Short answer: the L-Acoustics SYVA-low+top. It ranks #1 of 13 line array and installation pa speakers by sound quality (rated 4.4/5); the JBL CBT 1000 ranks #3 (rated 4.1/5).
What the L-Acoustics SYVA-low+top does well: Vendor Spinorama data gives preference scores of 6.05 standalone and 8.11 with an ideal subwoofer, the best in this ranking. Watch for: A passive system that needs L-Acoustics amplified controllers (LA4X, LA12X or LA8).
Why pick the JBL CBT 1000: Its 8.13 preference score with an ideal subwoofer is one of the highest of any PA speaker we list, and a 0.168 listening-window deviation shows a very even tonal balance for listeners across the coverage area. Watch for: The measurements are manufacturer supplied and spinorama rates their quality as low.

L-Acoustics SYVA-low+top Passive 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.

JBL CBT 1000: $3,075.00 Passive B&H Photo Video eBay
Pros: Its 8.13 preference score with an ideal subwoofer is one of the highest of any PA speaker we list, and a 0.168 listening-window deviation shows a very even tonal balance for listeners across the coverage area. Six 6.5-inch woofers and 24 one-inch tweeters in JBL’s Constant Beamwidth design give switchable vertical coverage, 102dB sensitivity and a 1,500W rating. The optional CBT 1000E extension adds bass and throw. Measured bass extension of 115Hz (-3dB).
Cons: The measurements are manufacturer supplied and spinorama rates their quality as low. On its own the standalone score is 4.67, and the measured bass response is uneven, reaching 115Hz at -3dB but about 48Hz at -10dB, so a subwoofer or the CBT 1000E helps. It is passive, weighs 24.5kg and needs an external amplifier.
