Equipped with a massive 18-inch woofer and an oversized 99.2mm voice coil, this sub is built to handle sustained sub-bass notes without choking. It hammers out a massive 134dB Max SPL, giving you the necessary headroom for large halls, marquee weddings, and heavy electronic dance floors. Despite its intimidating output and solid construction, the built-in 24-bit DSP keeps the bass incredibly tight, articulate, and completely musical—no annoying, muddy cabinet drone here, just pure, chest-thumping impact.\u003c\/p\u003e\n\u003ch2 data-path-to-node=\"7\"\u003eWhy Choose the Studiomaster Vortex 18SA Active Subwoofer?\u003c\/h2\u003e\n\u003cul
