SA-Classic Series 6.5" Subwoofer

300 Watts RMS/ 600 Watts Peak Dual 2 or 4 ohm voice coils Large aluminum Faraday ring for smooth acoustic response High-temperature voice coil wire Spring-loaded terminals Integrated vent channels for enhanced cooling Perfect for under/behind seat sub enclosures The SA-6.5SW was created to achieve extremely high performance with less than 4” of mounting depth. Sundown uses a solid-pole design, allowing the back plate to rest against the back wall of the enclosure to reduce the mounting depth requirements even more. Twenty millimeters of mechanical excursion means surprisingly deep bass out of this mighty 6.5” sub!
