No consumer format in the history of audio has succeeded so quickly as DVD, which offers attractive functions and features such as 5.1 surround sound, interactive menus, and bonus tracks in a format that’s ideal for both home and portable applications. Consumers are upgrading to multichannel home sound in record numbers.

Today, record labels and movie studios — both majors and independents — know that there’s a large, appreciative audience looking for new product, which is good news for audio pros. With the production of new releases and mastering/remixing yesterday’s hits (music or cinema), the surround floodgates are wide open and getting wider.

One of the key ingredients in upgrading your studio for surround production is a quality monitoring system, and we queried more than 30 loudspeaker manufacturers about their top-of-the-line surround systems. Each company listed here offers its best system for recording, editing and mixing in surround, whether that’s a custom-designed system and/or a packaged surround setup. Most of the companies also offer downsized systems for smaller rooms and project facilities — and manufacturers’ contacts are provided so that you can explore further on your own — but for the purposes of this article, we wanted to examine their ultimate systems.
