The SB Acoustics SB16PFCR-4-COAX is a 2 way coaxial loudspeaker drive unit featuring a 6" paper composite cone midwoofer with a 1" centre mounted soft dome tweeter. You will need to design a suitable crossover for this item - the drive elements are well behaved so modelling is not difficult.
The tweeter is available as a spare part: SB14ST-C000-4 , it can be adapted to repair various other coaxial speakers that feature a 1" pole piece.
