MW AUDIO Model # MW-5083

Boston Acoustics A60 series II woofer copy.  Outside diameter is 8.94".  It is also a good replacement for the A70 series II. 

***The A60 series I woofer is similar, but the screw hole mounting is completely different and the outside diameter is 8.21".  This woofer will NOT fit A60 series I speakers, only series II.  Your A60 speaker will only say if it is series II on the back of the cabinet by the terminal cup.  If it just says A60 with nothing after it then you have series I.

Price is for one woofer.  Please change quantity to order more.

The original A60 series 2 woofer has been discontinued from Boston Acoustics for years now. This woofer features a polypropylene cone with polyether foam surround. All the specs and parameters were copied to ensure similar sound and physical fit. Same impedance (4 ohms), basket size and screw holes, so you do not have to modify the cabinet at all.

*The Boston A60 series II speakers say 8 ohms on the back of the cabinet, but the DC Resistance on the woofers are around 4 ohms.
