The 804 D4 is the most compact floor standing speaker in the 800 Series Diamond range. Its new reverse-wrap cabinet follows the proven design principles established by its larger siblings and its new plinth ensures rock-solid, accurate bass response. Cabinet stiffness has been increased with an Aluminium Plate that reinforces the top of the cabinet. Midrange performance has been dramatically improved with a new Biomemetic Suspension that replaces a conventional fabric spider with a groundbreaking innovation that reduces distortion behind the drive unit. The Solid Body Tweeter enclosure has been elongated, increasing air volume behind the diamond tweeter which improves the openness in high frequencies. The top section’s aluminium top-plate is covered in Leather by Connolly trim. We use luxurious, full-grain black leather for Gloss Black and Satin Rosenut finishes, and a light grey leather for White and Satin Walnut. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is our benchmark and the most advanced range of loudspeakers we know how to make, equipped with our most sophisticated technologies and designed to deliver the upmost in sonic realism. The 800 Series Diamond is everything we know, and everything we are.

This is a great speaker if you want a floor standing speaker in the 800 series. It too also has the new suspension of the line. Just note the cabinet and the ise of copper instead of solver capa you will be missing out on. Still a recommended speaker
