    "description": "Package Includes\nJL Audio C1-690tx 6\" x 9\" 3 Way Coaxial Car Speaker System\nStinger RKXSK Expert Sound Proofing Deadening Material 2 Sheet Speaker Kit\nC1-690tx\nCoaxial 3-Way Speaker System: 6 x 9-inch (150 x 230 mm) Woofer, 1.0-inch (25 mm) Aluminum Dome Tweeter, 0.75-inch (19 mm) Aluminum Dome Super Tweeter\nC1 speakers deliver real substance and great audio performance in a format designed for easy fit behind factory grilles.\nTo facilitate fit, spacer adaptor rings are included allowing the C1-690tx to be installed in bottom-mount applications.\nC1 woofer drivers benefit from proprietary FEA modeling and JL Audio's expertise in low-frequency driver design.\nThis knowledge is used to create speakers that can play loudly, while maintaining a smooth, dynamic, low distortion sound. At the core of the C1-690tx is a proprietary, stamped, steel 6 x 9-inch (150 x 230 mm) oval frame and a DMA-optimized motor system.\nA mineral-filled, injection-molded polypropylene cone is suspended with a rubber surround on the front, and a carefully engineered flat Conex® spider at the top of the voice coil, to precisely control motion and prevent impact between the voice coil and the back plate. Tinsel leads are carefully routed and attached to the spider to prevent fatigue and buzzing. These are the same kinds of features and materials normally found on much more expensive loudspeakers.\nEquipped with dual true, edge-driven, aluminum dome tweeters, the C1-690tx stands apart from others in its category with superior high-frequency clarity and separation. The design of each tweeter delivers inherently excellent off-axis response and high-frequency extension. Both high-frequency drivers also benefit from the damping of silk surround suspensions and Ferrofluid in the voice coil gaps, along with the superior strength of neodymium magnetics. A true, mixed order filter network is employed to further enhance smoothness and improve power handling.\nWhen it comes to value, C1 is the real deal!\nGeneral Specifications\nContinuous Power Handling (RMS) 60 W\nRecommended Amplifier Power (RMS) 10 - 100 W / Ch.\nSystem Efficiency 90.5 dB @ 1 W / 1 m\nSystem Nominal Impedance 4 Ω\nSystem Frequency Response 36 Hz - 24 KHz ± 3 dB\nCoaxial Physical Specifications\nFrame Outer Diameter* (A) 6.38 x 9.33 in / 162 x 237 mm\nGrille Tray Outer Diameter (B) N/A\nMotor Outer Diameter (C) 3.94 in / 100 mm\nFrontal Coaxial Tweeter Protrusion** (D) 0.72 in / 18 mm\nFrontal Grille Protrusion (E) N/A\nMounting Hole Diameter (F) N/A\nMounting Depth (G) 3.09 in / 79 mm\n*Does not take into account mounting tabs\n**Frontal coaxial tweeter protrusion measured from mounting surface\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",
