By taking the Be-10 and integrating a second woofer using Usher’s proprietary configuration, the BE-20 Diamond DMD possesses an ease and authority in ultra low bass reproduction that’s difficult to match even by speaker systems several times larger in size. This is a speaker for those seeking the final word in ultra low bass reproduction and refinement through the entire frequency range in a large listening room.
