The port may have to be placed along the back wall facing the side. Place a brace between the subs about 4 inches wide on the inside. Make sure that the end of the port “inside the box” is at least the same distance away from the back wall as the port diameter. lf port is 4″ round 4.5″ from wall

DIMENSIONS

Attention:

• Box sizes account for driver and port displacement
• For higher SPL shortning the port length 3 in. will rise frequency +/- 5 Hz
• Box specifications are internal. for external dimensions add the width of the box material to these dimensions.
• A square port (slot) is prefered in high power applications for less vent noise.
• Port area = width x height
• For dual speaker, double the volume and the number of ports but keep the same length.
• if possible use a divided box.
• If a commom chamber box is to be used, internal bracing is highly recommended
• Please contact Massive Audio for custom applications.
