Line array 線陣列
A column of loudspeaker elements hung close together so they behave as one long source, throwing further and covering more evenly front to back than a stack of separate boxes. Coverage is set by splay angles between elements, calculated in the manufacturer prediction software before it leaves the shop.

多個音箱單元緊密排列成一列，使其表現如同一個長形音源，投射更遠、前後覆蓋更均勻。覆蓋範圍由單元之間的夾角決定，在出庫前就以原廠預測軟體算好。

Easy to get wrong
A line array is not automatically louder. It trades vertical directivity for even coverage, and hung with the wrong splay it is just an expensive point source with comb filtering.
