The preference in loudspeaker product design is for small size, while preserving maximum low frequency extensionand output volume. If the goal is to create a realistic reproduction of a live event, then certain speaker parametersmust be adequately controlled, such as volume displacement, intermodulation distortion, stored energy and off-axisfrequency response. Components must be carefully selected for low distortion performance. Parameters like phaselinearity and cabinet diffraction are sometimes overrated. Multi-channel speaker setups require propagation delaycorrection and bass management, if not all speakers cover the full frequency range. These issues are reviewed at theadvent of high resolution surround sound. The new technology can only fulfill its promise and expand into morethan a niche market, if capable loudspeakers are widely available.
