Portable bass speakers are designed to provide good bass response and portability. These units are usually easy to connect to an audio head unit. Portable units are necessary when the speaker does not stay in one spot over a predetermined time. Concert speakers---or any speaker used in a changing environment---is usually portable. Portable bass speakers are not difficult to build because of the growing popularity of pre-built enclosures. These enclosures mean not worrying about doing the complex sound calculations; they are already done for you. You just have to supply the speaker.

Things you need
- 1 Prebuilt bass speaker enclosure (12-inch opening)
- 1 12-inch subwoofer
- Casters (equipped with locks)
- Red and black speaker wire
- Wire cutters
- Wire strippers
- RCA plug socket with screw terminals
Set the speaker enclosure on a table. Turn it upside down so that the bottom of the enclosure is facing up. Mount one caster on the right rear corner and mount a second caster on the left rear corner of the bottom of the enclosure. Repeat this for the front two corners. This allows the enclosure to roll when moving it around. These casters should be the ones with locking brakes.
Lay the enclosure down so that the speaker opening is facing up. Lay the subwoofer face down and cut one 24-inch piece of speaker wire. Strip 1/2 inch of insulation off of both ends. Connect one end of the positive wire to the positive terminal of the speaker. Connect the other end to the centre screw terminal of the RCA Adapter.
Connect one end of the black wire to the negative terminal of the subwoofer, and then connect the other end of the black wire to the outside screw terminal on the RCA plug adaptor. If a hole is not already present, drill a small hole for the RCA plug adaptor. Secure the adaptor to the enclosure using screws. The adaptor should be turned so that the RCA plugs are pointed outside of the enclosure and the screw terminals are pointed inside the enclosure.
Push the wires into the enclosure and set the 12-inch subwoofer in the speaker opening face up. Secure the speaker to the enclosure using screws.
Turn the stereo on and enjoy the deep subwoofer sounds.
