home‑theatre installations.
Inside its robust, acoustically inert cabinet, the SB4 houses three independent speaker channels—Left, Centre, and Right—each built with Monitor Audio’s advanced driver technology. The soundbar features C‑CAM bass/midrange drivers paired with C‑CAM Gold Dome tweeters, delivering crisp high‑frequency detail, articulate dialogue, and a wide, immersive soundstage. Its internally braced MDF construction minimizes resonance, ensuring clean, accurate performance even at higher listening levels.
The SB4’s design emphasizes both performance and installation flexibility. Its low‑profile binding posts, recessed terminal panel, and compatibility with SANUS TV mounting systems make integration straightforward and clean. The cabinet’s wrap‑around acoustically transparent cloth finish and brushed aluminium end trims give it a discreet, elegant appearance that blends seamlessly with modern displays.
As a passive soundbar, the SB4 requires an external AV receiver or amplifier, allowing it to scale with higher‑quality electronics and outperform typical powered soundbars. It can be paired with a subwoofer for deeper bass extension or used on its own for a significant uplift in TV audio clarity and presence.
The Monitor Audio SB4 is built for homeowners and installers who demand both aesthetic refinement and uncompromising audio performance. With its premium materials, thoughtful engineering, and lifetime‑warranty build quality, it stands as a sophisticated solution for enhancing large‑screen entertainment systems.
