Celestion's PowerPro speakers offer cutting edge design and technology to ensure superb performance and reliability in the most demanding applications.
The PowerProX18 is a brand new design suited to mid size reflex enclosures and offers the following featuresA 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 results in an average 20 degree drop in voice coil temperature.
FEA optimised magnet topology ensures even distribution of magnet flux in the air gap.
A Polysiloxane coated double suspension system with "flexiroll" surround ensures maximum control of the cone over large excursions.
The glass loaded cellulose cone has a weather resistant coating on both the front and rear.
An Aluminium demodulation ring ensures minimum distortion at cone excursion extremes.
A 4 inch high power voice coil with glass fibre former provides massive power handling and efficient cooling.
