Features
The Monitor Audio Silver Series subwoofer delivers seismic bass right down to 22 Hz using a powerful, long throw 12-inch driver. The Silver W-12’s over-specified driver assembly employs a hugely powerful magnet system and massive voice coil to deliver immense power from the compact sealed cabinet. A heavy-duty diecast basket not only holds the massive system rigidly together, but also assists thermal sinking to keep the driver cool.
For the Silver W-12 subwoofer Monitor Audio specified a 500-watt Class-D amplifier and power-supply module from highly-regarded amplifier specialist Hypex; this provides incredible headroom and utilises advanced switch-mode power conversion techniques. A powerful DSP has been employed to deliver the best performance and filter characteristics, while running the unique APC (Automatic Position Correction) system. The APC is a completely in-house development, designed to automatically correct for room modes. It uses a microphone and test tones to calculate detrimental room modes and correct frequency response, optimising it for the room and position. This is a simple and quick automated process that is a complete revelation to the installer and ensures the user can enjoy the subwoofer quality without positioning restrictions. 
At the heart of the Silver W-12 lies a sophisticated 32-bit micro-controller, monitoring performance thousands of times per second, ensuring the system can deliver the best possible bass. It will never become over-driven or distorted, even at maximum power.
