HELIX S 4X – 4″ 2-Way Coaxial Car Speakers | 120W Peak Power
The HELIX S 4X is a premium 4-inch (100 mm) 2-way coaxial car speaker system from the new HELIX S Series, designed to deliver exceptional sound quality, elegant design, and a highly detailed listening experience. Developed by Audiotec Fischer, the S 4X combines advanced materials, precise engineering, and refined acoustics to transform every drive into a premium audio experience.
Featuring a 19 mm coated silk dome tweeter positioned in the center of the mid-woofer, the S 4X creates a true point-source effect, resulting in a more natural and homogeneous sound image. The combination of smooth high frequencies and a lightweight basalt-fiber-paper compound cone ensures excellent clarity, accurate vocals, and controlled midrange reproduction.
With 120 W maximum power handling, 60 W RMS, and a dedicated external crossover, the HELIX S 4X is an ideal upgrade for factory audio systems and performs exceptionally well when combined with an external amplifier.

Advanced Materials for Natural Sound
The HELIX S 4X uses an innovative basalt-fiber-paper compound cone, combining low weight, high stiffness, and excellent internal damping. This construction allows the speaker to reproduce music with outstanding accuracy while maintaining clean and distortion-free performance even at higher volume levels.
The specially designed rubber surround increases the effective cone area and improves excursion capability, resulting in stronger and more controlled midrange performance.
Smooth High Frequencies and Perfect Balance
The centrally mounted 19 mm silk dome tweeter creates a balanced point-source sound image, improving stereo imaging and tonal consistency. The coated silk dome provides smooth, detailed treble reproduction with minimal compression effects, delivering natural vocals and precise instrument detail.
The result is a wide, realistic, and enjoyable listening experience.
Designed for Amplified Systems
While the HELIX S 4X works efficiently with factory head units, it reaches its full potential when paired with an Audiotec Fischer amplifier or DSP amplifier. Additional power allows the speaker to deliver greater dynamics, improved control, and higher volume levels with excellent clarity.
