Medium Size Portable Bluetooth Speakers
Ranked #102 of 142 in Medium Size Portable Bluetooth Speakers - Marshall Emberton III: $159.99 Amazon eBay
Pros: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic.
Cons: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud. Not really any different from the Emberton II except having the treble turned down a little bit.

Large Size Portable Bluetooth Speakers
Ranked #28 of 77 in Large Size Portable Bluetooth Speakers - Marshall Middleton II: $330 Amazon eBay
Pros: Very deep bass for the size/weight.
Cons: Bass boosted which drowns out the midrange. Dip around 200hz, peak at 1khz, dipped at 1.6khz. Strange frequency response through the mids.

Ranked #31 of 77 in Large Size Portable Bluetooth Speakers - Marshall Middleton: $224.90 Amazon eBay
Pros: Very deep bass for the size/weight.
Cons: 5db dip at 1.7khz and 6.3khz. 9khz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.
