Designed and built as a product of love for car audio, this subwoofer will look as good in your installation as it will sound. As lifelong enthusiasts ourselves, we knew the demands this subwoofer would need to meet. The engineering expertise of Jacob Fuller, founder of Sundown Audio, has led to a subwoofer that can take the abuse of high-powered systems that the modern-day enthusiast likes to throw at everything. Advanced cooling techniques, high-excursion linear suspension, and classically inspired aesthetics mean The Bass Blaster will give you the best-sounding bass, for a long time, as you turn the heads of anyone that takes a look.\u003c\/p\u003e\n\u003ch2\u003eDesign\u003c\/h2\u003e\n\u003cp\u003eOur philosophy with The Bass Blaster was to recreate the feel of car audio from our youth. The blue surround is not just our branding color, it is an homage to woofers of the 1990s that used brightly colored surrounds as a signature look. The balance of the blue to the grey\/silver basket and cone harkens back to the early 2000s when some of our favorite woofer models sported a distinct style. The aluminum dust cap gives depth and texture to the woofer as a whole and adds rigid reinforcement to the cone body. The genesis of the design was the motor itself, the large vent for the four-inch coil caught our eye in car audio shops in the 1990s. Jacob Fuller captured that look while tapering the vent and adding a pole cap so as to not compromise modern cooling techniques for the best performance-to-aesthetics ratio possible. Topped off with the metal mesh over the magnet slugs, The Bass Blaster is the 90s\/2000s woofer we all wish we had in our teens, but even better that we have it in our 40s.\u003c\/p\u003e\n\u003ch2\u003eGeneral Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; height: 176.344px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height:

Designed and built as a product of love for car audio, this subwoofer will look as good in your installation as it will sound. As lifelong enthusiasts ourselves, we knew the demands this subwoofer would need to meet. The engineering expertise of Jacob Fuller, founder of Sundown Audio, has led to a subwoofer that can take the abuse of high-powered systems that the modern-day enthusiast likes to throw at everything. Advanced cooling techniques, high-excursion linear suspension, and classically inspired aesthetics mean The Bass Blaster will give you the best-sounding bass, for a long time, as you turn the heads of anyone that takes a look.\u003c\/p\u003e\n\u003ch2\u003eDesign\u003c\/h2\u003e\n\u003cp\u003eOur philosophy with The Bass Blaster was to recreate the feel of car audio from our youth. The blue surround is not just our branding color, it is an homage to woofers of the 1990s that used brightly colored surrounds as a signature look. The balance of the blue to the grey\/silver basket and cone harkens back to the early 2000s when some of our favorite woofer models sported a distinct style. The aluminum dust cap gives depth and texture to the woofer as a whole and adds rigid reinforcement to the cone body. The genesis of the design was the motor itself, the large vent for the four-inch coil caught our eye in car audio shops in the 1990s. Jacob Fuller captured that look while tapering the vent and adding a pole cap so as to not compromise modern cooling techniques for the best performance-to-aesthetics ratio possible. Topped off with the metal mesh over the magnet slugs, The Bass Blaster is the 90s\/2000s woofer we all wish we had in our teens, but even better that we have it in our 40s.\u003c\/p\u003e\n\u003ch2\u003eGeneral Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; height: 176.344px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height:
