DALI Sub C-8 D Active Subwoofer

DALI Sub C-8 D Active Subwoofer

A basic overview of the C-8D:

This high-yield amplifier will have the stamina to give you that outstanding performance and the leeway to pump out that extra power when needed. This amplifier is very flexible with its connectivity, with the choices of an LFE or LINE inputs. The design of the C-8D is 'Simple yet Elegant' the cabinet is designed to fit perfectly to the size of the woofer, with this outstanding design, you will have the capability to produce a 'Powerful Bass Performance'. The rigid cone structure based on aluminium or cone fibre will eliminate the need for a dust cap.

A detailed review of the C-8D:

Amplifier

The integrated 170 Watt RMS Class D amplifier is a highly linear construction. This amp is designed not for only continuous power, but to also hit that peak performance for the customer, the C-8D is able to deliver a substantial 220 Watt peak power (this is very vital when it comes to both music and movie signals). To improve the sound reproduction and to secure that performance under difficult circumstances, a limiter has been incorporated in the amplifier section. The integrated amplifier works in two areas: It compares the input signal amplitude to the potential output signal level, and it compares the available supply voltage from the power supply to the expected output signal. If any of these comparisons show the potential problem, the limiter will cut the signal in a soft manner and without affecting peak power. The C-8D is fitted with controls for gain, cut-off frequency and phase, the amp is able to adapt to any front speaker and room acoustics with the choice of LFE and LINE inputs, making it accessible to almost any amplifier, receiver or processor. The C-8D has a very low power consumption thanks to the 'Switch Mode Power Supply' - giving off only 0.4 Watts in standby mode. The amplifier displays a superb efficiency of 70%, resulting in an absolute minimum of heat loss.

Woofer

The C-8D is equipped with an 8" down-firing woofer. The cone is constructed from high-quality paper pulp, resulting in a rigid cone with excellent breakup characteristics whilst being lightweight and agile at the same time. The engine of the woofer is built around an 'over-sized' ferrite magnet and optimised for maximum flux within the voice of the coil gap. The voice coil is 26.5 mm long and built for long excursions. It is 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 the free movement of the cone without any over/under pressure affecting the performance. Adhering to the low-loss sound design, the surround of the woofer is built to allow long and linear excursion.

Cabinet

The cabinet is made out of a solid MDF; it is designed and manufactured to meet all the required specifications. The cabinet comes in a choice of Black ASH or White Finish, usually, these two types of colours will blend in perfectly in your rooms. 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.

Who is DALI?

DALI is an acronym of 'Danish Audiophile Loudspeaker Industries. As the name suggests, DALI is a Danish company that specialises in designing, engineering and manufacturing high-end and intermediate-level audiophile speaker units. The company was founded in 1983 by a man named Peter Lyngdorf and has since expanded from the confines of Denmark, and can now be found sold all over the world as a well sought-after brand of speakers.
