Energy efficient TK315A subwoofer from C-Mark

The TK315A is a digital powered three-way full range subwoofer from C-Mark, a product that has been designed to be energy efficient and environmentally friendly due to the inclusion of Class-D power amplifier circuits.

The subwoofer incorporates C-Mark’s one-magnet-three-loop technologies, which combine together to produce a high frequency up to 18kHz and a low frequency down to 40Hz. The TK315A’s three-way coaxial driver utilises this loop technology, meaning that the high, low, and sub frequencies produce sound in the same axis point. This ensures that all frequency sounds are synchronized simultaneously, eliminating any issues of time difference.

Meanwhile, pre-amplifier components utilise three-way crossover circuits, which include independent gain settings for high, medium and low frequencies.

C-Mark highlights the subwoofers ease-of use, and claims non-professional users can operate it easily. It also features an efficient and safe dynamic compression function to control its power output, and incorporates a temperature protection circuit into its design.

Using PFC technology switching power supply components, the TK315A adapts a universal power supply from AC 100V to 240V at 50/60Hz.
