Sundown Audio SD3 Series Subwoofers
Shallow Mount Subs Available in 8″, 10″ and 12″
The SD-3 series truly is a world-class sound quality woofer with low mounting depth, small box requirements, and a reasonable price. This line features an under-hung motor topology – this means that the voice coil is shorter than the top plate so the amount of winding in the gap doesn’t change at all over the center portion of stroke – in this case featuring a 1” thick top plate and ½” long 8-layer copper voice coil. This allows for 14.5mm linear excursion one-way while maintaining an extremely flat BL curve. The large inverted rubber surround & high-stroke spider also allow for a very even compliance curve over the full range allowed by the SD-3 series.
