DIY How to Build a Speaker Box Isolation Cabinet

Speaker isolation cabinets are designed to acoustically detach electric guitar speakers and microphones from surrounding spaces for recording purposes. Given that electric guitar speakers are played very loud to achieve that characteristic "crunchy" sound from the instrument, hearing damage or general annoyance can occur. Isolating the cabinet and mike allows these volumes to be achieved without running these risks.

  1. 1

    Cut the panels of the box large enough to accommodate the electric guitar speaker. Remember that the box must also fit a microphone on a small stand in front of the speaker.

  2. 2

    Drill a hole 1/4 inch from the edges of each panel on the facing side, 3-to-6 inches apart.

  3. 3

    Screw the panel comprising the isolation box together, using the 2 inch wood screws. Do not attach the lid at this time.

  4. 4

    Flip the box over, with the bottom facing up. Screw the four casters to the bottom of the box 1 inch from the corners of the enclosure. Turn the box back over onto the casters.

  5. 5

    Cut the acoustic foam to fit the inside of the box. Spray a thin layer of adhesive on the back of each acoustic panel and the inside of the enclosure.

  6. 6

    Press the foam pieces to the inside of the enclosure. The pieces will cover the four sides and bottom of the enclosure.

  7. 7

    Cut additional foam to fit under the lid of the box. Cut the pieces so that a 1 inch border exists around the lower edge of the lid, to allow for proper sealing.

  8. 8

    Cut pieces of weatherstripping to fit along the upper edges of the enclosure. Peel off the adhesive backing of the weatherstripping and press it into place.

  9. 9

    Screw the hinges to the top of the lid, along the back edge. The hinges should be placed 1-to-2 inches from the sides of the lid. Lay the lid on top of the box. Screw the other side of the hinges to the upper rear section of the box.

  10. 10

    Screw the handle to the top of the lid, 1-to-2 inches from the front edge and dead centre.
