Incorporating all the design advantages of the famous
Electro-Voice Radex Caaxial principle, the Electro-Voice Model 12 TRXB
integrated 3-way loudspeaker includes, also, the latest developments in the
reproduction of the highest audible frequencies through the use of an integral
Super Sonax VHF driver.
The 12 TRXB emplous the Model T35B VHF driver
base response is excellent, affording pleasing musical balance without the
masking effects previously experienced from extended high frequency
reproduction.
The 12 TRXB
loudspeaker is designed to meet optimum listening requirements; latest
developments incorporated insure even, smooth coverage of the entire listening
area. The engineered features of the Electro-Voice integrated 3-way speaker
system include true oncentric mounting of all reproducing elements; augmented
balanced bass response in conjunction with smooth, extended high frequency
reproduction, carefully tailored mid-range characteristic to provide realism
and a considerable degree of "presence" at usual sound levels. The 12
TRXB incorporates in the high frequency section the Sonophase throat design.
The
importance of the Sonophase throat design is paramount above 12 kc, where sound
must b taken from the center of the diaphragm and the outer periphery
simultaneously.
At lower
frequencies, where the diaphragm is a piston, and no phase shift is required in
the path configuration, the longer central path length does not appreciably
change the phase due to the longer wave lengths involved. Further benefits are
affored in the high frequency section of the Electro-Voice integrated 3-way
speaker systems by the incorporation of Electro-Voice developed diffraction
horns as the method of achieving the best dispersion. In stereophonic use
especially, a 3 dB concentration of sound in one portionof the subject, with
the resultant distortion of the solid or stereo effect. An adjustable
"brilliance" control is incorporated to allow matching of response to
room acoustic, compensating for high frequency absorptive efects of heavy
drapery and soft frnishhings; crossover network with full 12 dB per octave
slope minimizes distortion; edgewise-wound aluminum voice coil design affords
18% more efficiency and consequent damping of transient distortion.
