T18A / T15A / T12A
Introduction
T18A, T15A and T12A may be easily installed and meet both
the musician's and the sound company's requirements.
They are the ideal choice for those who constantly work both
in large and medium venues, who require a versatile system
and who wish to expand their own PA.
In all three models, two independent MosFet amps for the
high and low frequencies, along with two active processors
and an electronic cross-over, allow to optimize the frequency
response and the sound performance even at low sound levels,
while ensuring clarity and power at higher volumes.
The frequency response of the model T18A extends so
deeply into the lower octaves that the bass quality is full
and engaging without the need for subwoofers.
