Product details
Ported shallow face-down design
FDSSP is zBox’s single-sub shallow box that fires face down and includes one port. The official product page titles it “Single Sub Shallow Box (Face Down) with Single Port,” and product photos show the port opening on the cabinet. This listing is the ported design.
Who it fits
Shallow-mount single subs in trucks, SUVs, and other installs where height is limited. The face-down layout and side legs keep the cone clear of the floor while the port helps move air for a fuller low end than a comparable shallow box without a port.
What’s included
Empty carpeted MDF enclosure with a recessed terminal cup. Pick 8, 10 or 12 inch at checkout. Subwoofer, amp, and install hardware are separate.
