The diaphragm is frequently made from thin aluminum sheet. although paper or polyester film may also be used. The impedance of the ceramic microphone is capacitative, on the order of 500-1 000 pF.

How a Speaker Works – What I’ve Learned So Far Francis Deck Introduction I’m a bassist. I’m also interested in electronics, physics, and building my own gear. When I was still in high school, back in 1981, I was intrigued by the idea of building a speaker, and discovered a book about speaker design in the library. watts of clean, reliable audio for public address applications.They are ruggedly designed to give years of reliable service. They are equipped with toroidal power transformers, extensive heat-sinking, and fan cooling and protective circuits. 100V, 70V and 4-16 Ohms transformer isolated speaker outputs

However, some speakers require an amplifier with a low damping factor to reproduce rich, full-bodied sound. The E-202 has a Speaker Damping Control which permits choice of three damping factors and induces maximum potential performance from any speaker. Damping factor with an 8 ohm load becomes more than 50 when this control is set to NORMAL.
Guitar. On guitar, damping (also referred to as choking) is a technique where, shortly after playing the strings, the sound is reduced by pressing the right hand palm against the strings, right hand damping (including palm muting), or relaxing the left hand fingers' pressure on the strings, left hand damping (or left-hand muting).
