Hifonics Zeus ZSPL12D2 | 30 cm Subwoofer

HiFonics ZSPL12D2 – SPL Subwoofer from the Zeus Series

For those seeking a powerful SPL subwoofer without breaking the bank, the HiFonics ZSPL12D2 is the perfect choice. With a power handling of up to 1,200 watts in music operation and a short-term peak of 1,800 watts, this 12-inch beast sets new standards in its class. Visually and technically, the ZSPL12D2 shows clear parallels to the Zeus ZXT Extreme series. The special RSA surround (Reinforced Structure Array) is designed for extreme excursions and ensures precise cone movement while preventing unwanted oscillation. The particularly robust carbon-composite dust cap further stabilizes the cone – a crucial feature at high SPL levels.

The enormous power is provided by a 120-ounce dual magnet drive combined with a large 64 mm dual voice coil (2 + 2 Ω) and a winding length of 38 mm. The result is a ±26 mm Xmax excursion, generating massive air movement and creating extreme pressure in the vehicle. Thanks to an efficient cooling system, the voice coil remains thermally stable even under high continuous loads. The ZSPL12D2 performs best in bass reflex enclosures starting from 45 liters in volume – ideally 55–60 liters, where it fully unleashes its deep bass potential.
