JBL Boombox - 3 Speakers

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

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.

The sound on this speaker is big and detailed for the most part. That part is pretty awesome. However, when sitting in the sun, the metal handle absorbs A LOT of heat. Because of this, the speaker gets really hot in the sun. And it doesn’t have to be that hot, it has happened to me in mid 70s weather. When it gets too hot, the passive radiators on the side expand like a balloon. It affects the sound quality and the bass pretty dramatically. Because of this, you’re better off using the speaker in the shade or cooler areas. Which is interesting because of all the advertising of it sitting in the sun, hmmm… Also, I’m no engineer, but I feel like the racetrack subwoofer on the front should maybe be on the back of the speaker or something, so that the vibrations can resonate off the walls when placed in front of one? And then the tweeters probably shouldn’t be stacked directly on top of the mid speakers? Idk, just a suggestion I guess. Don’t get me wrong, I enjoy the sound and looks of this speaker in general. I just feel that when it comes to tech specs this speaker could be a little better with its size and space available on it. And not to mention the price…

Great portable speaker, good for everything. I love it

Speaker is one of the best purchases I’ve made. Sounds awesome and even better when plugged in to outlet for more power. Not to heavy but beefy and rugged. It definitely stands out

I got the boombox 3 for Father's day and love the full range sound it has at lower volumes. Perfect for small yards with close neibors you don't want to bother. It will play loud and rock too.

love the boombox 3,its loud with deep bass. only one problem, its not 24 hour playtime! more like 6 or 7 hours

I bought the Boombox 3 several months ago and I absolutely LOVE IT. The sound quality paired with the massive bass on this thing is a beast! I highly recommend buying one for yourself if you haven’t already!

Not 24hr charge. I recently purchased one for my husbands birthday. We have used it twice and out of those times it only plays 2hrs and then dies, completely. Sounds is amazing, great design/build. However, I am highly disappointed in how mine is not lasting on a full charge.

I’ve been wanting to own one but cannot decide what brand or model I like. Finally bought this and was so excited. I used it immediately upon arrival (which was earlier than the initial date). But less than an hour it stopped. It hanged, and the buttons remained on and won’t bulge no matter what I do. Gave it several hours and see what will happen, but sad to say, nothing. I can’t use it. Returned it the same day. The only consolation is, with Target, it’s easy to return and no hassle.

I bought one Boombox 3 & found out that I loved it so much that I bought a second Boombox 3. I tell my friends that there a bit like potato chips and you can’t just have one. Best speakers ever!🤩🤩🤩

I bought it a week ago and I love everything about it. From the sound quality to the looks of it, everything is perfect.

I’ve had this speaker going on 2 years maybe it’s always the show stopper the bass is massive and the clarity and has nice volume don’t hesitate on buying you won’t be disappointed

I bought this speaker about a month ago It was lasting about 16 hours at 80% volume until last weekend When I was lucky to get 5 hours out of it at the same volume It has great sound but the battery life is horrible

Very good Full On Sound from The BoomBox3 Having recently purchased both the Charge5 & Xtreme3 in the last month or so and being so impressed with the build quality, sound & the user friendly JBL ap - I decided to also purchase this Boombox3 - and must say am also most pleased with it - The sound while not hugely louder than the Xtreme and Charge5 - the Sound is very rich & full on and well worth the purchase.

Purchased this around a month ago and l am loving it it’s a great design very well built great sound from the subwoofer midrange and tweeters with a very impressive 80W output

I received this as a gift but think it is a amazing speaker great sound and equalizer adjustments. i use it in my work shop love listening to music while i create.

The boombox was a prize I won at a company party. I was surprised at how heavy the unit is, but the sound is amazing.

I was blown away by this speaker!! The sound and bass are unbelievable!!

The JBL Boombox3 is amazing. The sound is truly amazing.
