Use this precision manufactured adapter Strap Kit to step down from the longer VLA601i speaker cabinet to the shorter VLA901i speaker cabinet. This adapter locks in just like the standard Strap Kits using the same interlocking features. Splay angles are also provided via the step bracket where VLA901i cabinets can be tight-packed up to the VLA601i cabinet or splayed out, up to 10 degrees. Attaching the VLA901i cabinet underneath the VLA601i cabinet provides additional near field coverage.
