Short answer: the JBL CBT 70J-1 if sound quality matters most, the JBL COL600 if price matters most. The JBL CBT 70J-1 ranks #10 of 13 line array and installation pa speakers, rated 3.4/5, at $1,480. The JBL COL600 ranks #12, rated 3.3/5, at $386, $1,094 cheaper.
What the JBL CBT 70J-1 does well: Independently measured by Audio Science Review, with a 5.87 preference score with an ideal subwoofer and a 3.20 directivity-index deviation. Watch for: 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.
What the JBL COL600 does well: Manufacturer measurements give a 6.11 preference score with an ideal subwoofer and a 2.1dB reference band from a 598mm column only 93mm deep. The tradeoff: Bass measures 106Hz at -3dB and about 78Hz at -10dB, and output tops out at 111dB, so it is for speech and background music.

JBL CBT 70J-1: $1,480.00 Passive B&H Photo Video eBay
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.

Cons: Bass measures 106Hz at -3dB and about 78Hz at -10dB, and output tops out at 111dB, so it is for speech and background music. The data is manufacturer supplied, rated low quality, and the standalone score is 2.64.
