#17 JBL CBT 50LA-1: $585.00 each Passive Estimated Amazon eBay
Same family: the JBL CBT 70J-1 (larger model, ranked higher, rated 3.4/5), the JBL CBT 100LA-1 (larger model, ranked lower, estimated 3.1/5), 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 eight 2” full-range drivers in a 528mm tall cabinet. It keeps a steady 150° horizontal and 20° vertical pattern across frequency, which helps speech intelligibility in reverberant rooms, and JBL rates it at 115dB continuous.
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.
