odeon audio Helix vs Bowers & Wilkins 801 D4
The Bowers & Wilkins 801 D4 vs odeon audio Helix pits two very different dynamic passive floorstanding speakers against each other. The 801 D4 is a 3-way vented-box reference design with a diamond dome tweeter, Continuum cone FST midrange and twin 250mm Aerofoil bass units, rated at 90dB sensitivity, 8Ω (minimum 3.0Ω) and a 50W–1000W recommended power window; reviewers from HiFi News and SoundStage Solo praise its deep, controlled bass, natural midrange, refined treble, expansive imaging and effortless large-scale dynamics, while noting its 100kg mass and need for powerful, high-quality amplification. The odeon audio Helix is a three-way horn design specified at 94dB sensitivity, 8 Ohms, 30Hz–26kHz and 51kg, with crossover points at 450Hz/2.600Hz; its assessment is specification-led, as no listening reviews were available. This comparison helps you weigh evidence-backed reference performance against a more efficient, horn-based alternative suited to lower-power and tube amplifiers.
