The original Infinity woofer has been discontinued, all the specs and parameters were copied to ensure similar sound and exact physical fit. Original woofer impedance(Re: 3.9 ohm), our copy is also 3.9 ohms. The basket size and screw holes are identical, so you do not have to modify the cabinet at all. We had the surround changed from foam to rubber to improve the longevity. Rubber surrounds will also reduce cone break up and ensure low distortion.

– JBL J520, J520M, MR25 woofers and more. Part # P205G.
