Short answer: the Brane X for the higher ranking, the Marshall Stockwell 2 for the lower price. The Brane X ranks #4 of 75 large speakers at $500. The Marshall Stockwell 2 ranks #11 at $200, $300 cheaper.
The case for the Brane X: Very deep bass, the absolute deepest from this category. Set against that: Boosted upper bass ~120hz, rolled off treble, so it’s missing detail up top.
What the Marshall Stockwell 2 gets right: Possibly the most natural sounding Marshall speaker. Set against that: Not stereo.
Buy the Brane X if the ranking matters more than the price. Buy the Marshall Stockwell 2 if the price matters more than the ranking.

The Two Speakers In Full
Brane X: $500 Amazon
Pros: Very deep bass, the absolute deepest from this category. Medium bass boost is the most balanced.
Cons: Boosted upper bass ~120hz, rolled off treble, so it’s missing detail up top. Battery life isn’t great in real world use. High priced. Annoying robot voice announcements. A lot of aux input latency.
