Shopping for the perfect monitors is a complicated process that's unlike buying any other professional audio gear. One sizable challenge is deciding which system type will integrate best into a particular (or in a variety of) work environments. What is “required” is a proverbial can of worms in itself, encompassing personal taste, consideration of the personal tastes of others — i.e., clients — and a litany of other factors, both aural and monetary. Unfortunately, the task of auditioning monitors too often occurs in environments that are dissimilar to the spaces in which they will actually be used. After all of this — and dealing with a few issues overlooked here — the best pair of monitors for a particular scenario can hopefully be found. If you're considering a multichannel monitoring setup, get ready to consider a host of variables.

To address the fact that even the most accomplished audio pros sometimes teeter at the edge of sanity before buying a new multichannel monitoring system, many manufacturers now offer complete surround packages at one price point. Most of these systems include familiar models, while other packages are designed from scratch as a set. As price points vary dramatically from package to package, you'd be hard-pressed not to find something that comfortably fits both your needs and budget.

Not all studio monitor manufacturers are represented in this article. While reasons vary as to why some don't offer all-in-one packages, many companies that opt out feel that multichannel configurations are best built via individually selected components. Nevertheless, many engineers have successfully met their multichannel listening needs — and eliminated a few headaches — by purchasing one of the innovative surround packages listed here.

The Alesis (www.alesis.com) ProActive 5.1 ($499) is an affordable, THX-approved 5.1 system. While it won't hold an aural candle to high-end systems costing thousands of dollars, it offers plenty of features, satisfactory sound and much value for a low amount of dough. The 450-watt ProActive 5.1 system includes four 65W satellite monitors with a 69W center speaker, a 188W powered subwoofer and the Digital SoundTouch Control Center with wireless remote. The SoundTouch controller has a LCD status screen and offers built-in Dolby Digital and DTS hardware decoding, gain control and much more. On the rear of the unit, source inputs include digital optical, digital coaxial, 6-channel analog direct inputs and a stereo analog input.

Known for its unique transmission line (TL) monitoring systems, British manufacturer PMC (www.pmcloudspeaker.com) offers the PMC Mix Pack ($7,995), a fully matched, active 5.1 kit featuring five PMC DB-1A loudspeakers and a SubTLE1 subwoofer. TL technology effectively creates a long tunnel within a monitor by using internal partitioning. The tunnel folds throughout the length of a heavily dampened cabinet, and at the tunnel's end, a hole vents into the room. As a result, the cabinet yields an extended LF range and dramatically reduces any extraneous coloration of the sound. According to PMC, the DB-1A loudspeaker is the world's smallest TL monitor design with an effective line length of five feet within its very small cabinet. The 100W DB-1A features a 5.5-inch low-frequency driver, an aluminum, ferrofluid-cooled HF driver, and a frequency response of 5 Hz to 25 kHz (+0/-3 dB). The SubTLE1 Subwoofer includes two 6.5-inch shielded custom drivers driven by a 150W low-distortion amplifier. The subwoofer incorporates an effective TL of 9.5 feet, allowing the TLE1 to produce a flat frequency response down to 22 Hz.
