Sub Bass
Celestion CF1840H 18" Sub Bass (CF1840H)
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 CF1840H 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 4" high temperature voice coil with glass fibre former provides huge power handling and efficient cooling.
The 4 Ohm impedance and low qts is ideally suited to compact single 18 sub bass speakers.
