PT™ Progressive Transition™ Waveguides - JBL's new Progressive Transition Waveguides represent the latest in horn technology. In addition to providing smooth, low distortion sound, PT waveguides deliver uniform off-axis frequency response to every point within the intended coverage area -- not just in the horizontal and vertical planes -- resulting in superior arrayability of multiple loudspeaker systems. PT Waveguides combine outstanding pattern control with undistorted sound for natural music and intelligible speech.

Incorporated into all the cone midrange models. CMCD technology is more than a simple displacement plug. In addition to providing increased output and lower distortion, this cone-based true compression driver design extends bandwidth (both up and down in frequency) to cover the entire vocal range seamlessly, allows for better waveguide pattern control by reducing the projection aperture, and improves phase coherency of the midrange signal for clearer, more intelligible audio quality.

Many of the AE models come in multiple power ranges or are very similar to comparable-coverage models at a higher or lower power point, allowing selection of just the right speaker for the required output capability. Mid-high frequency versions of some models can be used for use in voice-only PA, or as delay-fills that match the character of the full-range main speakers.

Sometimes you need maximum pattern control and other times the speaker needs to be as compact as possible. "AM" models are performance-maximized for the greatest pattern control to the lowest frequency possible. "AC' models are compact speakers that fit in areas where a smaller frontal profile is required.
