B&C DE780TN 1.4" 110W Compression Driver 8 Ohm
While 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" coil they now offer the DE780: Designed with a sonic character like the hoghly successful 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.
