Description

Wall-mounted speaker coverage with a separate subwoofer for a planned gym installation

This gym sound package brings together four JBL Control 28-1 speakers, one JBL JRX218 subwoofer, two Crown XLS 1002 amplifiers and one Daewoo DAM 04BT mixer. The separate components allow speaker placement and amplification to be planned around the training floor.

The Control 28-1 combines an 8-inch woofer and 1-inch high-frequency driver with an included InvisiBall wall-mounting system. Final speaker wiring, subwoofer amplification, crossover settings and signal routing must be designed for the installation.

Speaker loads, amplifier assignments, protective filtering and subwoofer crossover settings require installer confirmation before operation.
