JBL AC18/26 vs JBL AC15

Short answer: the JBL AC18/26. It ranks #10 of 26 surface-mount and background music speakers by sound quality, rated 3.0/5, at $1,070.67; the JBL AC15 ranks #17, rated 2.6/5, and costs $1,180, so there is not much of a tradeoff to weigh.

The JBL AC18/26 is the better-sounding option. 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. The catch: No independent measurements yet, so it can’t be compared with ranked PA speakers.

What the JBL AC15 does well: A compact JBL Professional installation speaker from the same AC range as the measured JBL AC25: the smallest model, with a dome tweeter like the AC25. The catch: No independent measurements yet, so it can’t be compared with ranked PA speakers.

Buy the JBL AC18/26. It is rated higher for sound quality than the JBL AC15 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: JBL AC18/26 2.6 to 3.4; JBL AC15 2.2 to 3.0). Treat this verdict as provisional.

The Two Speakers In Full

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.
