Short answer: the Minirig 4 for modular bass, the Miatone Boompro for a lower price. The Minirig 4 is modular and can easily attach a subwoofer, though it calls itself splash resistant and carries no official water rating. The Boompro lists at $35.99 against $229.95 for the Minirig, but it has slightly less bass extension than higher ranked speakers.
What the Miatone Boompro gets right: Exactly the same as the Wisetiger P3 below. The catch: Slightly less bass extension than higher ranked speakers.
On the Minirig 4 side: Modular, can easily attach a subwoofer. The tradeoff: Calls itself splash resistant and has no official water rating.
Buy the Miatone Boompro if the price is the priority over sound quality, or the Minirig 4 if sound quality is the priority over the price.
There is a real battery-life gap here: the Minirig 4 is rated for 30 hours, the Miatone Boompro only 16 hours.
If water resistance matters to you, the Miatone Boompro at IPX7 (brief submersion) holds up far better than the Minirig 4 at Splash resistant (splashing).
