Rare Acoustic Research AR-1W + JansZen 1-30 Electrostatic – Unique Mono / Centre-Channel System. A very rare piece of early high-end audio history. For sale is one Acoustic Research AR-1W woofer cabinet paired with one JansZen 1-30 electrostatic tweeter – the legendary combination that helped establish Acoustic Research and JansZen as pioneers of high-fidelity loudspeaker design in the 1950s. The AR-1W uses Acoustic Research’s groundbreaking acoustic-suspension principle and 12-inch woofer, designed by Edgar Villchur and his team. The AR-1/AR-1W was revolutionary for its ability to produce deep, exceptionally low-distortion bass from a relatively compact sealed enclosure. Its Alnico motor, lightweight cone and compliant suspension were years ahead of their time. At the top is the extraordinary JansZen 1-30 electrostatic array. Using a true push-pull electrostatic diaphragm, it was renowned for its exceptionally smooth, open and detailed midrange and treble. The 1-30 was specifically developed as an add-on high-frequency unit and became famous for being paired with the AR-1W. The two even appeared together in contemporary demonstrations and advertising. This is one of each, rather than a conventional stereo pair – which makes it particularly interesting for a collector. It would make a wonderfully quirky mono system for historic recordings, or an extraordinarily unusual centre-channel experiment in a vintage/modern hybrid system. The JansZen has been serviced and is working. It is a 117V unit, so a suitable step-down transformer is required; one can be included. These are exceptionally uncommon pieces and this is an opportunity to own a genuinely historic loudspeaker combination that represents one of the great innovations of the early high-fidelity era. Both units show their true 70+ year age with a few scratches and dents adding an honest patina, but are presentable. The Janszen 1-30 tweeter grill cloth could be replaced, but for originality I have not. Please see photos for condition. A unique piece for the serious vintage audio collector.

This pair of cabinets were my Dad’s. I had put wood preservative on them a few months ago. The cones were re-coned a few months ago. 1 sounds perfect, the other one needs to be pushed in to the cone and then is strong. I don’t know the problem, and I did not check both until after the re-coning. Voice coil is still intact as it has sound. The other high and mid range are good. Too heavy for me to move around. We’ll go over speakers when you come to look them over.
