FEATURES

• Electroacoustic design optimized for enclosures from 32 liters.
• Flow-dynamic optimization system that drastically reduces acoustic distortions caused by air compression at high excursions.
• Polypropylene cone and dust cap geometry developed through FEM simulations to reduce low-frequency distortion.
• 35 mm 2 Ω voice coil, wound with six layers of pure copper on a fiberglass former with high thermal resistance.
• Magnetic group geometry optimized with proprietary software for high, undistorted sound pressure levels at high excursions.
• Ideal for use in custom boxes that can be shaped around the subwoofer thanks to its compact size and the absence of a decompression hole.
• Terminal block with solid pressure contacts that accept cables up to 8 AWG to ensure low wiring resistance and maximum connection convenience even in multi-subwoofer installations.
• Rubber protection of the magnet assembly and high-strength ABS plastic gasket that allows the attachment of the optional grille for an elegant finish.
