THUNDER 1845

The Ahuja THUNDER 1845 is a super-power low-frequency driver crafted for demanding sound-reinforcement and subwoofer speaker applications. Built around a robust 18″ diaphragm and an efficient 11.43 cm (4.5″) copper voice coil, it delivers extended low-frequency response with high acoustic pressure and reliable operation under heavy load. The vented aluminium die-cast frame with integrated heat sinks and a heavy-duty ferrite magnet assembly ensures enhanced heat dissipation and durability, making this speaker suitable for professional PA subwoofer enclosures and high-power bass systems.

With a nominal impedance of 8 Ω and sensitivity around 97 dB (1 W/1 m), the THUNDER 1845 efficiently converts amplifier power into impactful bass output that fills large venues and outdoor setups. Its composite-treated cone and heavy-duty terminals provide strength and reliable signal transfer for live performances, large halls, concerts, DJs, and sound-reinforcement rigs that need powerful low-end performance.
