TM1A Midrange Tweeter

 

The TM1-A founds the microminiature knockdown High-midrange.
TM1-A-It is Top-class microminiature book-shelf 3-way of ideal choice
Easy to mount compact size common face plate; Extremely close location of drivers resulting in "point source " radiation; 50mm treated fabric dome midrange; 28mm treated fabric dome tweeter with ferrofluid cooled voice coil; Shielded Neodymium magnet systems; Drivers with vented central pole pieces and large non-resonant acoustic chambers; Detachable back caps for critical "flat" applications.
The TM1-A assembly is the long awaited combination of drivers which will eliminate many limitations in contemporary loudspeaker design. The midrange unit is the DMN model with 50 mm aluminum voice coil and hand-treated fabric dome. The DMN has a uniform acoustic power dispersion in the most critical frequency band. This driver allows an acoustically smooth and natural transition to the tweeter, creating a very open, clean and lifelike sound.
The tweeter is the TN28 model with band treated fabric dome and 28 mm ferrofluid cooled voice coil. Both drivers have vented magnet systems and streamlined rear acoustic chambers, which provide better sound quality by suppressing internal reflections. The drivers have symmetrical "sandwich" type Neodymium magnet systems. Two Neodymium magnets from both sides of the top plate create a "sandwich " type system, which provides symmetric electromagnetic properties In the motor structure , reducing distortion. As a result of their close proximity, the drivers create a sound field similar to that of a "point source" radiator. This results in a wide and open soundstage and balanced and accurate reproduction.
The TM1-A assembly is a very versatile product that will provide design flexibility and benefits in home theater, compact high performance stereo, and in-wall system designs. The frequency response and specifications are given for the combination with the recommended crossover frequency and order.
