[QUOTE="Popwarhomie, post: 8720731, member: 619389"] The SD-4 is an SQ woofer. "The SD-4 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 all new “W” surround design and newly tooled spider work together to create a flat “center” compliance curve which quickly turns progressively stiffer past the linear limits of the motor. This was heavily optimized in 3D computer simulations. This makes the SD-4 significantly more mechanically rugged than the previous generation. To top off distortion reduction features the SD-4 features a shorting ring around the bottom of the pole-piece to even out the LE curve." [/QUOTE]
