Beyma 6MI100 - Midwoofer 6" 8ohm 94dB 250W Ferrite

This mid-low frequency sound transducer focuses on three important factors: high power handling (97 dB), controlled sound development up to approx. 3 kHz and a low distortion factor. These features favor the use of the sound transducer in high-quality sound systems, especially for live use. The chassis is equipped with a die-cast aluminum basket that reduces mechanical vibrations and optimizes heat dissipation. These features as well as the use of a high-quality 2" voice coil increase the load capacity of the chassis up to approx. 250 WAES.
