These are not really the same size class, and that is the honest framing here. The Milwaukee M18 Jobsite Speaker 2891-20 ranks #105 of 114 large speakers by sound quality at $166.41; the Turtlebox Gen 3 ranks #103 of 111 boombox speakers by sound quality at $430. Both are rated below 3.0/5 for their class (114 large speakers and 111 boombox speakers), so if sound quality matters, look higher up the rankings.
The Milwaukee M18 Jobsite Speaker 2891-20 is the lighter option. One of the louder jobsite speakers in reviews, with stereo sound from two woofers, two tweeters and two passive radiators on a rated 40W, and clear vocals. At 5.3 lbs (2.4 kg) it weighs much less than the Turtlebox Gen 3 at 10 lbs (4.54 kg). The catch: Its bass is nowhere near as deep as top ranked large speakers like the JBL Xtreme 5 and Tribit Stormbox Lava, which reach down to about 43 Hz and 44 Hz.
The Turtlebox Gen 3 is the longer-running, tougher choice. Waterproof (IP67, and it floats) and crushproof, with stainless steel hardware and quality amplifier parts inside. It is rated for 25 hours of battery against 10 for the Milwaukee M18 Jobsite Speaker 2891-20. It is rated IP67 against IP54 for the Milwaukee M18 Jobsite Speaker 2891-20. It has a microphone input for karaoke or announcements, which the Milwaukee M18 Jobsite Speaker 2891-20 lacks. Watch for: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
Buy the Milwaukee M18 Jobsite Speaker 2891-20 ($166.41) for a large speaker; the Turtlebox Gen 3 ($430) suits a boombox speaker instead.
