Compared to our industry standard 18LW2400, the 18LW2420 provides higher maximum SPL, increased program power handling and lower power compression. The 100 mm (4 in) inside-outside copper voice coil based on Interleaved Sandwich Voice coil (ISV) technology provides high levels of thermal stability and durability. || Transducer design features a large displacement suspension system which, in conjunction with a fiberglass reinforced, straight ribbed cone, allows for an ultra-linear piston action and provides full mechanical control across the entire working range. The 100 mm (4 in) inside-outside copper voice coil based on Interleaved Sandwich Voice coil (ISV) technology provides high levels of thermal stability and durability.
