Nice pair of Polk LSI-15 with VR3 Fortress Mod (totally revamped crossover). VR3 Mods really specialize in mods to Polk speakers.The improvement to the stock LSI-15 is huge, with dramatic improvement to the soundstage, transparency and tightness of the bass. The Fortress mod alone cost $450. The light shading on the top right side of the main photo is a reflection from the camera's flash.Polk Audio LSi15 Fortress Level

99.99% Copper, Gold Plated Insulated Binding Post Conservatively rated 7/10. Local pickup preferred since I no longer have the boxes for them. I'm located in Jersey City, NJ (right across from lower Manhattan) and would drive up to 30 miles for delivery. Please check my feedback on audiogon (rosstoys).
