To cut the long story short, the Aiwa Exos 9 is a much more powerful speaker compared to the JBL Boombox and JBL Partybox. The Exos 9 has a power rating of 200 watts compared to the JBL Boombox (40 watts) and JBL Partybox 300 (120 watts). In terms of absolute sound output, the Aiwa Exos 9 is definitely the speaker you should go for.
That being said, the Aiwa Exos 9 is not as portable as the JBL Boombox due to its weight and size. It’s also not IPX7 waterproof rated like the JBL Boombox, which means you cannot use it under wet environments with exposure to water. The JBL Boombox is a really good speaker to have for outdoor and rainy environments.
The JBL Partybox 300, on the other hand, functions more like a portable PA speaker system and comes with party lights for an ambient effect. It’s a really powerful speaker to have with good bass, although it loses out to the Aiwa Exos 9 in terms of absolute volume output.
