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.
