Loudness / maximum volume

For its compact size, the Charge 6 can play impressively loud, maintaining a big, substantial presentation at higher volumes that suits energetic listening and outdoor gatherings, and a stereo pair can comfortably cover an average basement or backyard party.

Reviewers find the SoundLink Max surprisingly loud for its compact size, easily filling typical rooms and outdoor spaces, and note that while it can push to very high volumes, bass-heavy tracks sound cleaner and more balanced if you avoid maximum volume and run it closer to three-quarters output.

Listeners report that the LS50 Wireless II can play surprisingly loud for compact stand-mount speakers, easily filling small to medium rooms and even larger spaces when not pushed to extremes. They tend to maintain composure and clarity close to their practical limits, delivering powerful, room-filling sound before much larger systems are needed for significantly more slam.

With roughly 580W of power the bar gets loud enough for medium to large rooms, delivering cinematic dynamics and impact, and reviewers note that the main bar itself stays very loud and composed even when pushed, even if ultimate slam still trails the very best flagship separates.

Tests consistently show that the xBoom Bounce can play very loud for its compact size, easily filling small rooms or outdoor gatherings, though pushing into the top volume range also exposes some harshness and compression that make a mid to high volume sweet spot sound best.

Most reviews agree the Move 2 gets loud enough to fill small and medium rooms or patios and even stand up to outdoor breeze and ambient noise, approaching the output of larger boombox-style Bluetooth speakers while retaining useful headroom; it still sounds best kept a notch below maximum rather than as a full-on party rig.

Despite its palm sized footprint the Wonderboom 4 reaches impressive volume levels and can comfortably fill small to medium rooms or outdoor hangouts, but reviewers note that it is not the biggest sounding speaker for its size and that pushing it toward maximum can make the cabinet vibrate and the sound lose composure.

Reviewers agree the Flex 2 gets impressively loud for its small footprint and can fill typical rooms or small outdoor spaces, but note that bigger rivals like JBL and UE still play a bit louder and that running near maximum volume both compresses the sound somewhat and drains the battery in just a few hours.

Most reviewers agree that the StormBox Mini+ can get reasonably loud for its size and fill a small room or casual outdoor gathering, with this review finding it can reach neighbor-annoying decibel levels, though its limited bass and small drivers mean that some listeners find its loudness more reminiscent of an overdriven phone speaker than a truly enjoyable party sound.

The LS50 Meta can play surprisingly loud for a compact stand mount and stays composed at higher levels in small to medium rooms, but it cannot match the effortless volume and scale of larger speakers.

Offers enough volume for bedrooms and small living rooms, but lacks the headroom to convincingly fill larger spaces.
