Questions and answers

Which is better for movies?
The Klipsch RP-1400SW. Its 14-inch driver and 1,000 W amp give more output and deeper bass for explosions and soundtracks, and it connects to any AV receiver.
Can the Sonos Sub Gen 4 work with a regular receiver?
No. It connects over Wi-Fi only and needs the Sonos app and Sonos speakers. There is no RCA input.
Which is easier to set up?
The Sonos. You pair it in the app and run Trueplay. The Klipsch needs a wired RCA cable from a receiver's subwoofer output.
Which takes up less space?
The Sonos. Its compact cabinet fits under or beside furniture. The Klipsch is 20 in wide and 25.67 in deep.
Is the Klipsch worth it over the Sonos?
If you have a receiver and want maximum bass output per dollar, yes. If you are building a Sonos system, the Sonos is the only one of the two that fits.
