Overview of our technologies

Quality you can trust: The Ultima 20 are among the best bookshelf speakers in their price class. Our developers in Berlin made sure this stereo pair has the best-possible sound thanks to the following:
- Large 25 mm tweeters for a silky, soft treble
- Large 165 mm midrange drivers with phase plug produce balanced, evenly dispersed sound
- Trumpet bass reflex vents eliminate wind noise and chuffing for deep, clean bass
- Klippel-optimized drivers ensure an incredibly balanced frequency response
Each driver has been optimized by first-class Klippel technology – a first for speakers in this price class. This precision calibration technology allows the Ultima 20 to produce linear and balanced playback. Bass reflex ports with trumpet vents enhance the bass without wind noise. Well-braced wooden enclosures minimize vibrations resulting in a very clean sound.
The Ultima 20 Mk2 scores points on style with harmoniously rounded edges, compact dimensions, and cleverly accented drivers – a self-confident look sure to enhance any interior. The speakers can be seamlessly integrated into any home, fitting easily on either a shelf, wall, or floor stand.



For simple music enjoyment or blasting a party playlist: The cd receiver combines power and sophistication. Enjoy hi-fi sound at any volume level thanks to the following:
- Low noise Class AB amplifier with 2 x 40 watts
- High-end audio components, high-performance power adapter
- Balanced tuning with large power reserves and deep bass
- Full metal enclosure with dial and solid screw terminals / headphone output



CDs, music from USB sticks or the radio: The Kombo 42 plays back everything with panache. Additional inputs make it possible to connect devices like televisions, smartphones and MP3 players.
Thanks to RDS technology, station names are communicated on the display and up to 40 stations can be saved. A handy remote makes it easy to control all system functions. The display shows the titles currently playing.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.
A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
