Short answer: the JBL PRX915. It ranks #10 of 62 15-inch pa speakers by sound quality, rated 3.9/5, at $999; the Yamaha CZR15 ranks #22, rated 3.7/5, and costs $1,024, so there is not much of a tradeoff to weigh.
What the JBL PRX915 does well: High-quality vendor data shows a 4.77 ideal-subwoofer preference score with 51Hz measured extension, backed by JBL’s extensive service network and 12-band parametric EQ with dbx DriveRack feedback suppression carried over from the JBL PRX912. Watch for: Its measured preference trails the 12-inch JBL PRX912, and at 53.1 lbs (24.1 kg) it is meaningfully heavier to carry to a gig than the smaller model.
What the Yamaha CZR15 does well: The passive version of the measured Yamaha DZR15, with a 15” woofer and a 2” voice coil compression driver in a plywood cabinet with 90° x 60° coverage. The tradeoff: No independent measurements yet, so it can’t be compared with ranked PA speakers.
Buy the JBL PRX915. It is rated higher for sound quality than the Yamaha CZR15 and costs less, which makes it the one to get unless you need something the other one does better.
Worth knowing: the Yamaha CZR15 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.3 to 4.1, so treat this verdict as provisional.

Yamaha CZR15: $1,024.00 Passive Estimated B&H Photo Video eBay
Same family: the Yamaha DZR10 (smallest powered model, rated 3.4/5), the Yamaha DZR12 (powered model, rated 3.9/5), the Yamaha DZR15 (powered model, ranked higher, rated 4/5), the Yamaha DZR315 (largest powered model, ranked higher, rated 3.8/5), the Yamaha CZR10 (smaller passive model, estimated 3.2/5) and the Yamaha CZR12 (smaller passive model, estimated 3.6/5).
Pros: The passive version of the measured Yamaha DZR15, with a 15” woofer and a 2” voice coil compression driver in a plywood cabinet with 90° x 60° coverage. Yamaha rates it at 800W handling, 129dB maximum SPL and bass reaching 33Hz, and its PX and PC-D amplifiers carry a dedicated processing preset for it.
Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. It needs an external amplifier and speaker processing to match the powered DZR, which has its FIR-X tuning built in. It costs about as much as the powered model before the amplifier.
