Unlike some subwoofers, the DALI SUB C-8 D has been engineered to perform equally well on both music and movies. Though featuring a 8” down-firing woofer, the SUB C-8 D can render a true-to-life signal thanks to DALI's persistent engineering work and is everything but a ‘boombox’.

  • 8" down-firing subwoofer and bass port makes for kid- and pet-friendly use
  • High-yield 170W Class D amplifier with 220W peak output
  • Elegant, sleek exterior design
  • LFE and mono / stereo RCA inputs with crossover and phase adjustments for easy integration into any system

Placing a subwoofer is a very large part of creating the perfect audio reproduction. It is recommended to place a subwoofer like the C-8 D ideally in a corner, or alongside a wall as a second choice. 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 with many larger subwoofers.

Over the years DALI engineers have developed a set of sound design principles. Today these are applied in the creation of any DALI speaker. Naturally, subwoofers must be able to enter into any setup without sacrificing the purpose of providing wide dispersion, time coherence and low-loss performance. The DALI SUB C-8 D will feel equally at home in a movie focused surround setup and in a compact stereo setup meant for mainly musical enjoyment.

The integrated 170 Watt RMS Class D amplifier is highly linear. 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 performances, the SUB C-8 D is able to deliver 220 Watts of peak power. This is very important for both movie and music signals.

To improve sound reproduction and to ensure performance under difficult circumstances, a limiter has been incorporated in the amplifier section. The integrated limiter works in two ways: It compares the input signal amplitude to the potential output signal level, and compares the available supply voltage from the power supply to the expected output signal. If any of these comparisons show potential problem, the limiter will reduce the signal discreetly and without affecting peak power.

Fitted with controls for gain, cut-off frequency, and phase, the DALI SUB C-8 D will adapt to any front speakers and room acoustics. And with a choice of LFE and LINE inputs it can be connected to almost any amplifier, receiver or processor.

The switch-mode power supply is part of the reason for very low power consumption - only 0.4 Watt in standby mode. And the amplifier yields an impressive efficiency of 70%. The high-efficiency amplifier section and power supply together generate an absolute minimum of heat loss. For that reason you will find no external heat sink on the SUB C-8 D.

DALI SUB C-8 D is equipped with an 8” down-firing woofer. The cone is constructed from high-quality paper pulp, produce a rigid cone with excellent breakup characteristics while at the same time being very lightweight and agile.

The woofer engine is built around an oversized ferrite magnet and optimised for maximum flux within the voice coil gap. It was crucial for DALI's project team to enable the SUB C-8 D to render the finer low frequency details in music - and also put out high sound pressure levels on request. The measured values indicate that we reached a level of control and precision rarely found in this category at all. And the numerous listening sessions have truly convinced us that this was the right way to go.

The voice coil is 26.5 mm long and built for long excursions, vented to ensure air-cooling to the system, and the benefit is a stable impedance response. The pole piece is likewise vented for maximum cooling, and here the venting also reduces internal compression in the motor system. This ensures free movement of the cone without any over/under pressure affecting performance.

Adhering to the low-loss sound design principle, the surround of the woofer is built to allow long and linear excursion. The over-sized suspension is designed to allow transients small and large to all turn into undistorted acoustic signals.

The solid MDF cabinet is designed and manufactured to meet the tough DALI specifications. Coming in a choice of Black Ash or White finish, it can blend in perfectly with most speaker designs and room decors.

The entire cabinet is effectively decoupled from the floor by means of four polymer based oversized spikes. 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. Still, the proximity to the floor ensures that the benefit of having a down-firing subwoofer is maintained; a higher efficiency and more freedom in positioning.
