Wolfram Audio introduces the Au-15: our unrivaled 15" SPL woofer when it comes to power, performance, and reliability. The Au series features a massive 300oz magnet coupled with a heavily vented magnetic gap for extreme cooling. The Au-15 utilizes a 3" 4-layer high temperature voice coil for an intense amount of power handling.

Au is the chemical symbol for Gold - one of the most rare and valuable metals of the face of the earth. That is exactly why the Au series from Wolfram Audio is the top choice for SPL woofers in it's class.
