Polk 11T (c. 1988–1993)
Little is documented about the Polk 11T outside its late-1980s advertising, and that advertising calls the model the RTA 11t. It was Polk's top conventional (non-SDA) tower speaker at the time. The campaign ran from at least late 1988 into 1989. It called the 11t the finest conventional speaker Polk made outside its SDA line, and pitched it as big-speaker performance in a small floor footprint. Audio (February 1989, p.21) carried the ad, which listed the 11t at $449.95 each and claimed 250-watt power handling and 90 dB efficiency.
The tall, slender cabinet was central to the design. Polk said the deep, narrow shape allowed substantial internal volume for high efficiency and powerful bass while taking up less than a square foot of floor space. Those figures come from the manufacturer's own ads, not an independent review. The usual supporting details - driver complement, crossover points, cabinet volume, weight - are not documented in the surviving record. A dealer ad from spring 1993 shows the 11T was still in the lineup, offered at its lowest price yet, with a free CS100 center-channel speaker bundled when you bought a qualifying pair of Polk fronts and a set of Polk rears (HiFI-Stereo, April 1993, p.35). Surviving ads identify the speaker as the RTA 11t, the name under which it also appears in the Archive's separate RTA-11T entry.
