About the Interface Delta
The Electro-Voice Interface Delta is a vintage three-way, bass-reflex floorstanding loudspeaker. It uses a 12-inch (305 mm) woofer, a 6.5-inch (165 mm) midrange driver, and an ST350A radial-horn tweeter. Rated at 8 ohms nominal impedance, it has approximately 97 dB sensitivity, a published frequency range of 28 Hz–18 kHz (±2.5 dB), and crossover points at approximately 350 Hz and 3 kHz. Its high sensitivity and substantial power-handling capability make it suitable for high-output applications. It is part of Electro-Voice’s Interface series, but is distinct from the Interface D.
