Speaker Setup

Patrice Congard, founder and CEO of U.K.-based Screen Audio Excellence, discusses subwoofer placement and the potential pitfalls of phase cancellation in the latest installment of an ongoing tech series, published here with his permission.

Dolby Atmos, for you members of the unwashed and uninformed masses (yeah, you know who you are), enables film sound designers to treat individual sonic elements as virtual “objects” that can be placed and moved almost anywhere within the three-dimensional space of a movie theater. Two things are important about its adaptation for home theater. First, the soundfield—in its original, discretely encoded version, not an extrapolated one—is no longer limited to a two-dimensional plane circling around your ears.

If you’re reasonably handy and not afraid to cut into drywall in your home, installing in-wall speakers can be a fairly simple affair. You’ll need to assemble the basic tools, including a drywall saw, a stud finder, an electrical snake or fiberglass push rods to run the wires, a tape measure, a drill with a long bit wide enough to pass your speaker wire, and a screwdriver, most typically a No. 2 Phillips.

Selecting audio components is one of the more daunting tasks that any serious home theater enthusiast faces. On the surface, it seems evident that if you just go out and buy the best components you can afford, they’ll sound great with both movies and music. And that’s generally true: A better system will more accurately reproduce the waveforms you feed it, irrespective of whether they come from a movie or music. But it’s often not that simple. While assembling a home theater system that’s equally spectacular with movies and music may be a laudable goal, unless you have unlimited funds, you’ll probably have compromises to make. At that point, you might want to steer the system’s performance strengths one way or the other with the right mix of speakers and electronics. But how do you go about matching these up?

Optimizing your sound, one step at a time.

Getting all the pieces for that new system into your room is just the first step to home theater bliss. You’ll need to set up the A/V receiver’s inputs, position the speakers, and configure the AVR’s speaker adjustments for balanced sound before you get to movie time. I’ll frequently refer to your AVR, but the steps will be identical for a separates system with a surround processor and power amp.

Tips and tricks for making your system tweakin’ awesome.

Unless you have really expensive tastes, it’s easy to see how spending several thousand dollars on your home theater system can make some very noticeable improvements. That kind of cash could buy a bigger TV, a larger projection screen, a brighter projector, a beefier amp, or a stouter subwoofer. Any of these would put some extra kick in an already kick-butt system. But maybe—like me—you don’t have piles of cash sitting around begging to be stuffed into a store’s cash register. Perhaps you just bought your first HTIB, recently added to your existing system, or (again, like me) you’re simply a classic cheapskate. Whichever it is, let’s say you’ve maxed out your A/V budget for the year. Now what?

When you get that new speaker set you're going to need to configure and balance your system. The process described below describes AVRs, but both the features and steps you'll take are identical if you're using a "separates" system with a pre-amp/processor and power amp.
