The auna Dr. Red Boom is a portable Bluetooth speaker that brings background music to a wide variety of outdoor activities. 

For professional sound reinforcement are two 7.6cm (3 ") treble / midrange and a 13cm (5.25") woofer in a bass reflex cabinet in a tubular form.

The equipment includes an built-in Bluetooth interface for wireless transmission of music from your smartphone, tablet or laptop, as well as an MP3-compatible USB port and SD memory card slot for direct music playback from USB flash drives, MP3 players and memory cards. The auna Dr. Black Boom also features an FM radio tuner with automatic station search and over 30 memory locations. Wired devices such as mobile phones, CD or MP3 players, and other external audio sources may be connected via the AUX input.

The built-in battery stands out with its long operating time and frees the auna Dr. Red Boom speaker of any need for a permanent power supply. The battery charging is done easily via USB cable connected to your computer. 

Thanks to its clever ergonomics, the housing offers options for horizontal and vertical installation. Vertically positioned, the Dr. Red Boom speaker creates a dynamic sound with a strong bass and an impressive low range. Horizontally, the sound unfolds widely. The folding carrying handle and a carrying strap with snap hook facilitate easy transport.
