A 1400W Class-D amplifier drives the high-performance 18-inch woofer, delivering up to 132 dB maximum SPL with low-frequency performance extending down to 33 Hz.\u003c\/p\u003e\n\u003cp\u003eSelectable high-pass modes make system integration particularly easy. Dedicated presets are available for Thump12V4, Thump15V4 and Thump GO loudspeakers, while a Variable mode allows the crossover to be adjusted for use with other speaker systems. Each preset incorporates alignment delay to help maintain proper timing between the subwoofer and connected main speakers.\u003c\/p\u003e\n\u003cp\u003eStereo XLR inputs accommodate mixers, DJ controllers and other professional sources. Separate stereo high-pass outputs feed the main loudspeakers with the selected crossover applied, while full-range XLR outputs make it easy to daisy-chain additional subwoofers. Phase inversion, stereo\/mono summing and variable output level provide further control for different room layouts and system configurations.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e18in professional powered subwoofer\u003c\/li\u003e\n\u003cli\u003e1400W Class-D amplification\u003c\/li\u003e\n\u003cli\u003eUp to 132 dB maximum SPL\u003c\/li\u003e\n\u003cli\u003eLow-frequency response down to 33 Hz\u003c\/li\u003e\n\u003cli\u003eHigh-performance 18in woofer\u003c\/li\u003e\n\u003cli\u003eThump12V4 140 Hz crossover preset\u003c\/li\u003e\n\u003cli\u003eThump15V4 110 Hz crossover preset\u003c\/li\u003e\n\u003cli\u003eThump GO 150 Hz crossover preset\u003c\/li\u003e\n\u003cli\u003eVariable crossover mode\u003c\/li\u003e\n\u003cli\u003e1.4 ms alignment delay in high-pass modes\u003c\/li\u003e\n\u003cli\u003eStereo XLR inputs\u003c\/li\u003e\n\u003cli\u003eStereo XLR high-pass outputs\u003c\/li\u003e\n\u003cli\u003eStereo XLR full-range outputs\u003c\/li\u003e\n\u003cli\u003ePhase invert switch\u003c\/li\u003e\n\u003cli\u003eStereo or mono summing\u003c\/li\u003e\n\u003cli\u003eVariable level control from mute to +6 dB\u003c\/li\u003e\n\u003cli\u003eSwitchable front LED\u003c\/li\u003e\n\u003cli\u003eM20 threaded speaker-pole mount\u003c\/li\u003e\n\u003cli\u003eIntegrated carrying handles\u003c\/li\u003e\n\u003cli\u003eWeight: 70.4 lb \/ 31.9 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mackie","offers":[{"title":"Default Title","offer_id":46729008971965,"sku":"1061931","price":1229.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/4175\/9421\/files\/1777333657_1955416.jpg?v=1788977174","url":"https:\/\/moogaudio.com\/products\/mackie-thump18sv4-18in-1400w-powered-subwoofer","provider":"Moog Audio","version":"1.0","type":"link"}
