These waste sound waves move back into the speaker box and then bounce around off the angular surfaces, causing reverberation and distortion. Sound engineers have long known that rounded, sloping surfaces like funnels quickly cancel out distortion. However, the lower the sound frequency the longer the funnel needs to be. That s where the giant Nautilus speaker comes in. It s spiralling, carbon fibre shape effectively absorbs unwanted vibrations and it has an improved, aluminium diaphragm to produce less waste in the first place.
Shorter tubes do the same job for the higher frequency speakers.
