TM-1201 Mid-Frequency Loudspeaker

The concept behind the TM-1201 mid-frequency loudspeaker is smooth frequency response combined with high efficiency and low distortion at all power levels. It covers a range from 200 to 3,000Hz.
DIAPHRAGM The diaphragm cone of the TM-1201 is made of our exclusive Polymer Graphite (PG*). PG is characterized by low density, high Young's modulus and high internal loss. This means it provides smooth response, high efficiency, low distortion, excellent power linearity, and, most importantly, clean sound reproduction without a hint of unnatural coloration. The surround for the diaphragm is a corrugated cloth coated with a damping material to improve internal loss. It helps achieve ideal linear response and low overall distortion.
VOICE COIL The PG cone is driven by a semi-long travel voice coil 7/16 inches (11mm) wide, edgewise-wound on the bobbin. It assures powerful, low-distortion reproduction at virtually all input levels, and high efficiency.
MAGNETIC CIRCUIT The large-sized ferrite magnet (8 lbs./3.6kg) helps yield a high air gap magnetic flux density of 14,500G. It results in high efficiency with extremely low distortion.
HOUSING A sturdy low-resonance aluminum alloy diecast frame is used in the TM-1201 to support the magnetic structure and moving parts of the loudspeaker
CROSSOVER It is recommended that the TM-1201 be used with an active crossover network (band-pass filter) having crossover frequencies at approximately 200Hz and 3kHz, and cutoff characteristics of 12dB/oct. or 18dB/oct
