Up for sale is a pair of Acoustic Research AR-11b three-way loudspeakers in great working condition. These are the classic late-70s successors to the legendary AR-3a, and this pair includes the rare, early-production YELLOW-CAPPED (yellow dome) tweeters – the version collectors specifically seek out, widely considered the best-sounding tweeter AR fitted to this series before switching to the later black domes. Fully functional – all drivers tested and working properly on both speakers. Woofers FRESHLY REFOAMED – new surrounds, ready for decades of service. Rare yellow-capped 3/4 dome tweeters, both original and working. Cabinets structurally solid and in great physical shape – no loose joints, chips, or damage. Finish needs refinishing/restoration – wear visible in photos; a great candidate for an easy veneer refresh. Original foam grilles were replaced at some point – current replacement grilles are shown in photos (the original AR foam grilles from this era commonly deteriorated and are rarely found intact). Please review all photos carefully – they are of the actual speakers and part of this description. Type: 3-way, 3-driver acoustic suspension loudspeaker. Woofer: 12 acoustic suspension (freshly refoamed). Midrange: 1.5 hemispherical dome. Tweeter: 3/4 hemispherical dome (rare yellow-cap version). Frequency Response: 27 Hz – 30 kHz. Crossover Points: 525 Hz / 5,000 Hz. Impedance: 4 ohms. Sensitivity: 86 dB (1W/1m). Recommended Amplifier Power: 25-150+ watts per channel. Dimensions (each): 25″ H x 13.9″ W x 10.75 D. Weight (each): approx. Acoustic Research invented the acoustic suspension woofer and the dome tweeter, and the AR-11 line represents the refinement of both. The AR-11b uses an improved version of the 12″ woofer that started it all, paired with the famous hemispherical dome midrange from the AR-3a and AR’s improved 3/4″ dome tweeter. The result is deep, flat, honest bass and the smooth, wide-dispersion top end AR was famous for. The early yellow-dome tweeters found on this pair are increasingly hard to find in working condition – many surviving AR-11s have had them replaced with later or aftermarket domes. These are all original. With the woofers freshly refoamed and everything working as it should, these are ready to play – or refinish the cabinets and have a truly stunning pair of classic American loudspeakers. These are large, heavy speakers (50 lbs each) – they will be professionally double-boxed and fully insured. Photos are of the actual items and are part of the item description.
