I have the Classic Audio Loudspeakers T1.5 Field Coils 16 Ohms and the T3.4 Field Coils also at 16ohms.
All the Drivers use TAD, John Wolff modifies the TAD Drivers and converts them to Field Coils this takes allot of work and money to do. However they are absolutely musical.

TAD drivers even with out the Field coil conversions perform at very high levels are are known to be one of the best drivers arround.
