1 2 hours test made with continuous pink noise signal (6 dB crest factor) within the
specified range. Power calculated on rated minimum impedance. Loudspeaker in
free air.
2 Power on Continuous Program is defined as 3 dB greater than the Nominal rating.
3 Applied RMS Voltage is set to 2.83V for 8 ohms Nominal Impedance. Average SPL
from 200 to 1200Hz.
Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-
ditioning test.
15 TBX 40 |Woofer
2000 W power handling, 4" voice coil with very high thermal
capability and a ventilated magnet assembly that allows a low power
compression. A very low distortion figure is obtained using a double
spider design and dual demodulation rings in the magnetic path.
Proprietary water-proof cone treatment for safe use in adverse
climatic conditions. State of the art performance, in the smallest
possible enclosure, set the 15 TBX 40 as a benchmark loudspeaker.
