Compact Line Arrays for Installation

It’s not uncommon to see the same sound reinforcement gear found on major tours used in large churches and other fixed installations where great sound is paramount. But the high-end goods, especially loudspeakers, are not only too big to hang in some venues, but they also bring more power than you’d need to cover a small space. Manufacturers have answered the call for higher-end speaker solutions for use in clubs, small houses of worship, hotels, corporate event centers by scaling down larger rigs to more manageable sizes and prices. This month’s feature is an A to Z roundup of compact line arrays with woofers that measure 9 inches or less that are currently shipping. Please visit the companies’ websites for more information and additional product options.
