Which JBL speaker is the loudest?

When shopping for a new speaker, it’s best to look for one with well-balanced audio across the lows, mids and highs, as it makes music sound clearer. Once you’ve checked off all the boxes for a high-quality speaker, high volume output should be your next consideration.

JBL makes high-quality portable speakers. Although Bluetooth speakers typically don’t deliver the same volume as standing speakers, some JBL speakers are impressive for their size and cost. 

In this article: JBL PartyBox 1000, JBL PartyBox 710 and JBL PartyBox 110.

JBL party speakers

Party speakers are bulky and deliver plenty of power output and loud volume. They’re your best bet if you want the loudest speaker possible, but they’re also more expensive than portable Bluetooth speakers. JBL party speakers are also portable, but unlike smaller Bluetooth speakers, you can’t toss one in a bag and travel with it. This makes them more suitable for home or backyard use.

JBL portable Bluetooth speakers

Portable Bluetooth speakers aren’t nearly as loud as party speakers, but they’re good enough for small- to medium-sized gatherings in a home or backyard. Portable Bluetooth speakers are made for traveling. Although some JBL speakers deliver impressive bass and volume for their size, a party speaker is ideal for a gathering of over 30 people.


The more powerful a speaker is, the louder its potential volume output. Generally, a speaker with the capacity to handle more wattage is usually louder than one with a lower capacity.


A speaker with a large physical diameter also has a more significant threshold for the amount of sound the driver and woofer can pump out. Larger speakers aren’t always necessarily louder than smaller speakers, but they can often handle more power.

Sound pressure level

Speakers emit sound pressure waves. The intensity of these waves, when compared to the environment, determines how you perceive volume level. Sound pressure level is measured in decibels. Although it’s uncommon in a party or portable Bluetooth speaker, some specify how many decibels they can crank out. In other words, the higher the decibels, the louder the speaker can get.
