Short answer: the L-Acoustics SYVA for better sound quality, the Alcons Audio QRP20 for the lower price. The L-Acoustics SYVA ranks #5 of 33 column and line array PA speakers, rated 4.0/5, at $13,100. The Alcons Audio QRP20 ranks #9, rated 3.6/5, at $4,200, $8,900 cheaper.
The L-Acoustics SYVA is the more accurate option. A slim passive column with accurate sound, very wide coverage, and high output, designed to pair with a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 4.01 against 3.38 for the Alcons Audio QRP20. The tradeoff: On its own it reaches only about 106Hz (-3dB), so it cannot be used without a subwoofer.
The Alcons Audio QRP20 is the deeper-bass pick. A slim ribbon column with high output and a choice of wide horizontal coverage, built for discreet installs. Its bass reaches about 90Hz before falling 3dB, against 106Hz for the L-Acoustics SYVA. The catch: Bass reaches only 90Hz at -3dB and about 81Hz at -10dB, so it needs a subwoofer for music.
Buy the L-Acoustics SYVA when sound quality outweighs the price for you, and the Alcons Audio QRP20 when the price outweighs sound quality instead.
