Paper Cone Mid/Bass
The 18w 8542-01 is a 6" mid/bass utilising a light paper cone, which is coated on the back face to produce a smooth natural bass.
The patented SD-1 magnet system is designed to almost eliminate modulation and dynamic distortion, whilst the low loss linear suspension and foam surround combines dynamic linearity and low colouration.
