Short answer: a tie on sound quality. Both are rated 4.1/5 (#3 and #4 of 13 line array and installation pa speakers), so choose on features and fit.
Why pick the JBL CBT 1000: Its 8.13 preference score with an ideal subwoofer is one of the highest of any PA speaker we list, and a 0.168 listening-window deviation shows a very even tonal balance for listeners across the coverage area. The catch: The measurements are manufacturer supplied and spinorama rates their quality as low.
What the Kling Freitag PIA M does well: High-quality manufacturer measurements give preference scores of 4.50 standalone and 7.92 with an ideal subwoofer, with a 1.7dB reference band and 0.82 predicted in-room smoothness. Watch for: Bass is limited, at 95Hz for -3dB and about 82Hz for -10dB in bass-reflex mode, so it needs a subwoofer for music.
Buy the JBL CBT 1000 or the Kling Freitag PIA M on features: they are rated the same for sound quality at close to the same price.

JBL CBT 1000: $3,075.00 Passive B&H Photo Video eBay
Pros: Its 8.13 preference score with an ideal subwoofer is one of the highest of any PA speaker we list, and a 0.168 listening-window deviation shows a very even tonal balance for listeners across the coverage area. Six 6.5-inch woofers and 24 one-inch tweeters in JBL’s Constant Beamwidth design give switchable vertical coverage, 102dB sensitivity and a 1,500W rating. The optional CBT 1000E extension adds bass and throw. Measured bass extension of 115Hz (-3dB).
Cons: The measurements are manufacturer supplied and spinorama rates their quality as low. On its own the standalone score is 4.67, and the measured bass response is uneven, reaching 115Hz at -3dB but about 48Hz at -10dB, so a subwoofer or the CBT 1000E helps. It is passive, weighs 24.5kg and needs an external amplifier.

Kling Freitag PIA M Passive eBay
Pros: High-quality manufacturer measurements give preference scores of 4.50 standalone and 7.92 with an ideal subwoofer, with a 1.7dB reference band and 0.82 predicted in-room smoothness. The 3-way column has an adjustable tweeter array (5°, 15° or 25° vertical), a cardioid midrange and a woofer section switchable between bass reflex and cardioid to cut sound behind the speaker. It reaches 132dB from a slim 12.2kg cabinet. Measured bass extension of 95Hz (-3dB).
Cons: Bass is limited, at 95Hz for -3dB and about 82Hz for -10dB in bass-reflex mode, so it needs a subwoofer for music. It is passive and meant for Kling & Freitag amplifiers, and it is sold only through pro dealers with no published price.
