Exploded drawing


In the first step, the individual panels are cut to size according to the list. Since the material thickness is a standard one and the panels are simply glued together as butt joints, except for the base, it is possible to have all the pieces cut to size in the DIY shop.

To simplify the construction process, it is recommended to start with one side panel and glue to this the rear wall, lid, front panel and channel panel. The slight bevel on the joint between the upper section of the front panel and the channel panel can be cut with a settable jigsaw or circular saw beforehand or angled using a rasp. If you are not using screws or wooden plugs, you can use small nails from which you have cut off the heads, to prevent the panels moving while the glue sets.

After that, place the second side panel in place and fix the cabinet with sash cramps while the glue dries. If you position the cabinet and sash cramps carefully on the workbench, you will still be able to access the hole in the base. Since the base has been designed to be removable and is screwed onto four pieces of beading, the pieces of beading can now be glued in place.

Once the glue has fully dried, the base is fitted in place and drilled through the beading using a fine drill bit. Then, increase the size of the holes in the base ONLY to the actual screw size, and countersink the holes to allow the heads to be fully flush.

If you are intending to veneer the cabinets, now is the time to do it.

In the next step, the speaker openings are shaped using a power router as shown in the drawings (it is recommended to include the surface finish in your calculations so the openings are exactly right) and drill the holes for the speaker fixing points.

Next, wire up the speaker drivers (as shown in the attached wiring diagram), and fit the crossover on the removable base. Finally, distribute the damping material in the cabinet as shown in the drawing and screw the drivers in place.

Inner damping

Insert all three polyester wool mats in the upper third of the cabinet, well compressed but evenly spaced. To do so, it is best to roll up the mats and insert them through the woofer port or the base.
