Power Core One Limited

High efficiency digital subwoofer amplifier

The Power Core One Limited is a digital subwoofer amplifier that fulfils the highest performance requirements. The Power Core One Limited delivers a maximum output of 2500 watts at 1 ohm. Even when operated at a demanding 4 ohms it still manages to produce a whopping 1200 watts of power. To ensure good heat dissipation, which is essential in such a high performance device, the One Limited has been equipped with an active fan in addition to a double-sided copper-coated PCB. The phase can be continuously adjusted between 0 and 180 degrees, while a remote control is supplied for controlling the volume. The 41 mm slimline aluminium heat sink is very narrow and an illuminated Magnat logo is accommodated on the elegant hairline surface. The model name is engraved on the device.
