    While shrink-ray technology may not have escaped the 1990s, we 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 we now offer the DE780: Designed with a sonic character like our 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.
