Sundown Audio SA-6.5CX 6.5" Coaxial Speakers

120 watts RMS Silk dome tweeter Hybrid fiber cone Adjustable crossover - midrange and tweeter Cast aluminum frame Magnet ID shorting ring (midrange) Machined aluminum tweeter housing High-compliance rubber surround 2.75" DEPTH Sundown’s premiere sound quality separates, the SA-6.5CS is a marvel of design and top-tier components. The midrange features a high-quality cast aluminum basket, housing a cone with a carefully selected blend of paper and wool fibers. This design dampens any unwanted resonances for an incredibly smooth, detailed response. The surround is a high-compliance rubber, engineered to tame edge resonances within the cone. An FEA-optimized motor was designed in-house, and features a full 6mm one-way linear excursion - thanks to a carefully designed motor and extended pole piece. To increase thermal performance, the SA midrange features a vented magnetic gap and vented voice coil collar. The SA series silk dome tweeter matches the smooth sound of the midrange. A result of extensive testing, Sundown optimized the tweeter’s gap, dome material, lens, and chamber damping material. The results speak for themselves. The separates feature a 12 dB network centered at 3800 Hz, with high quality air core inductors and Mylar capacitors. Change the midrange low pass filter to your acoustic tastes from a 12dB, to 6dB, to a bypassed slope. The tweeter's response is also customizable, ranging from 0, to -3, to -6 dB levels. The SA separates were engineered for one, simple goal: to let you completely immerse yourself in the music. At any volume. For as long as you want.
