Abstract
A loudspeaker suitable for the generation of surround-sound effects comprising a plurality of transducers that are together arranged to generate one or more beams of sound, at least one of which beams is steerable, wherein the transducers are arranged to reproduce sound only at frequencies higher than a selected lower frequency limit of 250 Hz or more. The loudspeaker may be foldable or dismantable so as to allow greater portability and may have means for interacting with an external electronics device, for example to allow low frequency sound signals to be reproduced by woofers in the external device.
