View →Supplying parts at trade level
Parts are supplied to distributors, repair businesses and speaker assemblers. Because a diaphragm or voice coil must match the driver it repairs — voice-coil diameter, material and impedance — ask the sales team to confirm the matching part number against your driver's model before you order, and ask them to confirm the minimum order quantity for the part in the quotation.
