All rooms have certain frequencies that are both amplified and reduced based upon the dimension of the room and where the subwoofer is placed in the room. If you want to understand this concept better, simply put on some music with repetitive deep bass, and walk around your room — including both the middle and against the walls. You’ll find some spots where the bass is really loud and others where you can barely hear it. If you move your subwoofer, those positions will change. When you add a second subwoofer, most of those peaks and dips get canceled out by the second sub — especially, if you put it in a different area of the room. This is why we feel — for the best home theater experience — you’ll be so much happier with two subwoofers.

When Sonos told us they were finally going to give us the ability to add a second subwoofer to a Sonos system, we were thrilled and could not wait to test it out. We do have to mention, if you are adding a second Sonos Sub to your system, one of the subwoofers will need to be the new Gen 3 version that was recently released. However, since it was not possible to add one before, any new one you buy should be a Gen 3 — but it would be wise to confirm that is so before you purchase your second one.

After getting the second sub added to the Arc with Sonos One SL’s for surrounds, we could not wait to test it out. It turned out, in our room, the difference it made was huge! The first clip we tried was from the latest Midway film during the bombing of Pearl Harbor. With one subwoofer, there was plenty of bass, but the bass definition and effortlessness of all the special effects just took a big jump up in audio quality. Explosions had far more impact with much better definition. We then moved to a Netflix series called Inhuman Resources that had been on our list. There is a scene in one of the episodes where there is an upright acoustic bass in the soundtrack. This one was even more impressive as to the difference with one versus two than the explosions in Midway. The difference in the tonal quality of the bass with two was just astounding. You could hear the body of the bass resonating far better with just one sub.

In summary, our experience with adding a second Sonos Sub to a Sonos home theater system is exactly what we have experienced many times in the past. In almost any system, two subwoofers are going to give you a big improvement in sound. It is not just the fact that you have more bass. The whole system just becomes more effortless sounding with a far better definition of the lower tones.
