Product Research
Features
TMD® Surround: The TMD® (Tuned Mass Damper) surround has a unique profile, designed to better control the effects of resonance and reduce the distortion associated with deformations of the cone.
Progressive Spider: The spider is designed to reproduce bass impact while optimizing linearity, precision, and dynamics.
Dual 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω load.
Sealed Box: Focal recommends a sealed enclosure volume of 1.0 ft³, resulting in a -3 db point of 39 Hz. They also list the minimum volume as 0.35 ft³. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable for all types of music.
Ported Box: The recommended ported enclosure volume is 1.5 ft³ with a 4" diameter x 21" long port, which generates a -3 db point of 30 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.

Absolutely beautiful subwoofer! This has full size output with an almost 4" mounting depth You certainly pay a premium for the Utopia line but they are worth every penny. These subs can dig low and have very low distortion. Wonderful for a sound quality setup!
