DALI Sub C-8D Subwoofer
- Winner of Highest "Five Star" Award by What Hi-Fi? Magazine (as part of DALI Spektor 2 5.1)
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 us that a subwoofer can render a performance true to the input signal. Though featuring a 8” down-firing woofer, the SUB C-8 D is everything but a ‘boombox’.
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 performances, the SUB C-8 D is able to deliver 220 Watt Peak Power. This is very relevant when it comes to 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 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 potential problem, the limiter will cut the signal in a soft manner and without affecting peak power.
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 displays an impressive efficiency of 70%. In unison the high-efficiency amplifier section and power supply construction generate an absolute minimum of heat loss. For that reason you will find no external heat sink on the SUB C-8 D.
