Sub 12" Kx-series
The E 30 KX is a 12" (30cm) subwoofer with very high power handling. It has an impressive SPL of 86.5dB (2.83 V/1 m) and a sealed box or bass-reflex type enclosure of 28 to 35L !
The E 30 KX subwoofer takes full advantage of the acoustic qualities of Kevlar® cones. Light, rigid and with excellent damping, they provide extremely dynamic bass. Their yellow colour is legendary of the K2 Power line’s identity.
All the components used for this subwoofer have been optimised to improve performance. The cone is fixed to the frame using a new robust and very reliable rubber suspension, whose exclusive shape has been optimised to provide very high excursion. The aluminium frame has also been redesigned to improve voice coil excursion. All moving parts benefit from this excellent excursion, giving the subwoofer tight, punchy and dynamic bass.
The oversized “Dual Magnet” has been given a new voice coil cooling system to improve cooling and also to improve the subwoofer’s performance and power handling. The progressive spider profile is designed to provide a full-bodied bass to increase linearity, precision and dynamic range.
