PORTED ENCLOSURE

Building a Ported Enclosure:

1.Build a ported enclosure with internal dimensions of LxWxD as specified for your woofer (See recommended enclosures for your woofer). Use 3/4” thick MDF for the enclosure. Be sure to use wood glue and silicone at all joints to ensure your enclosure is sealed properly. Air leaks will affect the performance of your subwoofer, even in a ported enclosure.

2.Using the supplied template, trace the appropriate circle and mounting hole pattern for your PowerClass C2 subwoofer on the baffle board. Be sure to offset the woofer to one side to leave room for the port in the baffle. (See Diagram)

3.Cut the speaker and port holes from the baffle board with a router, using a guide or template whenever possible. Use a jig saw only if a router is not available.

4.Locate the port material that you are going to use, and cut to length. When installing the port, make sure you have a clearance of at least one port diameter from the end of the port to the inside wall of the box. Round over the inside edges of both ends of the port with a router or file to minimize port noise.

5.Place the woofer into the hole which you have cut in the baffle to check the fit.

6.Run an appropriate length of wire into the box, leaving enough to comfortably install the wires to the woofer terminals before placing the speaker into its mounting hole. Use a terminal cup whenever possible.

7.Vacuum out any wood shavings and dust from the inside of the enclosure. (Failure to do so may void your warranty.) Line the enclosure with a polyester fiberfill blanket or fiberglass insulation about 1” thick.

8.Connect the wires to the woofer observing the proper polarity, positive and negative terminals. Strip away the insulation of the wire about a 1/4" and install the wires into the terminal posts

9.Once the box is complete, it's time to connect the speaker wire coming from the subwoofer enclosure to your amplifier. Check that you use the proper wire for consistent polarity, positive and negative. (Refer to your amplifier owner’s manual.)

10.Finally, sit back and enjoy the incredible enhancement your new PowerClass C2 subwoofer brings to your audio system.
