Short answer: the JBL CBT 70J-1. It ranks #10 of 23 column and line array PA speakers by sound quality, rated 3.4/5, at $1,480. The JBL CBT 100LA-1 ranks #18, rated 3.1/5, at $1,055, $425 cheaper, which does not close the gap in sound quality.
Why pick the JBL CBT 70J-1: Independently measured by Audio Science Review, with a 5.87 preference score with an ideal subwoofer and a 3.20 directivity-index deviation. The catch: Bass measures 120Hz at -3dB and about 62Hz at -10dB, and the standalone score is only 2.95, so it needs a subwoofer for music.
The case for the JBL CBT 100LA-1: 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.
Buy the JBL CBT 70J-1. It is rated higher for sound quality, and saving $425 with the JBL CBT 100LA-1 does not make up for the sound-quality gap.
Worth knowing: the JBL CBT 100LA-1 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.7 to 3.5, so treat this verdict as provisional.

JBL CBT 70J-1: $1,480.00 Passive Amazon B&H Photo Video eBay
Same family: the JBL CBT 50LA-1 (smaller model, ranked lower, estimated 3.1/5), the JBL CBT 100LA-1 (larger model, ranked lower, estimated 3.1/5), the JBL CBT 200LA-1 (larger model, ranked lower, estimated 3.2/5) and the JBL CBT 1000 (larger model, ranked higher, rated 4.1/5).
Pros: Independently measured by Audio Science Review, with a 5.87 preference score with an ideal subwoofer and a 3.20 directivity-index deviation. Sixteen 1-inch tweeters and four 5-inch woofers give switchable 25° or 45° vertical coverage for long-throw or medium rooms, with a 131dB peak and a speech or music voicing switch. A pan and tilt wall bracket is included. Measured bass extension of 120.1Hz (-3dB).
Cons: Bass measures 120Hz at -3dB and about 62Hz at -10dB, and the standalone score is only 2.95, so it needs a subwoofer for music. A 4.0dB reference band and 0.573 listening-window deviation mean tonal balance is uneven. It is passive and needs an external amplifier.

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.
