Conclusion

Home multichannel audio is no longer the territory of the enthusiast and as such consumer multichannel audio systems are evolving to meet the demands of the non-audiophile, non-enthusiast users.

Producing surround sound from fewer speakers inevitably requires some compromise in the sound quality and will necessarily be somewhat room dependent. Further compromises may also be found in cost and the region of the room in which the best sound may be experienced.

A number of different & ingenious approaches have been devised to solve the problem. Each approach has merits and areas of compromise. DSP, psychoacoustics and special transducer arrays all play a part in these solutions.

The resulting products extend the range of performance/cost/ergonomic compromises to the end user allowing more people than ever to enjoy surround sound in their homes.
