Short answer: the Aiwa Exos-10, if you are buying new. The Aiwa Exos-9 ranks higher than the Yeahbox Sonic Boom Max 3 (#9 vs #59 of 113 boombox speakers) but is discontinued; its replacement, the Aiwa Exos-10, is rated 3.5/5 at $399.99 and is still sold new.
The case for the Aiwa Exos-9: Still a great sounding speaker even against today’s models. The tradeoff: Features are lacking, generally not recommended anymore, not sold new anymore.
What the Yeahbox Sonic Boom Max 3 gets right: 200W RMS (300W peak) true 3-way, 5-driver array. Set against that: A budget import brand with limited independent testing - specs are manufacturer-claimed.
Buy the Aiwa Exos-10, the replacement for the discontinued Aiwa Exos-9; it is rated higher for sound quality than the Yeahbox Sonic Boom Max 3.
Water resistance is not close: the Yeahbox Sonic Boom Max 3 is rated at IPX6 (powerful water jets), well ahead of the Aiwa Exos-9 at no water resistance.
