B&C DE780TN 1.4-Inch Compression Driver - 110W RMS, 16 Ohm

The B&C DE780TN with shrink-ray technology may not have escaped the 1990s, B&C have succeeded in creating two more highly compact drivers, not only permitting close spacing but also reducing weight and cost at the same time. In a larger, 3-inch coil B&C now offer the DE780: Designed with a sonic character like B&C's famous DE900TN, but in a 112mm diameter package weighing only 3.5 lb (1.6kg). Continuous power handling of 220W combined with 108dB sensitivity primes this driver for consideration in a new generation of lighter, more compact line array loudspeakers.
