Product Research


Product Overview: The Boston Acoustic SPG555-VC2 is a 2Ω replacement voice coil assembly for use with the Boston Acoustic SPG555 subwoofer. It is not a stand alone driver.

Installation: Although the voice coil is round, it has a notch and will only seat flush with the cone one way. This ensures the voice coil leads are properly aligned.
