Which is the loudest Bluetooth speaker?

The best Bluetooth speaker for high volumes 

Everybody knows that when you throw a party, you must have several speakers to keep the beat going. While there are different kinds of wired speakers, the best for mobility are ones that use Bluetooth technology.

This makes it easy to move around to ensure the entire area can hear things clearly. However, not just any Bluetooth speaker will do. It needs to be powerful enough compared to the size of the room or outdoor space. If you’re planning the ultimate party, get one of the loudest Bluetooth speaker options on the market.

It’s all in the decibels

Decibels are the universal measurement of how loud something is. While the measurement is objective (depending on how close you are to it), the levels can be explained through everyday things.

For example, a normal conversation is around 60 decibels, and a ringing phone is about 80 decibels. But as the volume increases, so too do the decibels, and when it reaches a certain level, it’s dangerous to your hearing.

Being exposed to sounds of 100 decibels (about the loudness of a bulldozer) for just 15 minutes a day can lead to permanent hearing loss. In under two minutes a day, exposing yourself to sounds over 110 decibels can damage your hearing permanently. This includes a hammer drill, jet engine or a 12-gauge shotgun.

With that in mind, one of the loudest Bluetooth speakers can crank up all the way to 126 decibels. That is equivalent to an ambulance siren or standing directly in front of the speakers at a rock concert.

That’s mighty loud, but these speakers have some additional technology to ensure sound quality. Any speaker can go as loud as the sound system allows, but many will blow out or distort even before reaching the maximum.

However, speakers designed to go as loud as possible use complex diaphragms. For example, in addition to the subwoofers, you’ll often find a compression driver tweeter for the midrange and high notes. This small diaphragm speaker generates the sound in a horn loudspeaker, blasting the audio over a large area.

It’s also common for these speakers to have a built-in amplifier, as it’s challenging for smaller devices to reach the same loudness with only their internal components. Then lastly, the speakers have a frequency range from 40 hertz to 20 kilohertz, which is well within the range of human hearing.

Combined with flexible diaphragms and purpose-built software, all those factors let the speakers play audio at ear-screeching levels without distortion.

Battery power is crucial

Most Bluetooth speakers are powered by a rechargeable battery that easily connects to a USB cable. That might be good enough for a small speaker when listening to music with friends or watching movies, but it certainly won’t do for audio behemoths.

The bigger the speaker gets, the more power it needs to operate. Some of the loudest Bluetooth speakers don’t even have batteries, as their power requirements are so high that they need to run off the mains. It is only through the constant supply that additional features, such as the Bluetooth connectivity, LED lights and wireless chargers, can work.

However, that isn’t always the case with loud wireless speakers. Several manufacturers, such as Ultimate Ears and JBL, have figured out how to cram a high-capacity battery into their portable speakers. Of course, you’ll need to charge it more regularly than a small gadget, but even then, it can last for six or seven hours.
