Just clean, deep bass that fills your cabin naturally.\u003c\/p\u003e\n\u003ch3\u003eWhat Is Free-Air?\u003c\/h3\u003e\n\u003cp\u003eA free-air (infinite baffle) subwoofer is designed to play without a traditional sealed or ported box. Instead, it uses the trunk or cargo area of your vehicle as its rear air volume. The result is smooth, natural-sounding bass with less weight, less bulk, and more usable space in your vehicle. If you want serious low end without sacrificing your entire trunk, free-air is the way to go.\u003c\/p\u003e\n\u003ch3\u003eSpecifically Tuned for Open-Air Performance\u003c\/h3\u003e\n\u003cp\u003eThis isn't just a standard MX without a box recommendation — it's a purpose-built free-air subwoofer. The suspension and motor parameters have been specifically tuned for higher Qts values, which means the driver controls its own cone movement without relying on the air pressure inside a sealed enclosure. The result is smooth, controlled bass response in free-air and vented applications where a standard sub would sound loose and undefined.\u003c\/p\u003e\n\u003ch3\u003eUnitized Aluminum Cone Technology\u003c\/h3\u003e\n\u003cp\u003eThis isn't just an aluminum cone bolted to a voice coil — it's a unitized structure where the cone and voice coil are fused into a single integrated assembly. The coil is bonded to a thermally-conductive former that's actually part of the aluminum cone itself, creating a direct heat path from the voice coil straight into the heat-sinking alloy cone. Heat doesn't get trapped — it gets pulled out. The result is dramatically higher power capacity, lower distortion, and longer life than conventional designs.\u003c\/p\u003e\n\u003cp\u003eThe cone itself is a curvilinear shape — not a standard straight-sided cone. The curved profile is inherently more rigid across all axes, with a reinforcing rib at the rim for extra strength. No cone flexing, no breakup, no harsh distortion — just clean, accurate bass at any volume.\u003c\/p\u003e\n\u003cp\u003eTo take it even further, the aluminum alloy is electrochemically strengthened with a hard sandwich of aluminum oxide ceramic. This constrained-layer construction makes the cone significantly more rigid than competitive designs, while also providing permanently anodized colors that are bright, weatherproof, and scratch-resistant.\u003c\/p\u003e\n\u003ch3\u003eFerrofluidic Motor Structure\u003c\/h3\u003e\n\u003cp\u003eDistortion kills clarity. The Alchemy MX Free-Air uses a Ferrofluid-cooled motor assembly that keeps the voice coil running cool while virtually eliminating harmonic distortion. The result is bass that stays clean and controlled, even during long listening sessions at high output.\u003c\/p\u003e\n\u003ch3\u003eAero-Vented Cast Alloy Frame\u003c\/h3\u003e\n\u003cp\u003eThe cast alloy frame provides a rock-solid foundation that eliminates unwanted resonance, while Alumapro's proprietary aero-venting channels airflow beneath the spider to reduce turbulence noise. In a free-air install where the back of the sub is exposed to the trunk space, proper venting is critical — the MX frame is designed for exactly this kind of open-air environment.\u003c\/p\u003e\n\u003ch3\u003eSantoprene Rubber Surround\u003c\/h3\u003e\n\u003cp\u003eThe high-roll Santoprene surround delivers smooth, linear excursion across a wide temperature range. Whether it's a freezing Chicago winter or a summer road trip, this surround performs consistently — delivering reliable bass and long-term durability season after season.\u003c\/p\u003e\n\u003ch3\u003eLaminated Nomex Suspension\u003c\/h3\u003e\n\u003cp\u003eThe dual-layer Nomex spider keeps the cone centered with precision, maintaining linear movement even at high excursion levels. In a free-air setup where there's no enclosure air spring to help control the cone, a well-engineered suspension system is everything — and the MX gets it right.\u003c\/p\u003e\n\u003ch3\u003eBuilt for Your Setup\u003c\/h3\u003e\n\u003cp\u003eThe Alchemy MX 12\" Free-Air is designed for infinite baffle and vented enclosure applications. Perfect for trunk wall mounts, rear deck installs, custom baffles, and vented boxes tuned at 30–36 Hz. Available in Single 4-ohm, Single 8-ohm, Dual 4-ohm, and Dual 6-ohm voice coil configurations, giving you flexibility in how you wire your system — and make it easy to add multiple MXs down the road.\u003c\/p\u003e\n\u003cp\u003eAvailable in Silver, Frost, Black, and Custom cone colors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHand-built in Huntley, Illinois by Alumapro.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Alumapro","offers":[{"title":"Single 4 ohm \/ Silver","offer_id":52374285320481,"sku":"120413-B04F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Single 4 ohm \/ Frost","offer_id":52374285353249,"sku":"120413-B05F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Single 4 ohm \/ Black","offer_id":52374285386017,"sku":"120413-B06F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Single 4 ohm \/ Custom","offer_id":52374285418785,"sku":"120413-B0_F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 4 ohm \/ Silver","offer_id":52374285451553,"sku":"124413-B04F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 4 ohm \/ Frost","offer_id":52374285484321,"sku":"124413-B05F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 4 ohm \/ Black","offer_id":52374285517089,"sku":"124413-B06F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 4 ohm \/ Custom","offer_id":52374285549857,"sku":"124413-B0_F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 6 ohm \/ Silver","offer_id":52374285582625,"sku":"126613-B04F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 6 ohm \/ Frost","offer_id":52374285615393,"sku":"126613-B05F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 6 ohm \/ Black","offer_id":52374285648161,"sku":"126613-B06F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Dual 6 ohm \/ Custom","offer_id":52374285680929,"sku":"126613-B0_F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Single 8 ohm \/ Silver","offer_id":52374285713697,"sku":"120813-B04F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Single 8 ohm \/ Frost","offer_id":52374285746465,"sku":"120813-B05F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Single 8 ohm \/ Black","offer_id":52374285779233,"sku":"120813-B06F","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Single 8 ohm \/ Custom","offer_id":52374285812001,"sku":"120813-B0_F","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/1145\/9873\/files\/PXL_20250523_013015862.RAW-01.MP.COVER.jpg?v=1772152103"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/1145\/9873\/collections\/PXL_20260306_222938618.RAW-01.MP.COVER.png?v=1773200864","url":"https:\/\/www.shopalumapro.com\/collections\/alchemy-mx.oembed","provider":"ShopAlumapro.com","version":"1.0","type":"link"}
