The HOQS C3D Trap Top is a Paraflex-style mid/top speaker cabinet design developed by the High Order Quarterwave Society (HOQS) DIY audio community. This enclosure is widely used as a kick top cabinet in high-output sound systems, delivering strong mid-bass impact, high sensitivity, and excellent projection.
SubCurrent Sound’s CNC-cut flat pack version provides perfectly machined panels for fast, accurate assembly. All joints are precision cut to ensure correct internal geometry, air-tight construction, and consistent performance from build to build.
The C3D Trap Top is commonly configured with 12-inch professional drivers and paired with subwoofers and high-frequency horns to form a complete sound system.
This cabinet is ideal for DIY speaker builders, sound system crews, and custom PA projects looking for a proven Paraflex design with serious output and compact form factor.
