The Acoustic Research AR-33BX is a floor-standing loudspeaker that was introduced by Acoustic Research in the 1970s. It is part of the legendary AR-3 Series that is known for its exceptional audio quality, and the AR-33BX is considered one of the best models in this series.The AR-33BX features a three-way system with two 12-inch woofers, one 8-inch midrange driver, and one 1-inch tweeter. The woofers are mounted facing inward to provide improved bass coupling, while the midrange driver is mounted in a separate enclosure to minimise interaction with the bass drivers. The tweeter is mounted in a separate waveguide enclosure to ensure precise high-frequency dispersion.The AR-33BX also features a unique cabinet design that employs dual elliptical enclosures, one for the woofers and one for the midrange driver, to eliminate resonance and deliver a clean, detailed sound. The bass enclosure is also rigidly braced and internally dampened to further reduce vibration and prevent colouration of the bass response.In terms of performance, the AR-33BX is known for its exceptional clarity, detail, and dynamic range. The bass is deep, tight, and well-controlled, and the midrange is smooth and natural. The highs are crisp and detailed, with excellent resolution of fine details. Overall, the AR-33BX is a true audiophile-grade loudspeaker that offers exceptional value for money.In summary, the Acoustic Research AR-33BX is a high-end floor-standing loudspeaker that features a unique three-way driver array, dual elliptical enclosures, and advanced cabinet design that results in exceptional audio quality.
