{"product_id":"eaw-sb528zr","title":"EAW SB528ZR 2 x 18in 1400W Passive Subwoofer (Black)","description":"\u003cp\u003eThe EAW SB528zR is a high-output, 1400W passive subwoofer designed to deliver deep, impactful bass for the most demanding professional applications. As part of EAW's prestigious SB series, the SB528zR features dual 18-inch drivers housed in a vented, optimally tuned enclosure, delivering low-frequency extension and high output typically associated with much larger subwoofers. This versatile, large-format subwoofer is ideal for both portable and permanent installations, providing the deep, \"fatter\" bass sound desired in applications such as concert touring, large houses of worship, arenas, f\/x reinforcement, cinemas, large auditoriums, and large dance clubs. Its compact size relative to its power output makes it suitable for installations where space is limited but bass impact is critical.\u003c\/p\u003e\n\u003cp\u003eThe SB528zR is engineered for high-performance, with two 18-inch drivers that handle up to 1000W of continuous power (AES) each. The direct radiating design ensures that the subwoofer produces clean, powerful bass without distortion. Its operating frequency range of 27 Hz to 147 Hz ensures extended low-end reproduction that complements a wide variety of full-range loudspeakers. The subwoofer achieves impressive SPL levels, including an average SPL of 129 dB (whole space) and 135 dB (peak, whole space), and 135 dB (average) and 141 dB (peak) in half space. This level of output makes it well-suited for large-scale applications, providing plenty of punch for bass-heavy events or sound installations that require high levels of dynamic impact.\u003c\/p\u003e\n\u003cp\u003eDesigned with flexibility in mind, the SB528zR can be configured for either single-amp or dual-amp operation, allowing it to be used in a variety of system setups. The nominal impedance is 4 ohms per driver, with a minimum of 3.9 ohms at 131 Hz, ensuring compatibility with most professional amplifiers. For optimized low-frequency performance, EAW recommends using their MX Series processors for proper crossover and equalization. The recommended high-pass filter at 25 Hz with a 12 dB\/octave Butterworth slope ensures that the subwoofer operates within its ideal frequency range while protecting the drivers from unwanted frequencies. The subwoofer is designed to operate reliably even in the most challenging conditions, handling up to 1400W of power and delivering consistent performance for the long term.\u003c\/p\u003e\n\u003cp\u003eThe SB528zR's construction includes an enclosure made of Baltic birch plywood, which enhances both durability and resonance control, ensuring that the subwoofer performs optimally over time. The wear-resistant textured black paint finish provides a sleek and professional appearance, while the powder-coated perforated steel grille protects the drivers from damage while maintaining optimal sound dispersion. With dimensions of 30.19 x 50.69 x 24.56 inches and a weight of 215 lbs, the SB528zR is a substantial subwoofer that delivers the bass performance needed in large venues and demanding environments. Its 360-degree coverage ensures that bass is evenly distributed throughout the space, making it ideal for large venues or events where consistent bass reproduction is required across the entire listening area.