It is difficult to design high quality speakers to fit inside the confines of a flat panel television because speaker drive units need space, width and depth to sound their best. Sony carefully measured the performance of the speakers, making meticulous note of any frequency and phase issues. Then we corrected the issues with the digital signal processing of the Clear Phase Speaker. In technical terms, the result is remarkably even volume across the frequency band and superbly even delay across the frequency band. You will hear a clarity of tone and a precision in spatial location that is remarkable in television sound.
