This is a brand new pair of PowerBass L-4102X 4x10" 210 watt car audio speakers. These speakers fit most 4x10" openings found in many vehicles. PowerBass uses superior materials to build speakers that not only handle lots of power, but sound great doing it. These speakers make a good choice for anyone who wants to improve sound quality without spending a lot of cash. They feature a 2-way design that does a great job of covering your music's full frequency range. The black Z-2 zirconium cone is supported by a tough butyl rubber surround, and a stamped stainless steel basket; so it will deliver strong performance over the long haul. The Aluminum dome 3/4" tweeter reproduces high frequencies well above normal hearing, sharpening the details that define your instrumental and vocal soundstage. Speaker wire and mounting hardware are also included, so installation should be a breeze!
