Step 1:

Start with one of the side panels, eiher the LEFT (L) or RIGHT (R) panel. In the photos here we used the right panel. The rear edge of this panel is cut at a 12.5° angle, apply a bead of glue to the angled edge.

The handle cut out will be closer to the front (90°) edge, and closer to the BOTTOM of the cabinet.

Step 2:

Ensuring the connector cutout on the back panel is nearest the bottom, with the recessed rebate facing outwards, attach the rear panel to the side panel. Align the edges to be flush as you work your way down from one end to the other.

These panels are the same length, so the ends should also be flush with each other. Where the panels are quite tall, you may find it easier to do this step on the floor, which will also help align the panels lengthways if you have a level flat surface.

Step 3:

Check the top edges of the two panels, they should be flush with no lip. If during assembly one panel is slightly higher than the other, you should sand this to make it flush across the two panels. This will help with ensuring the side and back panels line up correctly with the top panel.

Step 4:

Apply a bead of glue along the top edge of the rear and side panels. From now on you should assume that all joints require a generous bead of glue, and this instruction may be omitted in future steps.

Step 5:

Fetch the TOP panel (1) - note that this is different to the bottom panel as it has an extra rebate that the front panels fits in. The top and bottom panels ARE NOT interchangeable.

Step 6:

Fit the Top Panel to the Rear and Side panels using nails or screws as preferred.

Surplus glue should ooze out from the joint as you screw/nail.

Once you have affixed the top panel securely the speaker is starting to take shape, and is strong enough to be moved around. Its best to do the next step on a table or workbench, so carefully lift the three assembled panels and turn the structure upside down so that the TOP panel is resting on the workbench.

Step 7:

The divider panel (part 3) is next, this needs to be fitted with a distance of 227mm between the divider and the top panel. The easiest way of properly aligning the divider panel is by resting it on pre-cut spacers.

We can supply spacers if required - please ask, these are free of charge.

These spacers are temporary, and are removed before assembly is complete, take care not to glue or pin the spacers as it will make them difficult to remove later

Step 8:

Pin through the side and rear panels into the divider panel. You may find it useful to draw a guideline to indicate the middle of the divider, this should be 250mm from the edge (the 250mm spacer for Step 9 does the job nicely for drawing a guideline)

This is a good time to check everything is lining up correctly, if you offer the front baffle into position, the divider should line up approximately to the edge of the 8" horn cut-out.
.

Step 9:

The next step is to fit the central brace (4). Two spacers 250mm high will position the divider appropriately. Again, we can offer these free of charge if needed, please ask. Remember, the spacers are temporary, so take care not to glue or pin them.

Apply glue to the mating faces of the brace and push firmly into the corner before pinning the panels together from the outside.
 

Step 10:

Leave the partially assembled cabinet to one side whilst you prepare the front baffle. The port needs to be fitted before the baffle is fitted in the cabinet. The port goes on the BOTTOM of the front baffle, below the round cut out for the 15" driver. In the Mk1 kits, the port is made up from pieces 5 and 7, shown in the picture. The updated mk2 kits have combined pieces 5 and 7 into a single part which acts as both port and grille support.

Step 10: (mk1 )

If you have a mk1 kit, glue and pin piece 5 to the front baffle. The port should be cut to the correct size and not overhang the front baffle, if it is slightly oversize, use a belt sander (or similar) to ensure it is flush before proceeding. Piece 7, the front grille support, can be affixed later, with the baffle in situ.

Step 10: (mk2)

The updated mk2 kits have combined pieces 5 and 7 into a single part which acts as both port and grill support. Locate the front baffle in the rebate, and then pin through this panel into the front baffle.

After fitting, check the sides of the port are flush with the front baffle, sanding as required
 

Step 11:

Leaving the spacer supports in place, check the front baffle fits correctly. Do not rush this part as it takes care to get this right. All previous joints have been simpler to assemble as you are generally working with only 2 parts at a time. Here you need to ensure the front baffle fits snugly against the side panel, the brace, the divider and the top panel (currently at the bottom as the cabinet is upside down). There is very little wood around the sides of the round cut-out of the 15" driver, take care not to bend the front baffle when assembling. You may find it useful to draw a line on the inside of the side panel using a long straight edge to ensure you keep the front baffle straight.

This is a critical stage in assembly, is is very important not to rush this. Take a good look at what you are doing before you attach panels.

Step 12:

Once you are confident everything is in the correct position, apply glue to all faces that are to be attached.

