Welcome to our Definitive Technology - Dymension DW MAX SUR In-Wall Speaker Review. If you’re chasing immersive, room-filling surround sound that truly disappears into your décor, the DW-MAX SUR sets a new benchmark in in-wall audio innovation. In this review, we’ll explore how its bipolar array, BDSS™ woofers and Linear Response Waveguide™ combine to deliver a home theatre experience worthy of the most discerning audiophiles.

Design & Installation

The DW-MAX SUR boasts a flush, border-free design with a paintable micro-perforated magnetic grille that seamlessly integrates into any wall surface. Pre-construction brackets and a toolless, two-piece mounting system with pivoting “dog” arms mean you can install each speaker in minutes—no drills or fuss required. Whether you’re retrofitting a media room or building new, the IP55-rated enclosure also makes it ideal for high-humidity spaces or covered outdoor theatres.

Advanced Acoustic Engine

At the heart of the DW-MAX SUR are dual 6.5" mineral-filled BDSS™ woofers with Linear Response Waveguide™. This patented driver architecture provides improved excursion, output and midrange uniformity—giving you punchy, articulate bass and transparent vocals. The bipolar array places two woofers and two aluminium oxide dome tweeters on opposite-faced horizontal planes, energising the room with a wider sweet spot and enveloping soundstage that traditional in-wall speakers simply can’t match.

Customisable Highs & Cohesive Timbral Matching

A three-position tweeter attenuation switch (–2 dB, flat, +2 dB) lets you fine-tune high-frequency output to suit room acoustics—bright tiles or plush carpets, you decide. And for those building a complete home cinema, the DW-MAX SUR is timbre-matched with other Dymension CI and Mythos models plus Descend Series subwoofers for a seamlessly integrated system from front to back.

Performance Highlights

• Expansive Sweet Spot: Bipolar design creates a broad, immersive sound field ideal for large seating areas.
• Crystal-Clear Highs: Pivoting 1" aluminium oxide dome tweeter delivers pin-point imaging and distortion-free clarity.
• Effortless Bass: BDSS woofers combined with Linear Response Waveguide™ for deep, controlled low end down to 34 Hz (–10 dB).
• Weather-Resistant: IP55 rating means reliable performance in bathrooms, alfresco lounges and poolside pavilions.
