The Polk T15 is a pair of compact, 2-way bookshelf speakers featuring a 5.25 Dynamic Balance woofer and 0.75 silk dome tweeter. They offer 89 dB sensitivity, a 60Hz–24kHz frequency response, and 8-ohm impedance, handling 20–100W per channel. These vented, wall-mountable speakers are ideal for budget home theater setups. These sound great and are in very good condition, EXCEPT that one speaker has two barely noticeable whitish discolorations on its top. So I’ve discounted the pair for this reason. Please see the pics for detail. Message me if you have any questions.
