Doomsday 18 by Avatar
The Doomsday 18 Subwoofer from Avatar is an 18-inch subwoofer that impresses with its powerful bass. With a continuous power handling of 3,500 Watts RMS and a maximum peak power of 7,000 Watts, it is ideal for deep bass applications. The massive 4-inch aluminum voice coil ensures maximum thermal handling, while the extremely low resonance frequency of 29.00 Hz allows for deep, palpable bass. A stable aluminum die-cast basket contributes to the construction designed for torsional rigidity, keeping the entire system secure and free from resonance. The various dual-ohm versions (D1 and D2) also provide flexibility for amplifier connections.
