Short answer: the Alcons Audio QR24. Both are rated 4.0/5 for sound quality (#6 and #5 of 33 column and line array PA speakers), and the Alcons Audio QR24 costs $7,200 against $13,100 for the L-Acoustics SYVA, with sound quality a draw, the lower price decides it.
Why pick the L-Acoustics SYVA: A slim passive column with accurate sound, very wide coverage, and high output, designed to pair with a subwoofer. The catch: On its own it reaches only about 106Hz (-3dB), so it cannot be used without a subwoofer.
The Alcons Audio QR24 is the deeper-bass pick. A ribbon column module with accurate, even sound and very high output that works alone or stacked as an array. Its bass reaches about 71Hz before falling 3dB, against 106Hz for the L-Acoustics SYVA. The catch: Bass drops quickly below about 70Hz, so a subwoofer is needed for full-range music.
Buy the Alcons Audio QR24. Both are rated the same for sound quality, and it costs $5,900 less than the L-Acoustics SYVA.
