2. JBL PartyBox 300

JBL PartyBox 300

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

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.

Our Score

9.3

out of 10

Verdict
AMAZING
The surest way to piss off your neighbors, the Aiwa Exos 9 delivers a whopping 200 watts of power with massive sound and big bass
