Beyma 15WRS400 - Woofer 15" 8ohm 98.5dB 400W Ferrite

The Beyma 15WRS400 wide range low-mid bass speaker pushes a 400 Watt AES power output at 8 Ohms, has a 40Hz to 4000Hz frequency range and a 98.5 decibel sensitivity level so it can be installed to support an array of systems. To ensure consistent, high-end performance backed up by low harmonic distortion, this speaker also features a 3 inch copper voice coil and a magnetic circuit that fully complies with FEA norms; a 30mm peak-to-peak maximum excursion; and a weather-proofed cone.
