Lowell IBOX-2 Large Volume Acoustic Backbox for Speaker Systems

The Lowell IBOX-2 is a high-capacity acoustic backbox designed for distributed speaker systems that demand top-quality sound reinforcement. It combines the advantages of a large metal enclosure with the acoustic features of a 3/4” plywood box. This allows a 12” speaker to work at its best loading level, enhancing the system's low-frequency response. Technical details include a welded 18-gauge steel unit with damping to reduce acoustical and mechanical resonance. It has a black finish, measures 23.75 in. x 18.00 in., with a depth of 8.06 in. and a volume of 2 cu.ft. The acoustical treatment includes a sound board and 1.5 in. batting. Mounting aids are 8-32 screw retaining U-clips and 1/4-20 forged eyebolts, and it's for screw-mount grilles. It's made in the U.S.A. with certified U.S. steel.

Using the Lowell IBOX-2 is straightforward. First, find a suitable location for your speaker system and place the backbox there. Attach the 12” speaker to the backbox, making sure it's properly seated. Use the 8-32 screw retaining U-clips and 1/4-20 forged eyebolts for mounting. For the grille, use the screw-mount method. When it comes to maintenance, keep the backbox clean by wiping it with a dry cloth. Avoid exposing it to extreme temperatures or moisture. Check the connections regularly to ensure the speaker is securely attached. If you notice any rattling or unusual noises, it might be a sign of loose parts, so check the screws and bolts. And since it's made of steel, watch out for any signs of rust and address them promptly.
