Enclosure Assembly:

1. First, take the back panel and lay out and drill holes required for the Binding Posts (P) included in your kit.
2. Next, set the enclosure parts out on a flat level surface and ensure that all pieces are free of dust and debris.
3. With the Back Panel (M) lying flat, glue all mating surfaces of the Bottom Panel (J) and one Side Panel (L) and secure them to the back panel with clamps so that even pressure is applied to all glued surfaces. Using a damp rag or paper towel wipe away any glue squeeze-out on the outside of the enclosure and inside the rabbeted edge (excess glue on the inside is fine). Allow to dry according to the glue manufacturer’s recommendations and remove clamps.
4. Next, glue all mating surfaces of the Top Panel (J) and the other Side Panel (L) and secure them in place with clamps so that even pressure is applied to all glued surfaces. Using a damp rag or paper towel wipe away any glue squeeze-out on the outside of the enclosure (excess glue on the inside is fine). Allow to dry according to the glue manufacturer’s recommendations and remove clamps.
5. Finally, apply a thin layer of glue to the front edge of the enclosure. Set the Front Baffle (K) in place on the glued edge. While ensuring all edges are even and square, position clamps to apply even pressure to all glued surfaces. Wipe away any glue squeeze-out on the outside of the enclosure. At this time double check that all edges are even and square (this cannot be adjusted once the glue is dry). Allow to dry according to the glue manufacturer’s recommendations and remove clamps.
6. Sand and finish enclosure to your liking. See our web page for examples.

Crossover assembly

Point-to-point wiring diagram

7. Arrange the components as illustrated in the point-to-point wiring diagram above so the leads can be connected together as shown. Take careful note of the component type and the value of the component. (The crossover schematic is provided at the end of this assembly guide.) If you would like, the crossover can be mounted to a 3″ x 5″ board to make handling it a little easier.
8. Connect the leads of the components as shown in the diagram by twisting them together or creating interlocking “hooks” with the leads. Double check your layout to ensure all components are in the proper location and connections are correct.
9. With a hot soldering iron, apply solder to the connections between components. Heat the junction evenly and verify that the solder flows into the connection rather than forming a “blob” on the surface (cold joint).
10. Cut two lengths of 2-Conductor Speaker Wire (N) approximately 10″-16″ in length, then solder them at the outputs of the crossover network as labeled “woofer” and “tweeter” in the schematic so that the marked polarity of the wire matches the driver polarity shown in the schematic. Label each wire “woofer” or “tweeter” corresponding to the schematic.
11. Finally, cut one length of 2-Conductor Speaker Wire (N) approximately 6″-10″ in length. Solder this wire to the “input” connections of the crossover network as shown in the schematic so that the marked polarity of the wire matches the input polarity in the schematic. Label the length of wire “Input”.
    Note: You may find it easier to solder all the negative (-) connections at once. This connection may require a lot of heat, so take your time and be patient when making this connection.

Product Usage Instructions

If any parts are missing or damaged please contact the customer service department at 1-800-338-0531. Note: Crossover components may be substituted with parts of equal of higher quality depending on stock.
2. If you purchased the Components Only version of the C-note, find detailed drawing of the enclosure at the end of the manual and begin following these instructions from step #7.
3. Take the back panel and lay out and drill holes required for the Binding Posts (P) included in your kit.
4. Set the enclosure parts out on a flat level surface and ensure that all pieces are free of dust and debris.
5. With the Back Panel (M) lying flat, glue all mating surfaces of the Bottom Panel (J) and one Side Panel (L) and secure them to the back panel with clamps so that even pressure is applied to all glued surfaces.

Allow to dry according to the glue manufacturer’s recommendations and remove clamps.
7. Finally, cut one length of 2-Conductor Speaker Wire (N) approximately 6″-10″ in length. Solder this wire to the “input” connections of the crossover network as shown in the schematic so that the marked polarity of the wire matches the input polarity in the schematic. Label the length of wire “Input”.
   Note: You may find it easier to solder all the negative (-) connections at once. This connection may require a lot of heat, so take your time and be patient when making this connection.

Final Assembly:

8. Insert crossover through woofer hole and glue crossover to the bottom of the enclosure (polyurethane glue, high temperature hot glue gun, or epoxy is recommended). Ensure all crossover components are securely held in place to prevent rattles.
9. Port installation is simple. Slide the adjustable end of the 1-3/8″ ID Adjustable Port Tube (A) onto the flanged end and glue in place at the desired length using any glue that is acceptable for use on plastic (super glue, plastic cement, hot glue, etc…). Insert the assembled port into the enclosure and screw into place using 4 x #6 x 3/4″ Pan Head Screws (O). The recommended port length is 7″. The length can be adjusted to your taste, a shorter port will result in slightly less bottom end with a tighter punch.
10. Install the Binding Posts (P), and connect the input wires from the crossover while observing polarity (positive = red, negative = black)
11. Connect tweeter wires to the terminals on the ND25FW-4 1″ Soft Dome Neodymium Tweeter (B) while observing polarity (positive = wide terminal, negative = narrow terminal) and set tweeter in place. Using a screwdriver, secure tweeter with 4 x #6 x 3/4″ Pan Head Screws (O) just until tight being careful not to strip out the holes (a power drill is not recommended).
12. Connect woofer wires to the terminals on the DSA135-8 5″ Designer Series Aluminum Cone Woofer (C) while observing polarity and set woofer in place. Using a screwdriver, secure woofer with #6 x 3/4″ Pan Head Screws (O) just until tight being careful not to strip out the holes (a power drill is not recommended).
13. You are now ready to enjoy your finished C-Note speakers.
