ALBEDO - ITALY Achema vs Bowers & Wilkins 801 D4
Bowers & Wilkins 801 D4 vs ALBEDO - ITALY Achema pits two dynamic passive floorstanding speakers with very different design philosophies against each other. The 801 D4 is a large 3-way vented-box reference tower with a diamond dome tweeter, Continuum cone FST midrange and twin 250mm Aerofoil bass units, weighing roughly 100kg per speaker; reviewers at SoundStage Solo and HiFi News praised its deep, controlled bass, natural midrange, refined treble and expansive, dynamic presentation, while noting it demands powerful amplification and generous room space. The Achema is a slim 2.5-way transmission-line tower using ceramic drivers (7" woofer, 6" midrange, 1" tweeter), a Mundorf-based crossover and Albedo's Helmholine resonator system, with a quoted 44–22,000 Hz response, 85dB sensitivity and 11-ohm load. This comparison helps weigh scale, bass extension and amplification needs against room-friendly size, with the caveat that detailed review scoring is available only for the 801 D4.
