Martin Audio WLXGS manual Horizontal splays, For a smooth polar crossover

Horizontal splays

Splaying WLX/WLXGS arrays horizontally will widen their mid-bass coverage.

The following sketch shows an 8 wide x 3 high WLX/WLXGS array arranged in four symmetrical pairs for smooth mid-bass coverage.

WLX/WLXGS Wide		Horizontal coverage
(Splayed with	43Hz	86Hz	172Hz
Radius = width)
2	Wide	90º	60º
4	90º	60º	30º
8	60º	30º	36º
16	30º	36º	40º

Note that lower frequencies remain focussed when large arrays are used with large radii. Smaller systems with small radii will widen coverage at all frequencies but may cause cause low frequency build-up on thrust and island stages. Avoid this problem by augmenting small stage corner systems with WLXs placed along the stage apron.

For a smooth polar crossover:

Array the WLXs to match the curvature of the main clusters' low-mid or mid-bass section whenever possible but avoid making the front horizontal gaps greater than 200mm. Avoid large gaps between the main system and the WLXs whenever possible.
