{"product_id":"21-lfa-2000","title":"21 LFA 2000","description":"\u003ch3\u003e21 LFA 2000\u003c\/h3\u003e\n\u003cp\u003eMeet the 21 LFA 2000, a flagship 21-inch transducer from the esteemed PRO SERIES. Engineered as a premier acoustic solution for extreme low-frequency reproduction, this high-excursion subwoofer driver serves as the ultimate foundation for custom-built touring rigs and high-impact fixed venue installations. Whether deployed in massive arena line array complements or earth-shaking nightclub bass bins, it is specifically designed by PowerX to deliver unyielding acoustic pressure and structural reliability.\u003c\/p\u003e\n\u003cp\u003eWhen evaluating acoustic output and power handling, this transducer is built to absolutely dominate, boasting a massive 2000 AES Watt continuous capacity alongside an immense 4000 Watt Program Power rating. While the absolute Max SPL will depend on your final enclosure configuration, its ultra-high sensitivity of 99dB (1w @ 1m) guarantees devastating overall loudness and maximized amplifier efficiency out of the box. This exceptional efficiency provides tremendous dynamic headroom, ensuring the speaker maintains absolute clarity, punch, and transient accuracy even when pushed to extreme volumes over grueling two-hour pink noise tests.\u003c\/p\u003e\n\u003cp\u003eThe core of this driver's technology lies in its highly advanced internal motor structure, centered around a gargantuan 150.6mm (6-inch) voice coil. This massive thermal engine is driven by a heavy-duty ferrite magnet structure, yielding exceptional electromagnetic force for precise cone control. To ensure acoustic integrity, the unit utilizes a highly rigid carbon cone, which significantly reduces structural deformation under extreme mechanical stress. When integrated into a properly tuned cabinet, its colossal 21-inch diameter generates the wide, omnidirectional dispersion typical of extreme sub-bass frequencies, guaranteeing phase-accurate coverage across your entire audience area.\u003c\/p\u003e\n\u003cp\u003eAcoustic fidelity is defined by a deep, authoritative frequency response sweeping from a subsonic 30Hz up to 200Hz. This dedicated low-frequency bandwidth produces a highly desirable sonic character—delivering concussive, tight bass that physically moves air while remaining free of muddy, out-of-band resonance. For optimal crossover efficiency and acoustic purity, system engineers can effortlessly integrate this driver with high-mid array elements, crossing it over perfectly within its most linear operating band to maintain pristine, uncolored audio reproduction from the lowest octaves upward.\u003c\/p\u003e\n\u003cp\u003eConstructed for the brutal realities of touring and professional integration, the transducer features a heavily reinforced chassis engineered to mount seamlessly into premium Baltic birch plywood or rugged polymer enclosures. It operates at a nominal impedance of 8 Ohms, making it highly versatile for parallel wiring configurations on standard heavy-duty amplifiers. Weighing in at a substantial 18 Kg, the sheer mass of the assembly is a testament to its relentless build quality. Ready to be hardwired to heavy-duty connectors like NL4 SpeakONs within your custom designs, the 21 LFA 2000 is a road-worthy powerhouse built to deliver uncompromising low-frequency energy night after night.\u003c\/p\u003e","brand":"POWERX PRO","offers":[{"title":"Default Title","offer_id":49687854252184,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/1016\/3096\/files\/21lfa2000-pro.svg?v=1786723971","url":"https:\/\/www.powerx.pro\/products\/21-lfa-2000","provider":"POWERX PRO","version":"1.0","type":"link"}
