This sub perfectly integrates with every sonos' speaker you use it with. Amazingly non invasive and clean, it can act both as a musical and a home theather sub, simply by adjusting its level by the app.
The gen1 and gen2 are identical, they differ just for the logo, the internal O color and the new white color.
We tried several subs, even the new acoustic mass 300 by the wannabe-sonos brand of Bose, and it simply isn't on the level of the sonos' one, even if this is way older.
If you have a playbar it defintely gives you the another-level sound you could expect. The trueplay is a must too
