JBL AC18/26: $1,070.67 each Passive Estimated Amazon eBay

Same family: the JBL AC15 (smaller model, ranked lower, estimated 2.6/5), the JBL AC16 (smaller model, ranked lower, estimated 2.8/5), the JBL AC25 (smaller model, ranked lower, rated 2.6/5), the JBL AC26 (smaller model, ranked lower, estimated 2.9/5) and the JBL AC28/26 (larger model, ranked higher, estimated 3.1/5).

Pros: A compact JBL Professional installation speaker from the same AC range as the measured JBL AC25: an 8” woofer with a rotatable 120° x 60° horn. JBL rates it at 92dB sensitivity and 116dB maximum SPL with 120° x 60° coverage and bass to 52Hz (-10dB), in an enclosure weighing 12.8 kg with mounting points for walls and ceilings.

Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. It is a passive installation speaker that needs an amplifier and, for best results, JBL’s recommended EQ, and the only measured AC model scored poorly, so treat the estimate with caution.