Push the front baffle firmly into place, and whilst checking the baffle remains straight, clamp the baffle to the side panel in two places, inside the round cut out, and inside the 8" horn cutout.

Before proceeding, double check everything fits snugly and there are no unexpected gaps. Its very hard to adjust anything after this stage if you get it wrong. Make sure you push down so that the baffle is sitting in the rebate in the top panel.

Step 13:

Start by pinning the front baffle to the brace and the divider, whilst pushing the front baffle firmly into place.

Before proceeding, check again that everything fits snugly and there are no gaps.

For step 14 you may find it useful to mark the outside of the side panel with a guide line 40mm in from the front edge. This is not essential, but this will make pinning the side panel to the front baffle easier, and help ensure you apply pins in the correct position.

Step 14:

Move on to the side panel and pin at intervals between the clamps. Once  the side panel is firmly fixed to the front baffle in a few places, you can remove the clamps and continue fixing the two panels together securely.

Take care around the 15" round cut out, its best to avoid pinning here at the narrowest point, just leave it for the glue to set and form the bond here.

Once all the other panels are secured, turn the cabinet around so that you can pin through the top panel into the front baffle.

Step 15:

You must now remove all the support spacers, as it will be impossible to get them out once the second side panel is fitted.

Before proceeding check the positioning of all the other panels. The divider shelf and brace on the exposed side should be flush with the front baffle, sand as necessary to ensure they line up.

At this point you still have good access to the inside of the cabinet, this is the perfect opportunity to run a thin bead of glue along the inside of any corners that may need it. If you've been applying this generously as you go along you may not need to do this. Use a slightly damp cloth to wipe up any excess glue.

Step 16:

We're getting close to finish, but don't rush - it's important to make sure the second side panel is fitted correctly, and as before, be careful with the front baffle to avoid bending it across the round cutout for the 15" cutout.

Apply generous beads of glue to all faces that will be fixed together. Place the side panel in position, pushing it firmly into place against the divider and brace, and then clamp it against the front baffle. Check carefully that everything lines up and there are no gaps between panels..

Step 17:

There is a little variation with any natural product such as wood. The kit is designed to fit together allowing for this, and providing you assemble in the order specified in these instructions  all the panels should fit snugly together,  leaving in some cases a slight lip (typically less than 1mm) on the top and bottom panels and the second side panel. This is intended to be sanded or planed off afterwards, and is a better option than having to fill gaps.

Before pinning the side panel, place the bottom panel in position - this will help ensure to align the the side panel in the correct position. In the picture the bottom panel is just held in place with light finger pressure. Start by fixing the rear panel to the side panel.

Step 18:

After fixing the rear panel to the side panel, manipulate the box the other way up so that you can pin the top panel into the second side panel - do not pin the bottom panel in place yet.

Leave the clamps in place between the side panel and front baffle whilst you are doing this.

Step 19:

Continue working around the box and pin the side panel to the front baffle, the internal divider and brace. Drawing guidelines will help with locating the pins. Again, keep the clamps in place until you have started pinning the side panel to the front baffle, and avoid pinning near the narrow part of the baffle.

Before proceeding to the final stage check all panels have been pinned and glued as appropriate.

Step 20:

There is just one panel left to finish the main assembly of the cabinet, as mentioned previously, there is sometimes some natural variation in wood, and it is also possible to assemble panels slightly out of alignment. Before fitting the last panel, check the corners and sand as appropriate to ensure a close fit.

Whilst you still have easy access to the inside of the cabinet, check all joints have appropriate glue. Either add a bead of glue, or wipe away excess as appropriate.

Step 21:

Apply a bead of glue and then pin the bottom panel into the rear, left and right panels.

The bottom panel is not connected to the front baffle due to the slot port.

Step 22: Finishing

The main cabinet is now assembled, just the finished left to do. If you've made it this far, hopefully you dont need any further instructions, but here's a quick summary of what we do:

1. Allow the glue to dry, and then use a belt sander (or similar) to smooth all joints.

2. Use non-solvented (water-based) wood filler to fill all screw holes or nail holes. Mix in a little wood glue with the filler to make it stronger.

3. Sand over all the filled areas.

4. Using a router and roundover bit, carefully go around all the edges of the cabinet. If you dont have a router, run a belt sander over the edges to smooth them off a little.

 5. Check the surfaces of the cabinet carefully to ensure they are free of dirt and dust, ready for painting. After sanding its a good idea to use a slightly damp cloth to wipe the surfaces, this helps remove fine particules of dust.
