One of the biggest additions to theXv5lineup is also the smallest.
The Xv5-8 is the first 8" subwoofer FI Car Audio has ever offered, bringing something completely new to the FI lineup while remaining unmistakably FI. Built from the ground up as a true 8" platform, theXv5-8 utilizes a dual-stacked ferrite motor, 2" 4-layer D1/D2 voice coil, dual 6.3" progressive spiders with a spacer, and a high-roll surround, with power handling rated at 500 watts RMS.
It's a completely new size and platform for FI, built for applications where space and cone area are limited but customers still want the construction, appearance, and performance philosophy of an FI subwoofer.
For the larger models, theXv5-10,Xv5-12,Xv5-15, andXv5-18 utilize a 3" 4-layer D1/D2 voice coil and are rated at 1500 watts RMS. The 15" and 18" models receive an additional 12mm—or approximately 1/2"—of voice coil winding to accommodate their larger suspension systems and the additional movement available from those platforms. Combined with their dual-stacked ferrite motor structures, eachXv5is built around the requirements of its specific cone and suspension size rather than simply using the exact same moving assembly across the lineup.
Suspension throughout theXv5lineup is built around dual progressive spiders with an integrated spider spacer, with each suspension sized specifically for the application. TheXv5-8 utilizes dual 6.3" progressive spiders, the 10" and 12" use dual 7.5" progressive spiders, and the 15" and 18" step up to larger dual 8.25" progressive spiders. To complement that larger suspension and its available movement, the 15" and 18" also utilize the additional 12mm of voice coil winding, allowing the coil and suspension to work together as a complete system.
TheXv5-8 also features a high-roll surround, providing the clearance needed for the smaller-diameter platform to achieve its intended excursion. Across the entireXv5lineup, the surround is reinforced at the cone with a stitched surround-to-cone joint, adding mechanical strength to one of the most highly stressed areas of the moving assembly.
EveryXv5is finished with a standard carbon fiber dust cap, maintaining the clean, recognizable FI appearance across the entire series.
From the all-new 8"—a size never before offered by FI—to the massive 18", theXv5lineup is the most complete X Series yet. Each size is purpose-built around its specific platform, giving customers the ability to choose the space, cone area, and output their system demands while maintaining the same core X Series philosophy.
The goal with V5 is simple: continue refining one of FI's most versatile subwoofer platforms while expanding what the X Series can be—without losing the performance, durability, value, and unmistakable FI DNA that have always defined it.
