Short answer: the JBL CBT 50LA-1. Both are rated 3.1/5 for sound quality (#17 and #18 of 23 column and line array PA speakers), and the JBL CBT 50LA-1 costs $585 against $1,055 for the JBL CBT 100LA-1, and with sound quality even, the cheaper one is the better buy.
What the JBL CBT 100LA-1 does well: A Constant Beamwidth Technology column from the same JBL CBT range as the measured JBL CBT 70J-1 and JBL CBT 1000, with sixteen 2” full-range drivers in a 1000mm tall cabinet. Watch for: No independent measurements yet, so it can’t be compared with ranked PA speakers.
Why pick the JBL CBT 50LA-1: A Constant Beamwidth Technology column from the same JBL CBT range as the measured JBL CBT 70J-1 and JBL CBT 1000, with eight 2” full-range drivers in a 528mm tall cabinet. The catch: No independent measurements yet, so it can’t be compared with ranked PA speakers.
Buy the JBL CBT 50LA-1. Both are rated the same for sound quality, and it costs $470 less than the JBL CBT 100LA-1.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: JBL CBT 100LA-1 2.7 to 3.5; JBL CBT 50LA-1 2.7 to 3.5). Treat this verdict as provisional.

The Two Speakers In Full
JBL CBT 100LA-1: $1,055.00 each Passive Estimated Amazon eBay
Same family: the JBL CBT 50LA-1 (smaller model, ranked higher, estimated 3.1/5), the JBL CBT 70J-1 (smaller model, ranked higher, rated 3.4/5), the JBL CBT 200LA-1 (larger model, ranked higher, estimated 3.2/5) and the JBL CBT 1000 (larger model, ranked higher, rated 4.1/5).
Pros: A Constant Beamwidth Technology column from the same JBL CBT range as the measured JBL CBT 70J-1 and JBL CBT 1000, with sixteen 2” full-range drivers in a 1000mm tall cabinet. It keeps a steady 150° horizontal and switchable 15° or 40° vertical pattern across frequency, which helps speech intelligibility in reverberant rooms, and JBL rates it at 121dB (narrow mode).
Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. Its 2” drivers have no separate woofer or tweeter and roll off below 80Hz, so music needs a subwoofer, and it requires an external amplifier.
