DS18 6.5" Mid Bass Loudspeaker 4 Ohm Pro-Neo6
DS18 amassed a wealth of experience in manufacturing the most elegant neodymium midranges for those seeking simple perfection. Neodymium magnets provide a higher magnetic flux density in the air gap, which generates a much greater action force in the voice coil. For this reason, Neo magnets have the strongest permanent magnets of all the commercially available speakers. Ranging in sizes, mounting depths, and frequency responses, they have more than 10 different models of Neo midranges to accommodate any build.