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1400W passive dual 18-inch subwoofer designed for high-output, deep bass reproduction\u003c\/li\u003e\n\u003cli\u003eOptimally tuned, vented enclosure for efficient low-frequency performance and minimal distortion\u003c\/li\u003e\n\u003cli\u003eOperating range from 27 Hz to 147 Hz, providing deep sub-bass and controlled mid-bass reproduction\u003c\/li\u003e\n\u003cli\u003e360° horizontal and vertical beamwidth for even bass coverage across the entire venue\u003c\/li\u003e\n\u003cli\u003eMaximum SPL of 141 dB (peak) in half space and 135 dB (peak) in whole space for high-impact bass\u003c\/li\u003e\n\u003cli\u003eNominal impedance of 4 ohms per driver with a minimum impedance of 3.9 ohms at 131 Hz\u003c\/li\u003e\n\u003cli\u003eWorks with EAW MX Series processors for optimal DSP crossover and equalization\u003c\/li\u003e\n\u003cli\u003eRecommended high-pass filter at 25 Hz with 12 dB\/octave Butterworth slope for system protection\u003c\/li\u003e\n\u003cli\u003eIdeal for large houses of worship, arenas, concert touring, cinemas, large auditoriums, and dance clubs\u003c\/li\u003e\n\u003cli\u003eDurable Baltic birch plywood enclosure with wear-resistant textured black finish\u003c\/li\u003e\n\u003cli\u003ePowder-coated perforated steel grille for driver protection and optimal sound dispersion\u003c\/li\u003e\n\u003cli\u003eDimensions: 30.19 x 50.69 x 24.56 inches; Weight: 215 lbs for reliable performance in large installations\u003c\/li\u003e\n\u003cli\u003eIncludes 2 x Neutrik NL4 connectors and 2-pin barrier strip for flexible connectivity options\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ch3\u003eConfiguration\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubsystem: 2 x 18-inch cone, vented\u003c\/li\u003e\n\u003cli\u003eOperating Mode:\n\u003cul\u003e\n\u003cli\u003eSingle-amp LF1\/LF2\u003c\/li\u003e\n\u003cli\u003eDual-amp LF1, LF2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eAmplifier Channels: LF1\/LF2\u003c\/li\u003e\n\u003cli\u003eExternal Signal Processing: DSP w\/1-way filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePerformance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Range: 27 Hz to 147 Hz\u003c\/li\u003e\n\u003cli\u003eNominal Beamwidth: Horizontal 360°, Vertical 360°\u003c\/li\u003e\n\u003cli\u003eAxial Sensitivity (SPL):\n\u003cul\u003e\n\u003cli\u003eLF1\/LF2 (whole space): 97 dB (27 Hz to 147 Hz)\u003c\/li\u003e\n\u003cli\u003eLF1\/LF2 (half space): 103 dB (27 Hz to 147 Hz)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eInput Impedance (ohms):\n\u003cul\u003e\n\u003cli\u003eLF1\/LF2 (Nominal): 4\u003c\/li\u003e\n\u003cli\u003eLF1\/LF2 (Minimum): 3.9 @ 131 Hz\u003c\/li\u003e\n\u003cli\u003eLF1, LF2 (each, Nominal): 8\u003c\/li\u003e\n\u003cli\u003eLF1, LF2 (each, Minimum): 7.8 @ 131 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eRecommended High Pass Filter: High Pass =\u0026gt; 25 Hz, 12 dB\/octave Butterworth\u003c\/li\u003e\n\u003cli\u003eAccelerated Life Test:\n\u003cul\u003e\n\u003cli\u003eSystem (LF1\/LF2): 75V (1400 W @ 4 ohm)\u003c\/li\u003e\n\u003cli\u003eLF1, LF2 (each): 75V (700 W @ 8 ohm each)\u003c\/li\u003e\n\u003cli\u003eTransducer (AES): 1000W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eCalculated Axial Output Limit (SPL):\n\u003cul\u003e\n\u003cli\u003eLF1\/LF2 (whole space): 129 dB (Average), 135 dB (Peak)\u003c\/li\u003e\n\u003cli\u003eLF1\/LF2 (half space): 135 dB (Average), 141 dB (Peak)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEnclosure\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Baltic birch plywood\u003c\/li\u003e\n\u003cli\u003eFinish: Wear resistant textured black paint\u003c\/li\u003e\n\u003cli\u003eGrille: Powder-coated perforated steel\u003c\/li\u003e\n\u003cli\u003eDimensions (HWD): 30.19 x 50.69 x 24.56 inches\u003c\/li\u003e\n\u003cli\u003eWeight: 215 lbs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAW","offers":[{"title":"Default Title","offer_id":49010294325497,"sku":"SB528ZR","price":5973.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/eaw_new_sb528z-black_4c32a09d-ecc9-4b06-9647-add88a60fcec.jpg?v=1788564580","url":"https:\/\/blackoutaudio.com\/products\/eaw-sb528zr","provider":"Blackout Audio","version":"1.0","type":"link"}
