Bowers & Wilkins 702 S3 Signature
The Bowers & Wilkins 805 D4 and Bowers & Wilkins 702 S3 Signature are premium audiophile speakers designed for very different listening needs. The 805 D4 is a compact stand-mount speaker from the flagship 800 Series Diamond lineup, featuring a Diamond Dome tweeter and exceptional detail retrieval. In contrast, the 702 S3 Signature is a larger floor-standing tower speaker with a dedicated midrange driver and multiple bass drivers for greater scale, deeper bass, and room-filling performance. If you're choosing between precision-focused listening and full-range high-impact sound, these two speakers represent distinct approaches to high-end home audio.
Verdict
The Bowers & Wilkins 702 S3 Signature is the stronger all-around choice for most buyers thanks to its three-way design, higher sensitivity, deeper bass extension, and greater power handling. It delivers a bigger, more immersive soundstage that suits larger rooms and home theater setups. The 805 D4 remains an outstanding option for dedicated audiophiles seeking reference-level detail, imaging, and premium compact speaker performance in smaller listening spaces.
