        Product details

        SEAS Lotus Reference RM120 - L0021-04S Midrange woofer
        The manually coated paper cone and the mechanically matching natural rubber surround
        result in an unusually smooth midrange response.
        Heavy copper rings mounted above and below the T-shaped pole piece reduce non linear
        and modulation distortion and increase overload margin.
         
        The large magnet system provides good sensitivity and transient response.
        The chrome plated brass phase plug reduces compression due to temperature variations
        in the voice coil, increases long term power handling capacity and eliminates resonances
        in the cavity inside the voice coil former.
         
        The extremely stiff and stable injection moulded zinc basket keeps the critical
        components in perfect alignment. Large windows in the basket both above and below the
        spider reduce sound refl exion, air fl ow noise and cavity resonance to a minimum.
        Goldplated terminals mounted on a glass fibre reinforced plate reduce contact resistance
        and improve reliability.
