DEEP BASS,
BY DESIGN.

RAD is our Repel-Attract Driver. It uses a custom array of magnets to overcome the air pressure forces that normally keep deep bass out of portable speakers. True subwoofer depth, in a fraction of the size.

  • Outside

    “It makes other portable speakers sound like toys.”

    “The first mobile speaker that allows users to hear everything the artist intended.”

  • Wirecutter

    “When we heard how clearly the Brane X outperformed several leading portable wireless speakers, we couldn't help but get excited.”

  • TechRadar

  • Wired

    “This compact but mighty speaker lets you bring the thrills of a real subwoofer virtually anywhere.”

Sound this deep has never been this small.

FULL-RANGE SOUND

HEAR WHAT YOU’RE MISSING

Most portable speakers can’t reproduce anything below 50 Hz, so up to a quarter of the low end never reaches you.

Brane X plays down to 27.1 Hz, the deep notes other speakers drop. You hear the song the way it was recorded.
