Martin Audio WPM Ground Stack Bar

The ASF20056 (long) and ASF20057 (short) are Martin Audio's ground stack bars for the WPM-GRIDt touring flying frame, letting a WPM Wavefront Precision Mini array be ground-stacked instead of flown. The bar sets the stack's splay and is compatible with both the WPM and MLA Mini ranges.

The two lengths cover different stack heights and cabinet counts, so the correct one is chosen to match the array being deployed.
