Bowers & Wilkins · 800 Series Diamond
The 800 Series D4, as Bowers makes room for what is next.
New in box, full warranty, the reference flagship. Trade your current pair toward it and we will put a real number next to your name. No pressure, no script.
The flagship, at the changeover.
Bowers is clearing the D4 for the next generation. That makes this a narrow window. The current reference 800, new in box, while the changeover lasts. The new line opens well above where the D4 sits today. So if you have been circling the 800, this is the moment the math gets friendly. The speaker does not get worse because a newer one arrives. Same diamond tweeter, same engineering, same speaker people drive across the state to hear.
