Features Ultra Small Size And Light Weight Co-Axial Point Source Stunning Output-To-Size Ratio 1500 Watt Class D Powersoft Amplifier Bi-Amped Self-Powered, Built-In DSP Description Product Description The DJ112 is extremely small relative to its output. Because the tweeter exits through the middle of the woofer, the extra area that the tweeter would ordinarily take up on the front of the loudspeaker is eliminated. It's barely bigger than a 12 inch woofer but also incorporates a 1.4 inch exit compression driver with a 3 inch voice coil. Featuring a 1500-watt class D Powersoft amplifier with built-in digital signal processing, the DJ112 is bi-amped and has a full complement of protections, limiters and equalizers that ensure consistent, accurate and reliable operation. Amplification and processing is included, so it is fully self-contained and needs only power and signal to be ready to go. Unique angle-cut corner design has a securely attaching threaded pole-mounting system.
