The Loudest Bluetooth Speakers (2021 Updated)
The loudest and most powerful speaker in 2021…
The SOUNDBOKS 3 is among the loudest and most powerful Bluetooth speaker we have ever tested, and is a significant upgrade from the previous two version of the SOUNDBOKS speaker.
The amount of volume that the SOUNDBOKS 3 can produce is extreme – it delivers up to 126 dB of sound (which is equivalent to the sound level of an airplane engine taking off), and also comes equipped with 40 hours of battery life for portable sound.
Apart from its extreme sound output, the speaker is also ideal for outdoors with its splash proof durable design and is built to last.
The speaker is fully wireless, and connects to smartphone devices via Bluetooth, or aux / XLR inputs if required.
The bottom line is, if you are looking for one of the loudest and best quality Bluetooth speaker, the SOUNDBOKS 3 has tonnes to offer and more. The level of clarity, loudness and battery life that this speaker has is among the very best, if not the best in the market at the time of writing.

The loudest JBL Speaker currently available…
Now if you are looking for a speaker with serious sound output, the JBL PartyBox 300 should definitely be on your list.
This is the loudest JBL speaker on the market at the moment, and it delivers JBL signature sound with plenty of bass and loud volume output. It is essentially a portable PA speaker system with JBL’s full panel lighting design for an exciting visual experience.
The bass on the PartyBox 300 is exceptionally loud – it’s like having almost 10X JBL Boomboxes in one room – it’s that LOUD and powerful.
The only issue with the PartyBox 300 is how big the speaker is. Although it’s still portable, it is at least 4 times heavier than the Boombox. Carrying it around is no joke, so be sure you want to get this speaker of this massive size before you buy.
In terms of loudness, the speaker goes way louder than what normal human ears can tolerate. At low volume it feels like having a JBL Boombox at mid-high volume levels (in comparison). The volume and bass is clean and deep, and sounds well-defined without any noticeable distortion.
Overall the PartyBox 300 is definitely a massive beast with incredibly loud sound output, and a few notches louder than the JBL Boombox 2.

3. Aiwa Exos 9
Probably the reason why your neighbors hate you…
The Aiwa Exos 9 has a reputation for its unbearably loud volume and tremendous bass performance.
If you are looking for a speaker that WILL piss off your neighbours, this is probably it.
The Exos 9 has up to 200 watts of power with 5 speaker drivers, including a 6.5” subwoofer for deeper bass and crisp highs. The speaker has great bass that can be “felt” and heard even in outdoor open spaces.
The volume that this speaker produces is MASSIVE. The volume gets so loud that you can hear it across a wide open field clearly – it’s the type of speaker that you’d bring to a large outdoor party and blast music all day.
One thing that stands out with this speaker is its on-board 5 band graphic equalizer which allows you to set the bass, mids or highs. The customizable EQ is pretty awesome, especially if you want to change your music genre to something like EDM or rock or hip-hop.
The battery itself lasts of 8-9 hours which isn’t bad but slightly below what the competition has to offer. Our only quibble with the Exos 9 speaker is its lack of waterproofing – but the amount of volume and sound that you get out from this thing more than makes up for its shortfalls.

The JBL Boombox 2 represents a significant upgrade from JBL’s original Boombox, with more powerful sound, deeper bass and longer battery life.
This is JBL’s loudest Boombox on the market and it pumps out deep and powerful bass with two bass subwoofers at the sides of the speaker.
When you push the bass to maximum on this speaker, you can literally see the bass subwoofers at both sides wobbling and the bass depth that this speaker has is quite incredible. EDM songs and pop soundtracks sound exhilarating to listen to – it brings new life to your music with clear and loud sound.
Apart from the fact that the JBL Boombox 2 is built like a tank, it features 24 hours of playtime and doubles as a power bank to charge your smartphone devices. It’s also FULLY waterproof (IPX7 rated), which means you can actually submerge the speaker underwater without any issues.
Compared to the original Boombox, the Boombox 2 is around 20% louder and has more bass, but retains all of the functionality that you’d find in the Boombox 1.

9. JBL Xtreme 3
A more portable option for outdoor music…
Now if you are looking for a loud Bluetooth speaker that isn’t as huge as the JBL Boombox, go for the JBL Xtreme 3.
The Xtreme 3 is much louder and more powerful than all the other portable speakers in the JBL line of speakers, and delivers really loud JBL sound quality. It features four drivers and two JBL bass radiators at the sides with plenty of bass detail.
One thing that I really like about the Xtreme 3 is the level of bass that you get – it feels deep and solid, and every drum beat can be heard through the speaker with crystal clarity. It certainly does feel like a portable subwoofer sometimes.
Another awesome feature that the Xtreme 3 has is the partyboost functionality which allows you to pair multiple Xtreme 3 speakers for a much louder sound experience – all from a single Bluetooth source.
To top it off, the Xtreme 3 is IP67 waterproof rated and is fully waterproof and dustproof. It’s a speaker that excels as an outdoor portable speaker and doesn’t disappoint.

The speaker can deliver incredibly loud volume on par with the JBL Boombox 2, and is the largest and most powerful speaker in the VGX family line of speakers.
The speaker itself is very sturdy and is equipped with a built-in battery that delivers 10 hours of playtime (or 3.5 hours at maximum volume output level). It’s also water-resistant for the outdoors and comes with a built-in handle for portability. The moment you put your hands on this speaker, you can tell that it’s a solidly built speaker unit.
The audio reproduction on this speaker is massive and gets very LOUD. That said, you can hear the details in the music at every layer – the highs are crisp, the mids are strong and the bass is deep and has plenty of depth. The volume feels massive but doesn’t distort – it’s the perfect party speaker to blast music outdoors and you can hear your music clearly.
The bass on the VG7 speaker gets pretty deep too – EDM and rock music genres sound punchy and very enjoyable. The beats are deep and have plenty of depth; it does feel like a subwoofer a certain levels.
