ERSE’s IQ laminated steel core coils offer a very low DCR, while maintaining high saturation levels and low distortion ratings. The IQ line of coils is especially designed for frequencies below 8,000 Hz and is ideal when used in a woofer circuits. The specially molded bobbin can handle high temperatures and is easy to mount with screws or rivets.
