DALI SUB C-8 D WHITEPAPER
INTRODUCTION Unlike some subwoofers the DALI SUB C-8 D has been engineered to perform equally well on both music and movies. It is very important to DALI that a subwoofer can render a performance true to the input signal. Therefore a DALI subwoofer is everything but a ‘boombox’. DALI SUB C-8 D DALI A/S www.dali-speakers.

CABINET The solid MDF cabinet is designed and manufactured to meet the tough DALI specifications. The enclosure comes in a choice of Black Ash or White finishes, making it blend perfectly with most speaker designs and room decors. Appearing to hover above the floor the distance of 30 mm eliminates any potential turbulence from the space between the cabinet and the floor itself.
WOOFER DALI SUB C-8 D is equipped with an 8” down-firing woofer. The cone is constructed from a high-quality paper pulp resulting in a rigid cone with excellent breakup characteristics while at the same time being very lightweight and agile. The engine of the woofer is built around an ‘oversized’ ferrite magnet and optimized for maximum flux within the voice coil gap.
AMPLIFIER The integrated 170 Watt RMS Class D amplifier is a highly linear construction. The DALI SUB C-8 D will follow and render the required signal with an absolute minimum of bias. Designed not only for continuous power, but also for peak power, this subwoofer is able to deliver 220 Watt Peak Power. This is very relevant when it comes to both movie and music signals. The switch mode power supply is part of the reason for very low power consumption - only 0.4 Watt in standby mode.
APPLICATION Placing a subwoofer is a very large part of creating the perfect audio reproduction. DALI recommends placing the SUB C-8 D in a corner or if that is not possible alongside a wall. This will maximise the bass output and the distribution around the room. The compact size of the SUB C-8 D makes placing it correctly much easier than many larger subwoofers. Available in Black Ash and White, the SUB C-8 D is the natural companion for many DALI speakers.
