Pair of great sounding Polk Audio book shelf speakers. Great as stand alone speakers or incorporating into a home audio system. I also have a Subwoofer and center channel speakers to match. See my other listings. Trades and offers welcome. I am happy to ship but please be aware that shipping will cost more than the $13 shipping cost OfferUp quotes. This ear-pleasing pair carries on Polk's legacy of impressive bookshelf speakers, using designs inherited from their renowned RT tower series. The RT35i provides amazing bass output for its size thanks to a 6-1/2" Dynamic Balance® driver mounted on a raised bezel (no more unwanted grille diffractions!). Power Port technology ensures that the bass is clean and powerful, while a 1" trilaminate tweeter adds smooth, accurate highs. The RT35i also features an ingenious wall-mount system — the Power Port assembly serves as a bracket! Finished in real black oak wood veneer. Recommended center channel speaker: Polk CS245i or CSi30. Recommended surround speakers: Polk RT25i.
