"The DS18 PRO-ZT6 6.5"" Water-Resistant Midrange Loudspeaker with Bullet Tweeter and Grill serves up 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. That gives neodymium speakers the strongest permanent magnets of all commercially available models. The aluminum-brushed accented basket, high-quality terminals, and high-power aluminum voice coil backed by an intense neodymium magnet provide greater volume at exceptionally high efficiency. A built-in bullet tweeter effectively widens the higher range of your neodymium speaker, bringing you a greater range of frequencies to blast. RMS Power: 225W. Max Power: 450W. Mfrs. 2-year warranty.
