Coaxial refers to the application of having the tweeter mounted centrally in the same driver mechanism as the mid-woofer. This offers a convenient solution for a compact box design utilizing a smaller facia without the additional tweeter mounting. Being mounted "Inside" the woofer also improves acoustic performance with optimal time delay between the drivers and offer the advantages of a single point source for a consistent acoustic center and a symmetrical dispersion pattern. SB Acoustics coaxial drivers require an external crossover network. This is to be custom developed by the designer depending on the extent of the application and the designers preferences in driver matching, etc. See datasheet ~3KHz 12dB/Octave. Read / Show More
