Description: MW AUDIO Model # MW-5060-4Boston Acoustics A40 series I woofer copy. The outside diameter is 6.57". The A40 series II woofer is similar, but the screw hole mounting is completely different and the outside diameter is 6.875". These woofers will still fit with slight modification for the series II. Your A40 speaker will only say if it is series II on the back of the cabinet by the terminal cup. If it just says A40 with nothing after it then you have series I.Price is for one woofer. Please change quantity to order more.The original A40 series 1 woofers has been discontinued from Boston Acoustics, so we had these custom made by a manufacture right here in the USA. Yes that is right, these are not made overseas. All the specs and parameters were copied to ensure similar sound and exact physical fit (series I ONLY). Same impedance (Re: 3.5 ohm), basket size and screw holes, so you do not have to modify the cabinet at all for the series I. The Boston A40 speakers say 8 ohms on the back of the cabinet, but the DC Resistance on the woofers are around 3.5 ohms.Made and Designed in MPLS, MN USA.Features a polypropylene cone with santoprene rubber surround.Dimensions: 6.57" outside diameter 5.59" cutout diameter 2.67" mounting depthSpecifications and Small Signal Parameters Voice Coil Impedance:4ohm Rated Frequency Response:40 - 5kHz Sensitivity:89dB SPL (Average 500 - 2.5 kHz, 2.83V, 1 meter)Rated Power:40watts Program Power:80watts Magnet Weight:340gr (12 oz) Fo:45Hz Re:3.5ohm Qts:0.51 Qms:7.84 Qes:0.54 Vas:31liters Xmax:3.8mm No:.49% All packages are insured with tracking.
