DS18 PRO-FR8NEO 8" Neodymium Bullet Full-Range Loudspeaker 500 Watts 4-Ohm With Grill 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, we have more than 10 different models of Neo full range to accommodate any build. Highlights High powered aluminum voice coil backed by an intense neodymium magnet for more volume at the highest efficiency on the market. Beautiful DS18 design including a DS18 Tooled aluminum brushed accented basket and high quality terminals. Silver Bullet Resonator (tweeter) that effectively widens the higher range of your NEO bringing you a fuller range of frequencies to blast.
