D&B Audiotechnik Z0785.000 KSL-SUB: The Ultimate Cardioid Subwoofer
The KSL-SUB is a cardioid subwoofer that's perfect for enhancing your KSL System. It's a must-have for audiophiles and professionals alike. Here's why:
- • Exceptional bass performance: With a frequency response of 36 Hz to 105 Hz (33 Hz to 75 Hz in INFRA mode), it delivers powerful, accurate low frequencies.
- • Cardioid design: Reduces unwanted energy behind the system, providing a more focused sound and less room reverberation.
- • Versatile setup: Can be flown (KSL-SUB) or ground stacked (KSL-GSUB), and can be used with KSL8 and KSL12 cabinets.
The KSL-SUB cabinet is an actively driven, 2-way bass-reflex design with three long excursion neodymium 15-inch drivers. Two drivers face forward, while one radiates to the rear. The front and rear drivers operate in independent bass reflex chambers and are driven from separate amplifier channels. It also features front and rear rigging strands for easy installation. The cabinets are made of marine plywood and have an impact and weather-protected PCP finish, with rigid metal grills on the front and rear.
