The aim of the Classic Series is to maintain Supravox’s philosophy of developing high performance broadband speakers. We are working to further extend the useful bandwidth for the highest possible efficiency, while continuously improving the definition, quality and linearity of response. From 135 to 380 mm diameter, the audiophile can satisfy his passion.

Supravox, starting from a blank page but based on its long experience, redefines what a large-diameter high-fidelity woofer is: neutral and dynamic. 18 months of research and development is revealed in the new Supravox 380 series.

The 380 GMF high-efficiency woofer (97.8 dB) is the twin of the 380 GMF PRO: this version is dedicated to high-fidelity/monitoring use.

It covers the 40-500Hz bandwidth in 165L tuned at 35Hz (recommended vents: 2* PVC 160mm by 30cm).

Its new motor uses a 76mm flat copper wire coil wound on a 20mm field, combined with a profiled core, this assembly offers a symmetrical travel over +/- 7mm.

Two aluminium demodulation rings stabilize the motor field, but also reduce, linearize and symmetrize the Le(x).

The moving parts take advantage of our new exponential cone, This one by the formulation of its paper offers a better damping for clarity and definition, while ensuring by its profile a greater rigidity offering a reduced distortion in the low register.

This all-new driver outperforms our previous 400 FMGs in every respect: linearity of response, clarity of sound, dynamic range, thermal and mechanical handling, and significantly reduced distortion.
