The Infinity IRS Beta is a high-end loudspeaker system designed to deliver exceptional sound quality and detailed soundstaging. It features a complex driver array that includes four 12-inch woofers, two L-EMIM mid-bass drivers, one EMIM midrange driver, and two EMIM/EMIT tweeters, with one firing forward and the other backward to enhance ambient effects. The system operates at a nominal impedance of 4 ohms and is capable of handling a wide frequency range from 15 Hz to 45 kHz ± 2 dB. The recommended power handling is between 150W to 500W for the low band and 75W to 300W for the mid-high band per channel. The IRS Beta's design requires amplifiers that can deliver full power into a 4-ohm load with stability across all audio frequencies.
