JBL Boombox 3 Portable Bluetooth PA Speaker Stereo

Fantastic, but something's not right.

I got this speaker for Christmas last year (2023) and this thing has been AMAZING. - Great build quality - SUPERB sound - Great battery life (as long as you're responsible with EQs and volume) But there are a few gripes I have with this speaker. And this is not just with the bb3. I've seen this happen on my XTREME 2 I used to have, the boombox 2, and some other speakers that have the same driver setup (driver(s) out the front, dual radiators on the side). ### My Main Issue ### The radiators flex aggressively when playing at high volumes and in warmer temperatures. It's probably hard to solve this without creating a hole inside for air pressure which not only makes it non IP67 water/dust resistant, but also would make frequency response poorer with the radiators. But the air inside of the speaker is trapped due to the sealed design, and when the drivers and battery are hard at work, it heats up, i.e. expands. This pushes the radiators out, as if they're about to explode. Then following the slow expansion of air inside, the radiators shake violently, distorting bass and rocking the speaker back and forth. I'd imagine it's not good for the rubber holding everything together and the subwoofer in the center being gyrated in and out at velocities that it's not in control of. Right now the thing is sitting on my bedroom floor. After playing music with lots of bass (smooth sine waves, constantly, 45-55-65 hz), they look inset now! And when lightly pushing on them they barely move. So these radiators are being forcibly held and pushed out, and in. I really hope the engineers saw this and knew that it would be like this. If anyone working for JBL sees this, I don't need a replacement, but I'd like the peace of mind that this is somewhat normal. This guy on reddit seems to be experiencing the same issue: https://www.reddit.com/r/JBL/comments/yrdls0/boombox_3_trapping_air_passive_radiators_getting/ (For people reading the reddit post, don't listen to the comments. No there's no air escape hole but you get the point). I've also included a picture of my inset radiators, just look at those and tell me they don't look stuck in.

Great Speaker - Incredible Sound and Battery Life!

Great speaker with incredible sound quality, convenient portability, and a long lasting battery life! The sound quality is great, even when you turn the volume up to the top. This speaker can get very loud especially for a speaker of this size. This speaker is perfect for any situation. Great for parties, whether that party is a casual barbecue or a bumping pool party. The fact it is waterproof allows you to relax when around water. This speaker is portable so it is very convenient to bring anywhere without having to be plugged in. The battery life lasts a long time as well which means you can use it all day long. It is perfect for playing loud music during workouts as well. This speaker is my new favorite speaker.

Great features and Good Quality Sounds

So far the output is real and distinct. The noise reduction is great and distortion level is spectacular It delivers the music exactly as produced but with amplification and all the clear components
