When hi-fi nerds set out to build a boombox

The BOOMSTER XL is the result: A powerful, portable all-in-one speaker with the best sound in its price class. And no wonder. The same acoustic engineers who developed Teufel's award-winning high-end stereo speaker, the Definion 5, are also responsible for the BOOMSTER XL.

Technical highlights at a glance:
  • 3-way stereo system for balanced, true-to-source sound
  • Two tweeters capture the finest details in all genres of music
  • Two midrange drivers ensure that vocals are played back with naturalness and warmth
  • Giant downfire subwoofer produces powerful, dry and very deep bass
  • An extremely low-noise class D amplifier with an 80 watt maximum power capacity generates high, distortion-free levels in even large rooms
  • 2 band equalizer makes it easy to adjust sound levels

Handy feature: Subwoofer levels can be adjusted from that of a subtle sonic foundation to room-shaking bass attack - and everything in between. The choice is yours.

Wireless is more: Bluetooth 4.0 with aptX

Bluetooth 4.0 with the aptX compression algorithm guarantees stable wireless audio transmission in CD quality along with minimal power usage. Even movie soundtracks are played back in perfect sync and a range of 10 meters allows the user to control the system from anywhere in the room.

NFC technology makes it possible for smartphones to pair with the BOOMSTER XL by simply bringing the two devices into close proximity. The system can memorize the profile of up to 6 different devices such as smartphones and tablets for instant connectivity.

For longer excursions

The BOOMSTER XL has a high-capacity lithium ion battery with a long runtime for musical adventures far from power outlets.

A handy USB charging socket even lets you charge your smartphone with an up to 2 amp charging current.

The BOOMSTER XL is made from highly robust yet attractive anodized aluminium and is even splash proof – nice to know when out and about in the great outdoors. Practical rubberized handles and a rubber slip-proof bottom add to the system’s portability and placement options. A handy carry strap attaches magnetically to a clever bayonet mount and can be easily removed.

Flexible playback options

A 3.5 mm jack socket supports devices with mini stereo jacks. This allows for a range of source options in addition to Bluetooth.

The integrated FM radio uses an external antenna for maximum reception and features a seek function to help you find the perfect radio station no matter where you are. Three preset buttons can be programmed with your favourite stations for even faster access to your music.

Look ma, no hands!

The BOOMSTER XL uses an integrated microphone for hands-free telephony. Move through the kitchen preparing dinner while chatting with friends – your smartphone doesn’t need to be glued to your ear. When a call is received, music playback automatically stops so your mother won’t get an earful of BOOMSTER bass. Once the call is complete, your music can continue where it left off.


But how does the BOOMSTER XL compare to that other great next-generation boombox from Teufel, the BOOMSTER? While both systems are capable of impressive sound pressure levels, the BOOMSTER XL has no problem filling even very large spaces of 30 square meters with sound or serving as the sole sound system for outdoor parties. It’s up to you to decide just how much boom you require. Both systems produce hi-fi playback with truly impressive bass.

Test the BOOMSTER XL for up to 8 weeks.
