Short answer: the Minirig 4. It ranks #6 of 144 medium speakers by sound quality, rated 4.3/5, at $229.95. The Klipsch Groove/Heritage Groove ranks #95, rated 2.8/5, at $89, $140.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Minirig 4: Modular, can easily attach a subwoofer. The catch: Calls itself splash resistant and has no official water rating.
What the Klipsch Groove/Heritage Groove does well: Pretty balanced sound. The catch: Not stereo.
Buy the Minirig 4. It is rated higher for sound quality, and the $140.95 you would save on the Klipsch Groove/Heritage Groove does not close the gap.
There is a real battery-life gap here: the Minirig 4 is rated for 30 hours, the Klipsch Groove/Heritage Groove only 8 hours.

Klipsch Groove/Heritage Groove: $89.00 Amazon eBay
Pros: Pretty balanced sound. Distinctive mid-century design with real wood veneer and a woven grille, unlike most plastic/rubber portables. ~8 hour battery life.
Cons: Not stereo. Bass doesn’t go as deep as others its size. Gets distorted at higher levels. Wouldn’t generally recommend these old speakers as they can’t compete with modern speakers for bass performance and features.
