Sonos is still the leader when it comes to wireless, multi-room audio systems. With a dead-easy setup routine, well-designed controller apps, and the ability to play music from both your local stash of MP3s and all the big streaming services, the palindromic home audio supplier is playing with a winning hand.
Now Sonos has released a subwoofer to complement its array of wireless Play speakers and Connect amps. It’s simply called Sub. The $700 powered speaker component isn’t cheap (none of the Sonos stuff is) but it does add excellent definition and low-end heft to any existing Sonos system.
The Sub’s glossy, piano-black case is shaped like a big, square doughnut with a rectangular hole in the center. That central cavity is where all the sound is directed. Two 4.5-inch by 7-inch rectangular divers, each with its own class-D amp, face each other from opposing sides of the cavity. The speaker enclosures are ported into the cavity, too, with one port at the top and one at the bottom.
