The 804S is a more compact version of the 803S. Exactly the same midrange and tweeter configuration is used, but bass is supplied by two smaller 165mm (6.5 in) diameter Rohacell® cone drivers. These operate into a smaller, narrower Matrix-braced cabinet, making this model ideal for the medium size listening room elegant and unobtrusive.

Many of the features that go to making the 800 Series models so exceptional are hidden away inside the system. Silver coating the magnet pole in the tweeter helps extend its high-end response. The midrange driver utilises a powerful Neodymium-Iron-Boron magnet. It supplies enough strength to energise a long magnetic field that remains constant over the voice coil's full movement, ensuring the incredibly low levels of harmonic distortion necessary to reproduce programme with full clarity to high output levels.

Our crossovers use only air-cored inductors, again for lowest distortion, and capacitors developed and optimised in conjunction with one of the world's foremost manufacturers. And all contacts are gold plated, to ensure long-term freedom from corrosion.
