Super tweeters for soaring highs 

Experience pristine highs, whether it’s music or dialogue.

Carbon Fibre diaphragm for rigid speaker construction

A carbon fibre diaphragm ensures each speaker can reproduce sound with minimal distortion across the entire frequency range. The rigid, stiff properties of carbon fibre make it an extremely strong material – which is ideal for driver unit cones. This allows air to move at low frequencies without distortion for sound reproduction that’s clear and detailed.

Magnetic fluid speakers: high power, small size

By eliminating conventional speaker dampers and replacing them with magnetic fluid speaker technology, the size of the speaker is significantly reduced without affecting its accuracy and detail. Originally developed for NASA, magnetic fluid technology means you can fit great-sounding speakers in a smaller space – ideal for thin televisions and other compact, premium speakers.
