Excellent deep sub bass that cannot be achieved with the beam or play 5 speakers alone. With the sub paired with the speakers. It really opens up the speakers as all bass duties is now sent to the sub and the beam and play 5 opens up its midrange dynamics. Literally night and day.
Now I cannot be without the sub as you literally lose some detail without it from the speakers.
Need to buy a few more for each room.
And the inward firing sub woofer means no vibration! Wow! Most of my old subs resonate like crazy at high levels, you actually hear some ringing from the windows and Woofer case but not the sonos. You only hear the bass from the music.
