"description": "Package Includes\nJL Audio C1-690X 6\" x 9\" 2-Way Coaxial Car Speaker System\nStinger RKXSK Expert Sound Proofing Deadening Material 2 Sheet Speaker Kit\nC1-690X\nStarter Speakers Like no Other\nAfter an extensive tour of JL Audio HQ, I got the opportunity to talk to their engineering and development team about the current JL Audio lineup and upcoming projects. Given all the work they're doing with premium car audio, I was surprised by how excited they were for customers to hear their workhorse C1 Series — speakers designed for drivers simply looking for a sensible factory speaker replacement, not necessarily an audiophile-grade solution. The reason for that excitement, once I heard it, made perfect sense — every JL Audio speaker must uphold the quality and sound associated with the name. You may be looking for something that's just listenable, but what you'll get with the C1 Series is an audio experience that puts it at the top of its class. And then, just maybe, you'll end up being a JL Audio fan for life.\nProduct Highlights:\n6\"x9\" 2-way speakers (pair)\ninjection-molded mineral-filled polypropylene woofer cone with rubber surround\n1\" aluminum edge-driven dome tweeter\nhandles up to 60 watts RMS (225 watts peak power)\nfrequency response: 39-22,000 Hz\nsensitivity: 94 dB at 2.83 volts\ntop-mount depth: 2-3/4\"\ngrilles not included\nMFR # 010-03351-00\nWhat's in the Box:\nJL Audio C1-690x owner's manual\nIf you need assistance accessing this owner's manual, please give us a call.\nTwo 2-way speakers\n2 Bottom mount brackets\nEight 1-1/2\" Screws (#8)\nTwo 0.187\" Crimpable female quick slides\nTwo 0.110\" Crimpable female quick slides\nOwner's manual\n{ note_speaker_nogrill }\nStinger RKXSK Expert Sound Proofing Deadening Material 2 Sheet Speaker Kit\nExpert level sound dampening\nAluminum outer layer\nSelf adhesive\nEasy installation\nUse on all metal panels, doors, roof, floor, firewall & trunk\nKills panel resonance, squeaks and rattles\nHighest damping vs. weight ratio of any material available\nImproves overall audio frequency response and bass output\nSpeaker kit\nExpert RoadKill Published Specifications\nMinimum Thickness 0.080in\nMinimum Weight 0.65bs/ft2\nAluminum Layer- 6 mils",
