EXPERIENCE
TRUE STEREO
In 1985, Polk Audio stunned the audio world with
the flagship SDA-SRS speaker, which featured
Polk-patented Stereo Dimensional Array (SDA)
surround technology. Having already excelled in
the making of the Legend series, Polk engineers
went a step further to dramatically improve
SDA-PRO™ True Stereo.
Newly patented design employs a special “Head
Shadow” filter in the dimensional array, which is built
to more exactly match — and therefore cancel out —
interaural crosstalk (IAC). An additional patent was
granted for the L800’s uniquely designed 15-degree
angled baes. This design angles the transducers
more precisely toward the listener, which removes
any loss of high frequency extension and the need
to “toe-in” the loudspeakers.
Available only on the new Legend L800. SDA-PRO
delivers the most lifelike, detailed imaging you have
ever heard — it is the only True Stereo™ loudspeaker.
