The FlexFit basket and included grille are intended to simplify and finish installations where a compact 12" subwoofer is preferred.
What to know
Match the subwoofer's power and impedance to your amplifier to avoid underpowering or overdriving. VAST technology increases cone area for greater output from the same 12" footprint. The product includes a grille with integral trim ring; confirm enclosure type and size with your installer or reference materials if you…
