Subwoofers are like the magic beans of audio, expanding a playback system's dynamic range in a way that dramatically enhances the listening experience. There's an attitude among some audiophiles that subwoofers represent, if not the spawn of the devil (there are numerous such spawns in audio lore), a bad compromise at minimum. But the truth is that adding a modest but well-designed subwoofer to speakers, even compact bookshelf models, can result in better performance than what you'd get from full-range towers that cost considerably more.
I’m in the interesting position of telling you how to do something with a subwoofer that you shouldn’t do. No, it’s not illegal. But in the ears of those for whom sound quality is more important than ergonomics, décor, and/or domestic tranquility, it’s definitely heretical.
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.
Q I just bought Polk Audio Monitor 40 Series II speakers and want to know how to install them using bi-wiring. Do I connect two separate wires from the positive and negative outputs on the receiver and run them to the separate positive and negative input sets on the speaker? What benefits will that provide? —Kris Green, via email
