RTA 12C Line Source Loudspeaker System:

Polk Audio's never satisfied engineers wanted to eliminate the problems associated with unwanted reflections caused by placing the high frequency tweeter on the front surface of a cabinet. The sound patterns, produced by the tweeter, radiate along the surface of the cabinet and the resultant reflections cause imaging distortions. They rob the listener of the ability to accurately hear all of the potential benefits of stereophonic reproduction. With the aid of Polk Audio's newly developed digital sampling fast Fourier transform computer testing procedure they were able to place the tweeter on the top of the speaker's cabinet, completely eliminating the problems associated with troublesome diffractions.

•Open air mounted, phase aligned high frequency radiator.

•Tri-laminate polymer drivers.

•SL2000 moving coil dome radiator.

•SW120 fluid coupled planar subwoofer.

•Complex dual isophase crossover network.

•Anti-diffraction "ramp" is used to eliminate any spurious high frequency reflections from the top of the cabinet.

The sonic result is a cleaner, clearer, more lifelike sound with greater power handling and dynamic range capability than ever before.
