{"title":"MKIV Powered Subwoofers with SLAPS Technology","description":"\u003cp\u003eEarthquake Sound's Supernova MKIV Series combines powerful bass performance with efficient, precision-engineered design. Featuring a high-excursion active driver with a thermally pressed poly-ether foam surround, the MKIV delivers deep, controlled bass with minimal distortion. Earthquake's patented Symmetrically Loaded Audio Passive System (SLAPS) enhances low-frequency output beyond conventional sealed and ported designs, while the integrated 450-watt amplifier provides reliable power and flexible user controls. The result is impactful, accurate bass reproduction for music and home theater applications.\u003c\/p\u003e","products":[{"product_id":"supernova-mkiv-10","title":"Supernova MKIV-10","description":"\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cspan\u003eThe Earthquake Supernova MKIV-10 subwoofer is one of Earthquake’s most raw and unadulterated performance implementations of the SLAPS technology and the Supernova nameplate itself. Built with the singular obsession to take the bone-crushing power of SLAPS, XLT woofer geometry, and 450 Watts of Enhanced Class AB wattage to the realm of affordability. Throwing etiquette and moderation completely out the window, we have shamelessly shoehorned the proverbial BigBlock V8 into a subcompact, accepting full well that some people will find this much bass at this price point downright offensive. Enjoy harder-hitting music beats and thundering movie effects from a completely gimmick-free subwoofer. No blinking displays, useless remote controls, gift bags, or plastic novelty microphones!
