The original T830 & T1000 woofers have 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 T830 speaker says 8 ohms on the back of the cabinet, but the DC Resistance on the woofers are around 4 ohms.
