Bringing It To Maximum

The AC15 is an ultra-compact fullrange loudspeaker system designed to provide maximum bandwidth and SPL in a single system package and yet be visually unobtrusive. The enclosure design allows for installation very close to walls and ceilings making it an ideal choice for under balcony, column, or wall mounting. The high frequency device is a 1" dome tweeter integrated into a newly designed 90° x 90° waveguide providing even coverage throughout the intended usage area. The combination exhibits smooth power response resulting in extremely natural voicing. The AC15 utilizes a 5.25" Symmetrical Field Geometry (SFG™) LF Transducer with a copperclad aluminum edge wound 1.5" voice coil and a copper-capped pole piece that improves performance by reducing voice coil inductance and distortion.

The rugged multi-ply hardwood enclosure is designed to work in the vertical plane as well as in the horizontal plane. Mounting points are provided for an optional U-bracket and for an OmniMount® type bracket.

The rugged plywood enclosure features JBL’s textured DuraFlex™ finish and is equipped with a heavy duty powder coated steel, foam-backed grille.

Loudspeaker Specifications

Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
80 - 20,000 Hz
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
