In one or more embodiments, speaker sub-assemblies with batched cones may be attached to each other by way of an adapter segment to create a dual-core speaker with batched cones. In one or more embodiments, speaker sub-assemblies with batched cones may be assembled in parallel, or linearly end-to-end.
