Overview

PRV Audio 18SW2400 18" Subwoofer 8 Ohm

Incorporating a sturdy cast aluminum frame, meticulously designed with slim spokes to curtail reflections directed back at the cone, the structure also integrates strategic force cooling system openings to facilitate optimal airflow for cooling the voice coil.

Driving the voice coil is a substantial ferrite magnet featuring precisely machined top and bottom plates. Further enhancing performance, the coil benefits from an additional dual forced vent within the back plate, contributing to its capability to handle up to 2400 watts RMS seamlessly.

The driver showcases a distinctive paper cone composition, boasting remarkable high-strength pulp, meticulously engineered to ensure optimal linearity across the mid-frequency range. This is complemented by a specialized cone treatment that enhances the dampening properties of the moving assembly, thereby significantly refining the overall smoothness of its frequency response.

The voice coil, meticulously wound around a 4" glass fiber utilizing copper wire, maintains minimal weight for exceptionally rapid transient response. Engineered with a generous 31 mm winding depth, this inside/outside voice coil configuration guarantees robust thermal resilience and mechanical durability.
