Portable Carbon Fiber Boombox

The Bumpboxx Ultra-CarbonFiber is a 7-pound Bluetooth boombox built for listeners who want high-output sound in a carry-ready package. Its carbon-fiber finish and integrated handle make it suited for outdoor gatherings, travel and mobile use.

From smaller speakers to 140-watt output

Moving up from compact portable speakers, this unit delivers 140 watts max power through two 5.25-inch drivers and two 2-inch tweeters, reaching 110 dB for crowd-scale volume. The jump is worth it when a single box must cover a yard, beach or hall without a PA system.

Build around Bluetooth, TWS and 22-hour battery

Pair a phone or tablet via Bluetooth, link a second Ultra unit with TWS wireless pairing for stereo separation, or plug in through the 3.5 mm line input. The rechargeable lithium battery runs up to 22 hours, freeing the system from mains power for a full day of playback.
