Like any engineering venture, the choice of material for a loudspeaker diaphragm, also referred to as a cone due to its typical contour, comes with a set of trade-offs that will impact performance. Often, the benefit of a given material for one performance goal poses a setback for another purpose – or purposes. Even for … Continue reading “From the Loudspeaker Diaphragm”

When designing a loudspeaker, several parameters must be considered, not the least of which is the magnet. Different materials provide unique characteristics that vary to meet different application needs. Some common needs are summarized in the chart below. Anyone pulling apart their stereo speakers in the 70s or 80s is likely familiar with the traditional … Continue reading “Loudspeakers: A Look at Magnets”

Likely the widest array of building materials in loudspeakers arises in the choice for the diaphragm (cone), surround, and gasket. These choices yield subtle but profound differences in acoustic performance. They can affect key design outcomes like Thiele-Small parameters and high frequency rolloff, or address performance concerns in different environments. So, let’s look at the … Continue reading “Loudspeakers: A Look at Mylar and Santoprene”
