Short answer: the JBL AC15, though neither ranks well in its class. It ranks #17 of 26 surface-mount and background music speakers by sound quality, rated 2.6/5, at $1,180. The Bose DesignMax DM8SE ranks #23, rated 2.4/5, at $878, $302 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 26 surface-mount and background music speakers; for better sound, the JBL Control 24CT ranks #1 at $350.
Why pick the JBL AC15: 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. Watch for: No independent measurements yet, so it can’t be compared with ranked PA speakers.
The case for the Bose DesignMax DM8SE: The outdoor-rated replacement for the measured Bose DesignMax DM8S, keeping its 8” woofer and center-firing coaxial 1” compression driver with 150W handling and a 52Hz to 20kHz range. The catch: No independent measurements yet, so it can’t be compared with ranked PA speakers.
Buy the JBL AC15. It is rated higher for sound quality, and the $302 saving on the Bose DesignMax DM8SE is not enough to make up the difference.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: JBL AC15 2.2 to 3.0; Bose DesignMax DM8SE 2.1 to 2.7). Treat this verdict as provisional.

The Two Speakers In Full
JBL AC15: $1,180.00 per pair Passive Estimated Amazon eBay
Same family: the JBL AC16 (larger model, ranked higher, estimated 2.8/5), the JBL AC25 (larger model, ranked lower, rated 2.6/5), the JBL AC26 (larger model, ranked higher, estimated 2.9/5), the JBL AC18/26 (larger model, ranked higher, estimated 3/5) 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: the smallest model, with a dome tweeter like the AC25. JBL rates it at 86dB sensitivity and 108dB maximum SPL with 90° x 90° coverage and bass to 80Hz (-10dB), in an enclosure weighing 4.7 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.

Bose DesignMax DM8SE: $878.00 each Passive Estimated Amazon eBay
Older model: the Bose DesignMax DM8S (ranked higher, rated 2.4/5). See every Bose DesignMax generation.
Same family: the Bose DesignMax DM5SE (smaller model, ranked lower, rated 2.2/5) and the Bose DesignMax DM6SE (smaller model, ranked lower, rated 2.2/5).
Pros: The outdoor-rated replacement for the measured Bose DesignMax DM8S, keeping its 8” woofer and center-firing coaxial 1” compression driver with 150W handling and a 52Hz to 20kHz range. It adds IP55 weather sealing, an aluminum grille with a rust-resistant finish and a sealed cover over the input terminals.
Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. The measured DM8S it is based on had an uneven response for its price, and it needs an external amplifier.
