Infinity Reference 123W (INFSUBRF123W)

Infinity Reference subwoofers deliver deep powerful bass that will take your system to the next level. Using our proprietary cone design and high roll surrounds, they are extremely efficient and require less power to deliver the goods. The Infinity REFERENCE subwoofers are also happy in both sealed and bandpass box configurations, delivering powerful, punchy and accurate bass in all. They also feature SSI (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance, 2 or 4 ohms for your chosen amplifier and overall system layout.
