If you want your audio to fill a large, crowded room at a party or you listen to music outdoors, you'll want a speaker that can get pretty loud, with little compression present at maximum volume. High compression levels at max volume degrade audio quality and affect how clean and clear audio reproduces as you bump up the speaker's volume. Most speakers that can get quite loud tend to be larger and bulkier and aren't very portable. However, the best large Bluetooth speakers' sizes also help them produce more extended low bass than their smaller counterparts.
We've tested over 180 speakers, and below, you'll find our recommendations for the best loud Bluetooth speakers. See our recommendations for the best speakers for parties, the best Bluetooth speakers, and the best Bluetooth speakers for bass.

Loudest Bluetooth Speaker
SPL @ Max Volume109.4 dB SPLBuild Quality6.4Music7.3Outdoors5.3Controls7.0Frequency Response Accuracy8.3StereoNo (mono)See all our test resultsBluetooth8.3The JBL PartyBox 1000 is the loudest Bluetooth speaker we've tested. With a measured max volume just shy of 110 decibels, this powerful party speaker easily fills large spaces with music. Its balanced sound means vocals and instruments are reproduced with clarity and detail, while the added punch and boom in the bass region bring genres like EDM and hip-hop to life. Unfortunately, it downmixes your audio to mono, so you'll need to get another unit for stereo playback. However, two of these will really get the party started.
This speaker comes with party-centric additions like mic and guitar inputs for when you simply have to rock out alongside your favorite tunes or indulge in a little karaoke with friends. There's no companion app, but there are plenty of physical controls on the unit to customize your experience. While there's no true EQ, the BassBoost button lets you access two extra levels of bass, perfect for the techno nerds among us. Remember that this hefty speaker doesn't have a battery, so you'll need to plug it in. Still, if you only plan on having one speaker instead of making a pair, the Sony ULT TOWER 9AC might be worth a look, given that it's a stereo speaker. However, its controls aren't as intuitive, and it has a bassier voicing.

Loudest Upper Mid-Range Bluetooth Speaker
SPL @ Max Volume106.6 dB SPLBuild Quality6.4Music6.4Outdoors6.6Controls4.9Frequency Response Accuracy6.5StereoNo (mono)Bluetooth8.2See all our test resultsBattery7.8For something a little less pricey than our top pick, check out the SOUNDBOKS Go. It's another booming party speaker that's much smaller and lighter than the JBL PartyBox 1000. We measured this speaker's max volume at just shy of 107 dB/SPL, which is more than enough to fill larger spaces with the sound of your favorite tunes. This speaker also gives you access to the SOUNDBOKS app, where you can find a graphic EQ to customize its sound and connectivity features to pair multiple SOUNDBOKS devices together so you can amplify sound across a larger space.
Unlike the flatter sound of the JBL, this speaker offers a V-shaped sound profile out of the box. While this means voices and lead instruments can sound a little hollow, they're still clear and present. Hi-hats and cymbals also sound bright and exciting. This speaker is smaller than our top pick, so, unsurprisingly, it doesn't put out as much low bass, but there's plenty of extra mid and high bass, which adds punch to kick drums and warmth to basslines. This speaker also lasts 35 hours off a single charge, which is great for all-night parties, too.

Loudest Mid-Range Bluetooth Speaker
SPL @ Max Volume105.2 dB SPLBuild Quality7.0Music7.9Outdoors7.9Controls8.0Frequency Response Accuracy8.1StereoYesBluetooth8.2See all our test resultsBattery9.1If you're shopping for a mid-range speaker with impressive volume on tap, the JBL PartyBox Stage 320 is worth a look. It's one of the loudest Bluetooth speakers we've tested and is available at a more budget-friendly price than our top picks. Its measured max volume of just over 105 dB/SPL falls a little short of the SOUNDBOKS Go, which is a little more overbuilt in design too, but the JBL still delivers more than enough volume to fill your backyard with sound. This speaker is designed for parties, and its customizable RGB lights can help set the mood for your next big event, but it can be overkill if you don't have the space.
This device ranks among the best large Bluetooth speakers we've tested. It has a balanced sound that ensures voices and lead instruments remain clear while the bass is present and punchy without overwhelming the mix. If you prefer a different sound, you're in luck. The PartyBox app features a five-band graphic EQ to adjust the speaker's tone to your taste. With its added microphone and guitar inputs, you might find it's the perfect accompaniment to your next karaoke BBQ sing-off. Worth acknowledging is that the JBL PartyBox 520 gets louder at max volume (109 dB/SPL), but its battery life is roughly half, it weighs an extra 20 or so pounds, and it usually costs more, which lands it in the realm of diminishing returns for most people.

