Short answer: the JBL CBT 1000 + CBT 1000E. It ranks #2 of 13 line array and installation pa speakers by sound quality (rated 4.3/5); the L-Acoustics SYVA ranks #5 (rated 4.0/5).
Why pick the JBL CBT 1000 + CBT 1000E: Adding the CBT 1000E extension below the CBT 1000 gives a 5.70 standalone preference score, one of the highest of any PA speaker we list, and 7.96 with an ideal subwoofer. The tradeoff: The measurements are manufacturer supplied and spinorama rates their quality as low.
Why pick the L-Acoustics SYVA: Vendor Spinorama data gives preference scores of 4.01 standalone and 7.58 with an ideal subwoofer. Watch for: On its own it reaches only about 106Hz (-3dB), so it cannot be used without a subwoofer.

JBL CBT 1000 + CBT 1000E: $4,945.00 Passive B&H Photo Video eBay
Pros: Adding the CBT 1000E extension below the CBT 1000 gives a 5.70 standalone preference score, one of the highest of any PA speaker we list, and 7.96 with an ideal subwoofer. Bass reaches 51.5Hz at -3dB and about 40Hz at -10dB, so the pair can run full range without a subwoofer, and a 1.4dB reference band keeps the tonal balance very even. JBL’s Constant Beamwidth Technology gives switchable vertical coverage for long rooms. Measured bass extension of 51.5Hz (-3dB).
Cons: The measurements are manufacturer supplied and spinorama rates their quality as low. At $4945 the combination is expensive, stands about 2m tall and weighs around 50kg, and it needs an external amplifier.

L-Acoustics SYVA Passive 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.
