For listeners who crave the performance of an 800 Series Diamond tower speaker but prefer a more conventional aesthetic, the 804 D4 is the perfect choice. Its new cabinet and plinth make it our best-performing 804 yet.
Classic quality
804 D4 is perhaps more conventional in appearance than other tower speakers in the 800 Series Diamond range, but it’s every bit as sophisticated. Its new Reverse-Wrap cabinet is both a mechanical and acoustic revolution in its class, and its new plinth ensures rock-solid, accurate bass response too.
Aluminum top-plate
Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet with an all-new aluminum top-plate. This also provides a perfect mounting point for all-new Leather by Connolly trim, with luxurious black leather for dark cabinets and light grey for lighter finishes.
Reverse Wrap cabinet
Instead of a conventional loudspeaker box, the cabinet in 804 D4 is made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound.
Aluminum plinth
A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport exiting on to a solid aluminum plinth complete with a steel constrained layer damping sheet, which controls unwanted resonance. It also has greatly upgraded spikes for maximum stability and durability.
