Hello
I haven’t found any real world responses in the community regarding using dual Sonos subs. That said here is my take on the subject. I’m not going to provide information on how to properly position Sonos dual subs as I believe Peter Pee does an excellent job of explaining how to get the best listening experience. You can listen to his recommendations on the subject at this link .
Basic components: Arc, Beam, Playbar, Playbase or Sonos Amp bonded to a Sonos Gen3 sub and then adding a second Sonos Gen2 or Gen3. For ease of setup assuming you have a Sonos Gen2 sub already I recommend removing it, add the Sonos Gen 3 and re-add the Gen2.
Straight away let me say that using dual subs is AWESOME. IMO what you should expect is not a lot of increased volume. What you will get is a more immersive experience. Using a single sub I heard the rumble of an explosion...now I FEEL it to a much greater degree.
The subs are at 90 degrees to my Arc spaced 12 feet apart (inside measurement) along the left wall when seated. My room 12.5ft (width) x 19.5ft (length) x 8ft (height). All wall surfaces are smooth with a minimalist textured ceiling. The complete setup consists of Arc / Sub x 2 / Sonos One x 2.
I’d love to hear from other members who are using dual subs.
Cheers!
Note: Dual subs may not be the best choice for everyone. In fact using dual subs could make your listening experience worse as detailed in the above review link by Peter Pee.
