This page ranks 3 line source and installation PA systems: slim column-style line arrays that throw sound evenly across a room, built for venues, houses of worship, conference rooms, and fixed installs rather than portable two-way boxes. Prices are per speaker unless stated otherwise.
Line sources trade a very wide horizontal pattern for a narrow vertical one, which keeps sound off ceilings and floors and evens out level from the front row to the back. Most of these systems are passive and rely on matched amplified controllers, and many need a companion low-frequency cabinet for full-range sound. Ranking weighs measured sound quality alongside coverage, output, bass extension, and weight.
Manufacturer maximum-SPL claims are measured under different conditions from one brand to the next, so treat them as a rough guide rather than a precise comparison.

#1 L-Acoustics SYVA-low+top eBay
Pros: Vendor Spinorama data gives preference scores of 6.05 standalone and 8.11 with an ideal subwoofer, the best in this ranking. Pairing the SYVA line source with SYVA Low adds two 12-inch drivers, extending bass to about 50Hz (-3dB) and 137dB peak SPL. Listening-window narrow-band deviation is 0.188, and the 140° horizontal pattern covers wide rooms from one slim column. Measured bass extension of 50Hz (-3dB).
Cons: A passive system that needs L-Acoustics amplified controllers (LA4X, LA12X or LA8). The two-element stack is 2.15m tall and about 50kg, so it is an installed or touring system rather than a grab-and-go box. Vertical coverage is only about 25°, which suits seated audiences but limits use on steep or multi-tier rooms.

#2 L-Acoustics SYVA eBay
Pros: Vendor Spinorama data gives preference scores of 4.01 standalone and 7.58 with an ideal subwoofer. Six 5-inch drivers and three compression drivers form a slim 21kg line source with 140° horizontal coverage and 137dB peak SPL. It is intended to be paired with SYVA Low or a subwoofer, which is where the system’s bass comes from. Measured bass extension of 106Hz (-3dB).
Cons: On its own it reaches only about 106Hz (-3dB), so it cannot be used without a subwoofer. It is a passive line source that needs L-Acoustics amplified controllers, and the narrow 25° vertical coverage limits placement flexibility. Listening-window narrow-band deviation is 0.319 and on-axis deviation is higher than the coaxial competition.

#3 L-Acoustics SOKA eBay
Pros: An ultra-shallow line source only about 10cm deep and 9.4kg that reaches 133dB with 140° horizontal coverage, which lets it hide against a wall or column. Vendor Spinorama data gives preference scores of 3.21 standalone and 6.99 with an ideal subwoofer. Measured bass extension of 128Hz (-3dB).
Cons: Bass reaches only about 128Hz (-3dB), so it needs a subwoofer or a bass companion, and it is passive, so it requires L-Acoustics amplified controllers. Listening-window narrow-band deviation is 0.348 and pricing is dealer quoted.
