Page 2: Assembly Manual
Assembly manual You will need: • Phillips head screwdriver • Woodworking glue • Damp cloth • Good quality masking tape • Ratchet tie down strap (optional) • Brick or other weight (optional) Preparation Lay the contents of the box out and check you have everything you need to complete the kit (see parts list on back page). - Page 3 Assembly manual Masking tape We recommend avoiding cheap masking tape, which tends to break when applied under tension. Lay out the rear panel and apply masking tape as shown. Flip over the panel to expose the mitres. Carefully position sides, top and bottom panels. Press the panels firmly along each join so that the masking tape on the other side adheres to the MDF.
- Page 4 Assembly manual Apply a glue bead to all four joins between the rear and adjacent panels. This first bead of glue should be applied to the bottom of the mitre. Then apply a second bead in the middle of the mitre.
- Page 5 Assembly manual Confirm that the glue adequately covers the entire surface of the joins by folding up each pair of panels to form a join. Check the glue covers the entire surface of the join. Add more glue where necessary. Fold up the first three panels as shown above. Wipe excess glue then firmly press the panels together as you hold them in place with masking tape.
- Page 6 Assembly manual Tweeter magnet cutout In the photo above and below you can see the brace with the tweeter magnet cutout facing the baffle, which is yet to be inserted. Note in the photo below that the brace is oriented to place the cutout towards the top of the enclosure.
- Page 7 Assembly manual Apply one thick glue bead to the mitres on the front baffle. Alternatively, you may prefer tro use a zig zag pattern. Confirm the amount of glue by pressing into position. The entire join should be covered in glue – apply more glue where necessary. Now press the baffle firmly into place.
- Page 8 Assembly manual Clamping Due to the brace that is used, we recommend at least two F clamps which are large enough to clamp across the height (greater than 220mm). Six or more F clamps in total are recommended, as shown above. Strapping The use of two ratchet straps avoids the necessity of purchasing larger and more expensive F clamps.
- Page 9 Assembly manual Drying time Typical wood glues can achieve moderate strength in as little as 30 minutes. If you are using PVA glue then a good indicator that it has set is the transparency. PVA becomes transparent once set. Ideally it’s best to leave the enclosure clamped over night before moving on to assembly or finishing.

Page 10: Installing The Crossover Board
Assembly manual Installing the crossover board There are three sets of cables: • Input terminals: located near the larger inductor on the end of the board. • Tweeter output: easily identified by the white cable (HI+ HI -) • Woofer output: black cable next to the tweeter outputs (LOW+ LOW-) The crossover is fixed in place with 4 short button head self tapping screws. -
Page 11: Installing Terminals
Assembly manual As shown above, driver cutouts provide access to fix the passive crossover board in place. Using the shorter screws, fix the board in place with a Phillips head screw driver. Avoid over tightening. Ensure the board is oriented so the inputs with the shortest cable pair are near the terminal cut out. - Page 12 Assembly manual C6S section diagram Acoustic lining The acoustic lining provided with the kit covers all internal cabinet walls. Each of the smaller pieces (A) cover the side walls. The larger pieces (B) are folded into a U shape to cover top, bottom and rear walls, when the speaker is horizontally oriented as shown on the cover photo.

Page 13: Installing Drivers
Assembly manual To insert the lining, roll it up and insert through one of the woofer cutouts. No adhesive is necessary to keep the lining in place. Installing drivers We recommend using a Phillips head screwdriver, as some powered drivers are more likely to cause damage if the head slips off the screw head. - Page 14 Assembly manual Tweeter The tweeter must be installed first as the woofer flanges overlap. Find the white wire loom for the tweeter and push the connectors onto the driver tabs. Caution: tweeter terminals are fragile – observe instructions on the previous page about how to safely connect the cable without causing damage Insert the provided screws into position and tighten with a Phillips head screwdriver as shown below.
- Page 15 Assembly manual Woofers Find the white wire loom for each woofer and push the connectors onto the driver tabs. Caution: Observe instructions on the previous page about how to safely connect the cable without causing damage. Insert the provided screws into position and tighten with a Phillips head screwdriver as shown below.

Page 16: Grille Assembly
Assembly manual Now press both ports into position. No glue is necessary as the cutouts are precisely machined for a tight fit. Grille assembly Masking On the backside of the grille, you will notice a cut line inset from the edges. This cut line defines the area where the cloth will be glued to the frame. - Page 17 Assembly manual When you’ve finished spraying, turn the can upside down and spray briefly until you notice the amount of spray reduces. Usually after about one second, the paint stops but the solvent continues. This cleans out the nozzle and avoids blocking next time you want to continue using it.
- Page 18 Assembly manual Press the cloth onto the opposite edge. Above you can see the wrinkles across the grille which indicate sufficient tension has been applied. Again, stop short of the corners. Now press the grille cloth to the frame on the third side. Then finally, press the cloth to the remaining side of the frame.

Page 19: Wrinkle Free Corners
Assembly manual Wrinkle free corners The biggest challenge in assembling a grille is the corners. If not done correctly, these will bunch up. With a little care, you can avoid this problem and get a professional looking grille. Gather the fabric at the corners with both hands, as shown above. Pull the cloth at a 45 degree angle to each edge, stretching the fabric to eliminate as many wrinkles as possible. - Page 20 Assembly manual Trim the cloth Now you can use your thumbnail to find the cut line. Pressing your nail into the trench, score all the way around. This helps to confirm that you’ve effectively avoided wrinkles. Then with a sharp blade, slowly and carefully cut away the grille cloth, using the trench as a guide. Tips for a better cut: •...
