Sundown Audio SA-6.5CS v.3

The SA component set starts out with its custom designed midrange driver. The mid features a high quality cast aluminum basket as its starting point; where many speakers in this category go with cheaper stamped steel frames. The motor was FEA optimized in-house to increase linear excursion and features a full 6mm one-way linear excursion thanks to a carefully designed motor and extended pole piece. Sundown Audio also considered thermal performance in the design with the SA mid featuring a vented magnetic gap and a vented voice coil collar. The 60-watt per side power rating on the SA mid is derived from a full 8-hour test on pink noise (full bandwidth down to 20 Hz) -- so when crossed over on the bottom-end this figure ends up being VERY conservative. Most customers use 100+ watt RMS amplifiers on the SA sets.
