A ‘China Red’ finish for the LS3/5a model, fitted with a dedicated active stereo subwoofer system (AB3a), to mark the 75th anniversary (1949–2024) of two significant events: the launch of the famous BBC loudspeakers and the founding of the People’s Republic of China. The configuration is the same as the original Rogers AB1, where each subwoofer functions as a stand for the partnering LS3/5A. Each active subwoofer is fitted with a Class/B 50-watt mono amplifier and two Rogers LS3/5A bass drivers. The drivers are treated with a special resin to lower the resonance frequency and stiffen the Bextrene cone. Each amplifier is adjustable in terms of gain, frequency and phase response.
