Construction hints:

The front vented box size is 100cm high, 23 cm wide and 36 cm deep. Assembly requires a well lit, work around, flat space with a clean non abrasive top with a minimum of 130 cm by 60 cm to accommodate clamping for more than 4 hours after gluing. Air Temperature should be over 10 degrees.

The tight jointing makes possible a complete dry fix. Build up on a side panel laid on the two belt clamps. This allows for the sequence of gluing the parts together to be noted and the use of clamps.

The top and bottom and back panel support frame are used to square up the box and observe the full insertion of panels into the grooves.

Metal inserts will need screwing into that frame and the base (for spikes)

The back can be inserted to help maintain squareness under clamping. Minimal glue is required, applied to the groove base and inside its inner wall.  The front panel is edge clamped in three places and the glue squeezed out easily wiped off with a damp cloth.

A careful check on the top and bottom corners may reveal slight movement on clamping- so tap (using a cardboard pad to reduce bruising) and adjust for visibly perfect corners.

The gasket seal strip is fitted with no gaps avoiding bolt holes on the back framing. More is added to the back of the holed divider and through the driver access hole onto the dividers front edge against which the magnet of the driver will sit.

Before bolting the Pluvia secure its colour coded wires onto the correct driver terminals and squeeze the push on spade connectors with pliers if needed to get a firm fix.

When fitting the drivers ensure the ‘M’ on the rim is displayed nicely. I protected the vulnerable rubber suspension and cones in case of slippage by covering with my hand as we used the hex key to drive the bolts firmly cutting their own holes. Do not over tighten but aim for evenness – the bolt heads should appear at similar heights in their ‘wells’.

The high quality cable sockets are indented to fit with a careful sequence of mounting hardware.

The wadding is itch free and 400gm is supplied but we started with 200g teased out to fill the lower half of the four cavities. This gave an exciting presentation if a little ragged. Experimentation did change this to a final 370gm in the top two thirds (some behind the driver, and not near the vent). The felted pads offer further damping behind the driver if wished though we resisted possible over damping and did not use them. Tighten the backs bolts evenly. If the box is laid on its front the driver is protected from touching the surface by raised parts of its rim.
