CONSTRUCTION OF C.D SPEAKER DOUBLE MAGNET OF SIX AND HALF INCHES DIAMETER 150 WATTS 18 IMPEDANCE

ABSTRACT  The project work on construction of loud speaker involves some critical research and study concerned electromagnetic induction effect in transducers like loud speaker and its associated parameter required to chose a very good one this parameters are the power rating of loud speaker and the coil. The sizes were also put into consideration. During the packaging of the loud speaker box a signal conditioning R.C network was build and coupled into the system which take care of the treble and bass boss for the entire speaker signal output   TABLE OF CONTENTS  Certificate  Title page Approval page Dedication  Acknowledgement Abstract  Table of contents
