Premium speakers
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.
