To be able to use phase linear filters that does not make the sound “unclean”, advanced loudspeaker drivers with large bandwidth, low distortion and a very regular/continuous frequency, are needed. These loudspeaker drivers are very rare. But our bas/mid register driver is probably one of the best in the world to handle this job. Together the advanced tweeter, the driver and ace-plus® work together in a unique way to create a harmonic unity that reproduces the music exactly the way it was recorded. In a simple and smart manner. Simplicity at its best.

 So, what does ace-plus® actually do for the sound? Ace-plus is incorporated in our hifi system Stereo One. Listeners are amazed over how big such a small system as Stereo One can sound. The sound has an extreme openness, detail richness and fullness. A true to life and mature hifi sound.
