SDA HEAD SHADOW AND
ANGLED BAFFLES
Legend L800 SDA Pro speakers feature new developments in
Polk-patented SDA technology.
Head Shadow – When the IAC passes across the listeners face,
it is modified in the same manner as light trying to go around
an obstacle. This is known as the “head shadow.” Polk L800
speakers feature sophisticated dimensional HS (head shadow)
crossover to more precisely match and cancel out IAC noise,
creating precise, immersive and expansive imaging.
Angled Baffles – Angled baffles in the L800 allow the main
stereo speaker arrays to point directly at the primary listening
area, providing the best natural dispersion of the stereo signal.