Loudest Lower Mid-Range Bluetooth Speaker
SPL @ Max Volume98.8 dB SPLBuild Quality7.0Music7.7Outdoors7.7Controls7.0Frequency Response Accuracy7.8StereoYesBluetooth8.0See all our test resultsBattery8.4The JBL Partybox Club 120 is a smaller and more affordable cousin to the JBL PartyBox Stage 320 and comes without wheels, which makes it a little less convenient in some ways. At nearly 99 decibels, it doesn't get quite as loud as the more premium picks on this list, but it still has enough volume for a crowded party or outdoor gathering with not too much compression. Plus, you get access to many of the same party features, including guitar and microphone inputs, which are handy if you want to host a round of karaoke at your next event. Its RGB lights are a cool touch, and you can also customize them to fit the ambiance of your party.
As its name implies, this speaker is a great choice for bass-heavy music genres like house, EDM, and hip-hop. Out of the box, it has a touch of bass emphasis with balanced mid and treble ranges that ensure vocals and lead instruments still come through clearly. You can set its Bass Boost feature to 'Deep' or 'Punchy' to add even more oomph to your music or adjust the sound with the graphic EQ and presets in the JBL PartyBox app. It doesn't offer as long a battery life as its higher-end cousin, but it's a solid pick, especially if you're shopping with a budget in mind.

Loudest Budget Bluetooth Speaker
SPL @ Max Volume93.1 dB SPLBuild Quality7.0Music6.5Outdoors7.0Controls7.9Frequency Response Accuracy6.4StereoYesBluetooth6.7See all our test resultsBattery8.5Looking for a budget-friendly Bluetooth speaker? Check out the Anker Soundcore Motion Boom. With a max output of 93 dB/SPL, it's not the loudest speaker on the list, but it's also the least expensive. Plus, you could buy a second identical speaker to increase the overall headroom at a relatively low cost and make a stereo pair. Weighing a very slight 1.5 kg (3.4 lbs), it's also the smallest speaker on the list. Its controls are clear and easy to use. Still, its tuning isn't nearly as balanced as the JBL PartyBox Club 120, nor does it have any physical inputs, so it's strictly Bluetooth-only.
That said, you can access a graphic EQ and presets in its companion app to change its somewhat mid-range boosted sound. The 22-hour battery life is rather impressive for its size, but it takes six hours to fully recharge. While it has an IPX7 rating against water exposure, the overall build is a bit plasticky and not necessarily going to hold up if it takes several tumbles. Even so, the speaker represents an affordable option for getting a loud speaker for not much cash.

Best Portable Loud Bluetooth Speaker
SPL @ Max Volume101.8 dB SPLBuild Quality8.6Music7.2Outdoors8.1Controls6.9Frequency Response Accuracy7.2StereoYesBluetooth7.6See all our test resultsBattery9.2If you want to take your party with you, the JBL Boombox 4 is the best loud and portable Bluetooth speaker. Its chunky handle makes it easy to carry single-handedly, while its 101 dB/SPL max output can hold down the party on its own. Plus, unlike larger party speakers, such as the JBL PartyBox Stage 320, it doesn't need to be wheeled to the location, and it boasts an IP68 rating, indicating it's protected from dust and water exposure. Equipped with a remarkable 40-hour battery life that can be swapped for another removable battery means that with this speaker, the party ends when you want it to, not when the battery drains.
This speaker has a very neutral tuning that reproduces a variety of music genres evenly, with extra bass boost features available. You can also use the companion app's EQ to add more bass, boost the mids, or roll off the treble, and so on, to suit your tastes. Unlike its larger counterparts, like the JBL PartyBox Club 120, you don't get the flexibility of mic or instrument inputs, making it a strictly music playback speaker. However, if you're content with only 10 hours of battery life, the Sony ULT FIELD 7 is another portable and loud Bluetooth speaker that comes with a combo mic or instrument input, as well as more comprehensive hands-on physical controls. But it doesn't get quite as loud as the JBL.

ION Pathfinder 320:
The ION Pathfinder 320 is a great alternative to the Anker Soundcore Motion Boom if you want an incredibly long battery life and a bit more volume, but it's a bit more costly than the Anker with a less even frequency response.
See our review -
Brane X:
The Brane X is a portable smart speaker that packs a big bass punch in a small frame. It's not quite as loud as the JBL Boombox 4, but there's considerably more compression at max volume. It's also quite a bit more expensive. That said, the Brane has some premium features, like Wi-Fi and Alexa compatibility, that help it stand out from the crowd.

All Reviews
Our recommendations above are what we think are currently the best loud wireless Bluetooth speakers for most people, according to their needs. We factor in the price (cheaper speakers win over pricier ones if the difference isn't worth it), feedback from our visitors, and availability (no speakers that are difficult to find or almost out of stock everywhere).
If you would like to see more products, here's the list of all our speaker reviews sorted by their max volume levels. Be careful not to get caught up in the details. There are no perfect speakers. Personal taste, preference, and listening habits will matter more in your selection.
