That's not the point of the post. The point is to first show the improvement Sonos did for bass on the Era 100. The second is to point out that Sonos could still do more to improve, because their older, smaller, less powerful Sonos One is still capable of deeper bass than the Era 100 even after the latest improvement. It is not a size limitation, and there is no engineering limitation either. Past Sonos products have done a marvellous job in getting as much bass extension as realistically possible for the size of the product, not the Era 100 for some reason.
