These are not really the same size class, and that is the honest framing here. The Bose SoundLink Plus ranks #25 of 120 large speakers by sound quality at $179; the JBL Boombox 4 ranks #20 of 113 boombox speakers by sound quality at $549.95.

Different sizes. The SoundLink Plus is a large 3.3 lbs (1.5 kg) stereo speaker. The Boombox 4 is a 13.2 lbs (6 kg) boombox. Each is rated within its own class.
The Boombox 4 measured about 115dB with bass to about 41Hz, is IP68, and claims 28 hours from a removable battery. Use the Oluv EQ linked on its page.
The SoundLink Plus is IP67 with close to 20 hours of battery. Its bass is boosted and thuddy, and it has no EQ.
Buy the Bose SoundLink Plus ($179) for a large speaker; the JBL Boombox 4 ($549.95) suits a boombox speaker instead.
