Current Build: Stealth Install, 1989 F-150 Lariat


































































































4th Order Bandpass Build for Colby P. from New Mexico


For this build, we chose 13-ply 3/4" Baltic Birch instead of MDF.  This added significant strength for only a minimal weight penalty.


Here is one method used for accurate cross-cuts.




Building the outside walls of the sealed chamber.


13 plies, count them.


Laying out the baffle position.


Test fitting the baffles.


Recessed subwoofer mounting holes.  This allows approximately 1-1/8" of baffle, or about 15 plies.


This partition was installed to fine-tune the volume of the vented chamber.


Installing the port sides.



First top-plate installed, with access panel hole.  Note the roundover on the vent to help create a flared opening.




Close-up of seams, and recessed subwoofer holes.



Aluminum tape applied to the second top-plate to help seal the opening.


Closed-cell foam applied as a gasket.


More aluminum tape and CCF on the inner top-plate.


Subwoofer enclosure with removable top in place.


Final delivery: roundover applied to corners, box shipped ready for sanding and paint.
