Thiele Small Parameters

The Thiele Small Parameters (often referred to as T/S Parameters) are provided in specification sheets by most manufacturers – but what are they for? If you read through the section on parameters you’ll get a more detailed explanation on the significance of each parameter, but put simply they are a set of parameters which define […]

Driver TS Parameters: Re (DC Resistance) & Le (Voice Coil Inductance)

Re is the DC resistance of the loudspeaker’s voice coil, you should not confuse this with impedance, although related, the two are different. Measuring the resistance of a speaker with a multi-meter, the reading you get across the terminals should be close to the manufacturer’s specified Re, it’s not unusual to get a minor variation […]
