Beyma 15P80FE/N - Subwoofer 15" 8ohm 101dB 800W Ferrite

Low and mid-range focussed, the Beyma 15MC700Nd bass speaker has an AES power rating of 800 Watts at 8 Ohms and effortlessly spans the 30 to 4,000Hz frequency range. Reinforced by an FEA optimised magnet construction and a 4 inch P80 Series copper voice coil, the sensitivity is taken up to 101 decibels to guarantee high-performance and forceful and effective excursion linearity. To protect it against the elements, the cone has been finished with a special coating.
