Celestion's CF series is their latest, most technologically advanced range of high performance loudspeakers and is to be found in many top speaker brand high end designs.

The CF1840JD is typical of the series and offers the following features
A lightweight, robust cast chassis designed to minimise reflection back to the cone to reduce acoustic distortion
Balanced airflow venting to maximise voice coil cooling to control thermal compression and increase power handling
FEA optimised magnet topology ensures even distribution of magnet flux in the air gap.
Double suspension systems with "flexiroll" surrounds ensure maximum control of the cone over large excursions.
A dual layer, inside/outside voice coil with glass fibre former provides massive power handling and efficient cooling.
