By combining woven Kevlar fibers with a specific paper damping compound, this 6-inch driver provides the lightning-fast transient response and structural stiffness of Kevlar while retaining a remarkably smooth, well-behaved top-end roll-off. The mirror-black phase plug improves high-frequency dispersion and mid-band transparency. This design keeps the critical midrange clear, detailed, and phase-coherent, allowing for simpler, lower-order crossover configurations. The muted bluish color of the Kevlar material with the black phase plug give a really nice overall appearance.\u003c\/p\u003e\n\u003cp\u003eThe woofer is built on a cast aluminum basket that provides maximum frame rigidity while keeping rear-wave reflections to a minimum. It has a fully shielded ferrite magnet system, making it safe for placement near sensitive electronics and home theater systems without magnetic interference. With an Fs of 50 Hz and a 4.3mm linear Xmax, the L6-4R delivers clean, impactful bass response down to 49 Hz in a modest 12-liter (0.42 cu ft) vented enclosure.\u003c\/p\u003e\n\u003cp\u003eTo save you a trip to the hardware store, we include a custom-matched Installation Kit at no extra charge so you can start building immediately. Each L6-4R woofer you buy comes with a pre-cut gasket, two gold plated quick connect terminals, and mounting screws for free.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(40, 140, 204);\"\u003eHighlights\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKevlar-Paper Composite Cone and Phase Plug:\u003c\/strong\u003e Delivers high rigidity and low mass for fast transients, with a phase plug that optimizes off-axis dispersion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForgiving Crossover Behavior:\u003c\/strong\u003e Smooth, natural frequency roll-off from 2kHz to 3kHz with negligible cone breakup simplifies network design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Quality:\u003c\/strong\u003e Built with a cast aluminum frame and a high-temperature Kapton voice coil former for consistent thermal handling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Installation Kit Included:\u003c\/strong\u003e Ships with the exact matching mounting screws and quick-connect wire terminals needed to start your build immediately.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cstyle\u003e\ntable {\n  font-family: Arial, sans-serif;\n  border-collapse: collapse;\n  width: 100%;\n}\n\ntd, th {\n  border: 1px solid #dddddd;\n  text-align: left;\n  padding: 8px;\n}\n\ntr:nth-child(even) {\n  background-color: #f5f5f5;\n}\n\u003c\/style\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(40, 140, 204);\"\u003eHiVi L6-4R Specifications\u003c\/span\u003e\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"width: 40%;\"\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHiVi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eL6-4R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Diameter\u003c\/td\u003e\n\u003ctd\u003e6 Inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCone Material\u003c\/td\u003e\n\u003ctd\u003eWoven Kevlar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance\u003c\/td\u003e\n\u003ctd\u003e4 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Handling (RMS)\u003c\/td\u003e\n\u003ctd\u003e35 watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Handling (MAX)\u003c\/td\u003e\n\u003ctd\u003e70 watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e88dB (2.83v\/1m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e49 - 3500 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutside Diameter\u003c\/td\u003e\n\u003ctd\u003e170mm (6.7 inches)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCutout Diameter\u003c\/td\u003e\n\u003ctd\u003e147mm (5.8 inches)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Depth\u003c\/td\u003e\n\u003ctd\u003e96mm (3.78 inches)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e4.0 pounds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cstyle\u003e\ntable {\n  font-family: Arial, sans-serif;\n  border-collapse: collapse;\n  width: 100%;\n}\n\ntd, th {\n  border: 1px solid #dddddd;\n  text-align: left;\n  padding: 8px;\n}\n\ntr:nth-child(even) {\n  background-color: #f5f5f5;\n}\n\u003c\/style\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(40, 140, 204);\"\u003eThiele-Small Parameters\u003c\/span\u003e\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"width: 40%;\"\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResonant Frequency (Fs)\u003c\/td\u003e\n\u003ctd\u003e50 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC Resistance (Re)\u003c\/td\u003e\n\u003ctd\u003e3.6 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompliance Eq.
