1Frequency response and range measured on-axis with recommended active EQ in an anechoic environment.

2Power handling tested using pink noise filtered to meet IEC 268-5, 6 dB crest factor, 100 hours, with recommended EQ.

3Sensitivity measured in free field (no boundary-loading gain) with recommended active EQ, referenced to 1W/1m.

4Maximum SPL calculated from sensitivity and power handling specifications, exclusive of power compression.


The 12A is a two-way, high efficiency, passive loudspeaker. It is designed as a compact high performance system for the reproduction of speech and music program material.

The 12A has a one-inch exit compression driver coupled to a 75 X 75 degree wooden waveguide horn reproducing high frequencies, and a twelve-inch cone transducer in a tuned enclosure for the low frequencies. A high quality passive network operates very efficiently, also providing EQ points for a flat frequency response. The sturdy multi-ply plywood enclosure, with a catalyzed polyurethane finish, is designed to withstand the most demanding portable applications. A perforated, powder coated steel grill with a high transmission ratio offers excellent protective properties.

The 12A can be purchased in two versions. The portable configuration has large recessed handles and a stand mount, while the installation version has a standard twelve point flyware system. Both are available in white, black or unfinished exterior. The 12A excels in a myriad of diverse applications requiring a compact trapezoid enclosure, and offers extraordinary performance and value.

 “Everyone has been very impressed with the sound quality of the WorxAudio equipment. Senior Pastor Jon Wagner recently took a close listen to the loudspeakers and has asked for his main sanctuary to have WorxAudio installed. When one project leads to another, it doesn’t get any better than that!”
