There’s always been a bit of a black art to loudspeaker design. The battle between form and function rages in this field. Several animated discussions have been had over the years concerning what some view as an acoustic delight and what significant others view as a garish monolith. And that’s not even getting to what … Continue reading “Thiele-Small Parameters: The Big Picture”

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”

Any loudspeaker driver is essentially an electric motor. It takes an electrical signal as input, generating motion (and sound) output. Unlike a battery’s steady input causing a wheel to continually spin, we vary the input with a signal generated from an original sound source. The motion starts with the interaction between a current-carrying conductor, the … Continue reading “A Loudspeaker Driver Breakdown”

Likely the widest array of building materials in loudspeakers arises in the choice for the diaphragm (cone), surround, and gasket.
