The process of buying studio monitors has never been an easy one. Choosing from a plethora of products in a dealer’s showroom can be difficult enough, but these days, monitors come in every conceivable size, design style, type and price — ranging from compact near-fields to gargantuan ultra-SPL main systems. Users must also decide between various options such as powered and unpowered models, analog or digital inputs, stereo pair or 5.1 array, dedicated center-channel models, subwoofers, bass-management features, and even remote and network-control functions.
The “old standard” monitors that were so popular 10 years ago won’t necessarily cut it in today’s production environment, especially with the growing need to work in high-resolution analog and high-bit rate 96/192kHz digital formats for surround and stereo mixing. To help you sort out what’s available, we decided to check out some recent entries in the monitor market, focusing on models that have debuted during the past year, listed alphabetically, with Websites provided for more information.
Available in both powered and unpowered versions, the ADAM Audio (www.adam-audio.de) S2.5s and SV4s are designed for stereo and multichannel applications. The S2.5 includes an 8-inch woofer and an A.R.T. (Accelerated Ribbon Transducer) HF driver and handles 120 watts RMS. The powered version of the S2.5, the S2.5-A, drives each component with separate 100W amps. S2.5 frequency response is 38 to 35k Hz, and the S2.5-A dips lower to 24 Hz. The larger three-way SV4 and SV4-A add an A.R.T. midrange and an 11-inch woofer. The SV4 handles 150 watts of program power; the SV4-A has three separate 100W amps. The SV4 has a stated response of 32 to 35k Hz, and the powered SV4-A brings the bottom end down to 28 Hz.
British speaker manufacturer ATC re-enters the U.S. project studio market with its T-16 ($3,000/pair) monitor. These active monitors were designed with modern music production in mind and are tailored to the sound of rock, hip hop and dance music. The T-16 houses a 6.5-inch mid-bass driver and a 1-inch tweeter in a ported enclosure. All power is derived from the internal amplifier, which delivers 200 watts to the woofer and 50 watts to the tweeter. The T-16 also includes controls for variable sensitivity and bass boost. ATC is distributed by Transamerica Audio Group, www.transaudiogroup.com.
Bag End’s (www.bagend.com) INFRAsub-18 PRO and INFRAsub-12 PRO models offer new features for pro studio surround monitoring, such as six balanced XLR inputs and five highpass-filtered, balanced XLR outs.
