This is an excellent addition to my Sonos set-up (Beam Gen 2 and 2x Ones as rears) In honesty, there is about enough Bass from the Beam and One's but at times it lacks a little depending on the content watched (plentiful for Dolby Digital content but lacks sometimes on music/non-Dolby content) after watching the SHS video review on the sub-mini and taking advantage of the 30-day money back guarantee trial I thought what do I have to lose? and honestly it's an amazing addition! It gives a new level of bass, has a real punch to it and does free up the other speakers to do more. E.g. I have had to now turn down the surrounds and the speech enhancement on the Beam as now it is just not needed. We have the sub on around 0 and the Bass on 3, beforehand the Bass was on 9-10 so that's just how much difference this sub makes!
