Short answer: the L-Acoustics SYVA-low+top if sound quality matters most, the JBL CBT 1000 if price matters most. The L-Acoustics SYVA-low+top ranks #1 of 33 column and line array PA speakers, rated 4.4/5, at $19,000. The JBL CBT 1000 ranks #3, rated 4.1/5, at $3,075, $15,925 cheaper.
The L-Acoustics SYVA-low+top is the more accurate, deeper-bass pick. A slim column system with extremely accurate installed PA sound, wide coverage, and bass deep enough for full range music. Its measured preference score, a predictor of how neutral it sounds, is 6.05 against 4.67 for the JBL CBT 1000. Its bass reaches about 50Hz before falling 3dB, against 115Hz for the JBL CBT 1000. Watch for: A passive system that needs L-Acoustics amplified controllers (LA4X, LA12X or LA8).
Why pick the JBL CBT 1000: A passive column speaker with accurate, even sound across a wide audience and switchable vertical coverage for long rooms. Watch for: The measurements are manufacturer supplied and spinorama rates their quality as low.
