About the Stadium III
The Stadium III is a substantial subwoofer, weighing 110 pounds and measuring 23 x 22 x 15 inches. It is finished in a beautiful cherry veneer, providing a premium aesthetic. Inside, it houses a 200-watt MOSFET amplifier with a self-limiter to prevent overloading. The subwoofer uses a downward-firing long-throw 10-inch heavy-duty driver. The enclosure employs REL's proprietary Acoustic Resistive Matrix (ARM) loading method, which enhances bass response by dividing the enclosure into separate cavities that vent in a controlled manner. This design allows for smoother and more extended bass, reportedly extending down to 16 Hz. The Stadium III offers flexibility in setup, with coarse and fine gain adjustments and a range of crossover points from 24Hz to 106Hz. It includes multiple input options, such as low-level RCA inputs, balanced XLR inputs, and a unique unbalanced input via a Neutrik Speakon connector, which allows direct connection from the loudspeaker terminals of an amplifier.
