Web28 jan. 2013 · Thiele/Small parameters were created from the hard work of (wait for it!) A.N. Thiele and Richard Small, who, through experimentation, came up with a method of measuring certain features (parameters) of a driver and how they mathematically influence the design in which the driver is to be used. morpeth wharfhttp://www.diyaudioprojects.com/Technical/Thiele-Small-Parameters/ morpeth windowsWeb27 okt. 2009 · Measured in tesla-metres (T·m). Technically this is B×l or B×l sin (θ) (a vector cross product), but the standard geometry of a circular coil in an annular voice coil gap gives sin (θ)=1. B×l is also known as the 'force factor' because the force on the coil imposed by the magnet is B×l multiplied by the current through the coil. mor peynirhttp://www.claudionegro.com/ morpeth woodfire pizza menuWebSpeaker Workshop: y ou will find useful information on how to project an acoustic speaker using a freeware program.
