The AP 4 midbass offers very extended frequency response, both in high and low frequencies, combined with high efficiency and features a 25 mm pure copper voice coil to ensure more balance in mid-high frequency ranges.
APX 570 features a concentric coaxial tweeter: with one single point of sound emission it is possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter.
The 5×7″ cones surround features an exclusive shallow “Triple Wave” profile, for maximum excursion linearity.
Sound quality meets elegance – The new S speaker series turns every ride into a special sound experience.
In addition to the novel, timelessly elegant design, the 2-way coaxial system offers an exceptional sound quality. Uniquely sensitive and crystal clear, the silk dome of the tweeter conjures the music into the room. Due to its central position inside the mid-woofer, the music is perceived as a point sound source and thus optimizes the tonal balance. The result: an incredibly homogeneous and natural sound.
The stiff and lightweight diaphragm of the mid-woofer consists of a novel basalt fiber paper compound. A perfect combination to guarantee clear, pure sound even at high volume levels. In conjunction with a power amplifier from Audiotec Fischer, the S coaxial system performs at its best.
Make every ride a special sound experience!
These reference speakers in our C-series raise the bar to a new level of fantastic sound quality. The legendary sisal woofer cones are equipped with an additional structural damping layer made of an elastomer, which again improves the acoustic properties of the driver. The tweeter enclosure also underwent a complete overhaul. Anyone who wants to operate these loudspeakers as fully active speakers (e.g. using our new digital signal processors) can put together the system of their choice by combining the individual components.
The new B-Series loudspeaker (formerly known as “BLUE”) have never been as good as they are today!
With its unique sound characteristics, the new B-Series loudspeakers set a trend for others to follow, and not just by the individual and unique HELIX design. Numerous detail improvements and the use of proven components guarantee maximum power and longevity. The elaborately designed and developed crossovers assure a precise separation of the audio spectrum and a flat frequency response – full, deep bass, gentle middles and detailed heights.
Furthermore, all speakers are designed for easy installation with low effort. Therefore, there is nothing standing in the way of a listening experience with the highest levels.
