acoustic revive AR-BWA-4 Bi-Wire Adapter for Speakers Set of 2 Rhodium-Plated Brass Cryogenic Treatment for Sound Quality Improvement

---------------------------------------------------------------------- This bi-wire adapter improves sound quality by reducing the back electromotive force (EMF) generated at the terminals of speaker systems. Using jumpers with bi-wiring compatible speakers negates the benefits of bi-wiring, as the effects of back EMF and uneven cable length degrade sound quality and phase characteristics. The purpose of the BWA-4 is to eliminate jumpers and distribute the signal evenly to the low-frequency and high-frequency speaker terminals, eliminating the effects of back EMF and achieving accurate phase characteristics. Distortion and muddiness are dramatically reduced, resulting in transparency, high resolution, and accurate sound image localization. It features an innovative structure with mirror-polished brass plated with silver and rhodium, then subjected to ultra-low temperature treatment at -196°C to maximize conductivity, and further enhanced with a duralumin cap for vibration damping. The ultimate conductivity and vibration damping effect not only eliminate conductivity degradation but also actively improve sound quality. Y-lug cables can also be connected to the input. Unlike expensive jumper wires, this allows for a true quality improvement. To prevent sound quality degradation caused by inserting an adapter in the speaker cable, the BWA-4 incorporates measures to maximize conductivity. The material used is highly conductive lead-free brass with rhodium plating, a secure cable fixing method using gold-plated double screws that do not degrade conductivity like soldering or crimping, and further improved conductivity through ultra-low temperature treatment at -196°C. The BWA-4 comes with insulating tubing to prevent short circuits caused by contact between the positive and negative terminals. If the positive and negative terminals are too close together and there is a risk of contact, be sure to cover them with the insulating tubing before use. The BWA-4 utilizes a 2017S aerospace-grade aluminum alloy cap, which, combined with the brass body, creates a vibration damping effect through the use of dissimilar metals. This vibration damping structure allows for rapid attenuation of vibrations transmitted through speaker terminals and speaker cables, further improving sound quality. ●Input side cable insertion hole: Inner diameter Φ4.3mm ●Output side cable insertion hole: Inner diameter Φ5.9mm ●Y-lugs can also be attached to the input side (Y-lug inner diameter Φ8mm or more)
