[QUOTE="Charlie Hughes, post: 34916, member: 474"] Re: Why Do TEF Systems read 3-5 dB high ? Many times the rated impedance of a driver is modified by changing both the wire size (resistivity) and the number of windings (total length) for the voice coil. The total resistance is the resistivity, measured in ohms/meter, multiplied by the total length. An 8 ohm driver can be changed into a 16 ohm driver by using smaller wire and more windings. Both of these changes increase DCR. The small wire size has less mass per meter so that the longer total length for the 16 ohm VC can often come close to the same mass as the 8 ohm VC. [/QUOTE]
