Amazon's been a busy bee these past few weeks. Not only has it put out a brand new Amazon Echo, the smart-home focussed Echo Plus, revealed the screen-packing Echo Spot and launched a new waterproof Kindle Oasis, it's also been quietly working on some software audio tweaks for its new speakers, too.

The latest update, quietly pushed over the air this past weekend, focusses on the audio performance of the new standard Amazon Echo. And it's all about that bass.
