Speaker SEAS LOTUS MIDRANGE L0021-04S ( RM120 )

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.
Gold plated terminals mounted on a glass fi bre reinforced plate reduce contact resistance
and improve reliability.
