The driver under test in this Test bench is the SDx10 home audio woofer from Creative Sound Solutions (CSS) Audio, using XBL^2 dual gap motor technology licensed from inventor Dan Wiggins. The CSS SDx10 also has a well-appointed feature set that includes a very stiff coated black paper/carbon fiber blended composite cone with a convex black hard paper dust cap, NBR surround, and semi-progressive cloth spider. All this is driven by a (2.4" six-layer voice coil with two 12mm thick ferrite magnets sandwiched between a thick XBL-configured front plate and black-plated thick T-yoke.

This Test Bench article addresses an interesting home audio tweeter from Creative Sound Solutions (CSS). The company sent Voice Coil its latest high-end tweeter, the LD25X, a special driver with a unique dual-gap patented XBL2 motor. CSS licenses the XBL2 technology from inventor Dan Wiggins for two of their woofers and for the LD25X tweeter. The XBL2 motor features a short voice coil traveling between two gaps, allowing for a higher Xmax than most conventional motors can provide. The LD25X tweeter features a 25mm silk dome diaphragm and flat silk surround, in a 73 mm diameter six screw cast-aluminum faceplate anodized semi-flat black. This article was originally published in Voice Coil, July 2020.
