So far the system is incredible. I was trying to choose between a Play 5 pair, or a single Play 5 with a SUB and I do NOT regret my decision to get the SUB.
I have an open floor plan in my home and wanted something to fill the space with rich sound. Several threads said that a stereo pair of Play 5s would be the way to go... but I've tried a few speakers in my space and none of them really had the "depth" that I was looking for. The Sonos SUB fills my desire perfectly! It's so rich. I may eventually get that second Play 5 to really fill the space, but I have no regrets. :D
I noticed a few topics saying that Trueplay really scaled back the SUB, and while I agree that Trueplay did make the sound a bit 'lean'... what it did beautifully was balance the sound in my space and eliminate boomy "hotspots". All I did was bump up the bass a bit in the EQ and also bumped up the SUB level a touch to fill the room.
