T9 - Loudspeaker Basics and Planar-Magnetics

David Clark, DLC Design - Wixom, MI, USA

The first half of the tutorial covers the transducer, enclosure and listening environment basics:
• Two coupled transducers (motor and radiator)
• Motor types—magnetic, electrostatic, piezoelectric
• Radiator types—cone, membrane, panel, horn
• Simplified physics and energy flow
• Enclosures
• Listening environment

The second half of the tutorial will investigate planar-magnetic transducers in some depth:
• History of planar magnetic speakers
• Ribbon vs. planar-magnetic
• How they work—physical arrangement
• Why they have a fanatic following
• What are the problems in making them work
• Room interface
• Sub-woofers and super-tweeters
