FOCAL P 20 FSE – 8" Slim Flax Cone Subwoofer (400W)

The FOCAL P 20 FSE is an ultra-compact 8-inch slim subwoofer that delivers impressive 400-watt peak power and natural, distortion-free bass. Designed and made in France by Focal’s expert acoustic engineers, this subwoofer incorporates premium materials and cutting-edge technology to provide a rich, precise low-frequency response—even in tight spaces.

Its unique flax cone, made from a lightweight flax fiber core sandwiched between layers of glass fiber, is the secret to the P 20 FSE’s natural sound quality. This innovative material offers the perfect balance of rigidity and damping, ensuring accurate, punchy bass without unwanted distortion.

The integrated Dual Magnet motor keeps the size compact while delivering powerful output. The robust shaped rubber surround allows for greater excursion, extending the frequency response for deeper bass. Its 38mm voice coil on a glass fiber former ensures better thermal management, reducing the risk of overheating during extended use.

Thanks to its shallow depth and sealed box compatibility (6–9L), the P 20 FSE is a perfect fit for vehicles with limited space, such as behind seats or in side compartments.
