Page 6: Enclosure Assembly
Enclosure Assembly: First, before gluing anything, do a dry fit of the enclosure to familiarize yourself with the parts and assembly. This will also give you a chance to ensure that all pieces have been cut properly. Next, set the enclosure parts out on a flat level surface and ensure that all pieces are free of dust and debris. - Page 7 Apply a small bead of glue to the inside of the rabbeted edges and dadoes of all joining surfaces of the horizontal inner baffles, vertical inner baffles, back, and side panels. Then set in place applying enough pressure to ensure glue is spread through each joint (some glue squeeze-out can be expected).
- Page 8 Apply a small bead of glue to the front of the amp mounting panel. Keep at least 1-1/4” away from the oval shaped opening, as shown. Also apply a small bead to each outside edge of the amp mounting panel. Then set in place as shown, applying enough pressure to ensure glue is spread through each joint (some glue squeeze-out can be expected).
- Page 9 Finally apply clamps so that even pressure is applied to all glued surfaces. With just 4 clamps, begin by using 2 clamps to apply pressure to the top and bottom panels. Next, use the other 2 clamps to hold the side panels together. Then remove the first 2 clamps from the top and bottom and move them to squeeze the front and back together near two corners.

With a hot soldering iron, apply solder to the connections between components. Heat the junctions evenly and verify that the solder flows into the connection rather than forming a "blob" on the surface (cold joint). Cut 4 lengths of red/black speaker wire approximately 12" in length and strip 1/4" - 1/2" of insulation from one end of each wire and 1/2"... - Page 12 Install dual binding posts through the 2 holes in each vertical internal baffle from inside the main enclosure using 1 of the binding post spacers for each pair. On the inside of each sub-enclosure place the ring terminals attached to the 6" red/black speaker wires to the matching red and black binding posts and secure with the supplied nuts (no binding post spacer should be used inside the sub-enclosures).
- Page 13 Prepare the TPS3116D2 Class D 2.1 Bluetooth 4.0 Amplifier Board by removing all knobs, nuts, and washers. Place the acrylic amplifier mounting plate on the amplifier with the labels on the outside and secure using the supplied nuts (no washers) and tighten using 10 mm (13/32") wrench (do not over tighten), take care not to scratch the mounting plate.
- Page 14 Place the acrylic mounting plate onto the inside of the back panel of the enclosure in the matching recess. Secure into place using 4 x #8 x 1/2" Deep Thread Pan Head Screws and 4 x nylon washers through the pre-drilled holes in the mounting plate and back panel (do not over tighten). A screwdriver can be inserted through the tweeter hole in the front panel for easy access.
- Page 15 Insert the amplifier module/mounting plate assembly into the opening in the top of the enclosure and secure in place using 8 x #6 x 3/4" Deep Thread Pan Head Screws (do not over tighten). Connect the wires from the DC IN terminal from the amplifier board to the Dayton Audio LBB- 3 3 x 18650 Lithium Battery Charger Board/Module by stabbing the stripped ends of the red and black Consolidated 22 AWG Solid Hook-Up Wire into the connectors labeled VBAT + (red wire) and VBAT - (black wire) on the end of the battery charger board.

- Page 17 °, to worry about listening on axis. • For best bass response, and highest output, position the Blast Box near a wall or other rigid surface. • Lower the Sub Level and increase the Mid/High Level for maximum output capability.
- Page 18 • In situations where you will be listening primarily off-axis you can boost the Treble to improve extreme off-axis performance. • Familiarize yourself with all of the controls on the Blast Box to make adjustments on the fly, depending on the situation.
