RTA 11t Line Source Loudspeaker System:

Polk Audio is pleased to announce the introduction of a new home loudspeaker system, the RTA 11t. The RTA 11t is a tall, elegantly slender and deep "tower style" system which utilizes to full advantage the low diffraction characteristics resulting from the minimal frontal area intrinsic to its design to achieve outstanding imaging and low coloration.

It incorporates two 6.5" trilaminate-polymer bass midrange drivers which are symmetrically arrayed above and below a 1" polymer dome tweeter. This configuration results in the acoustic center of the two drivers coinciding exactly with that of the tweeter for almost perfect coincident radiation of the midrange and high frequencies. This results in superb driver blending and further improves imaging. In addition this driver topology achieves line source radiation of the midrange which further lowers coloration by reducing floor and ceiling reflections. The two 6.5" bass-midranges drive two 8" sub-bass radiators which are precisely tuned to different frequencies in order to further extend, control and smooth the low frequency response. The RTA11t will be available in black, walnut and rosewood vinyl finishes, as well as natural walnut and oak at a surcharge in price.
