Speaker Driver Woofer / Midbass Aluminium 60W 8Ω 89dB 35Hz-8000Hz Ø20.3cm

This Dayton Audio DA215-8 bass / low-midrange driver benefits from a particularly rigid and well-damped Aluminium cone, allowing it to deliver deep, clear bass and low-midrange sound with extremely low distortion. When used with a well thought-out crossover filter, it is possible with this DA215-8 to achieve a linear frequency response, ideal for faithful sound reproduction.
