Myslím, že se pleteš - i koncentrický spadá pod koaxiální měniče.
Něco z googlu:
In 1988, KEF introduced a coaxial loudspeaker of their own design and manufacture, called the "Uni-Q", for their high fidelity loudspeakers. Tannoy has also produced coaxial loudspeakers, called the "Dual Concentric", which are featured in their high fidelity loudspeakers. Cabasse has since been able to design and manufacture the "4-way Concentric QC-55 Driver" as seen in their flagship model - La Sphère.
