Wom300_vDIY is a 12inch woofer, dedicated to passionate and DIY community.
The motor structure is based on 170mm diameter Fe magnet, it uses 2 Aluminum rings and advanced pole pieces geometry to get symmetric and linear force factor and inductance.
Membrane has been engineered with FEA. It is made of pressed paper with handmade in France treatment, and Carbone fiber dust cap.
The typical use case is a 2 ways high-efficiency system using compression driver for upper frequency. We suggest to associate the Wom300_vDIY with the Cmp50_vPA-S (crossover point around 1500Hz) or with Cmp65_vPA (crossover point around 900Hz).
