The B22
Subwoofer: Powerhouse Performance for Professional Audio Reinforcement Engineered for the most demanding environments, the B22 Subwoofer delivers exceptional low-frequency response and sonic clarity that elevates any live sound system. As a cornerstone in professional audio setups, this dual 18-inch long-stroke bass solution is meticulously designed to enhance stage presence, improve audience immersion, and ensure consistent performance across large venues—from concert halls to outdoor festivals. Key Features: - Dual 18-inch high-excursion drivers for deep, impactful bass - Bandpass horn cabinet design maximizing SPL efficiency (up to 143 dB) - INFRA mode compatibility with other d&b subwoofers for extended low-end extension - Cardioid array capability when using multiples of three units—reducing rearward energy and minimizing interference with monitor speakers - Rugged marine-grade plywood enclosure with durable impact-resistant coating - Metal front grille and breathable foam back panel for protection without compromising acoustics - Integrated handles and heavy-duty wheels for effortless mobility - Precision stacking rails and top grooves for secure vertical arrangement In-depth Description: The B22 Subwoofer represents a significant advancement in sub-bass technology, offering both raw power and intelligent acoustic control. Its dual 18-inch drivers are engineered for high excursion and thermal stability, ensuring sustained performance even under extreme conditions. The bandpass enclosure design optimizes air flow and minimizes distortion, resulting in cleaner output at higher volumes. With an impressive frequency range tailored for deep bass reproduction, it serves as the ideal complement to line array systems or standalone installations where precision low-end reinforcement is critical. One standout feature is its INFRA mode, which allows seamless integration with other d&b subwoofers like the V-Series, effectively extending the system’s lower limit—making it particularly effective in cinematic, theatrical, and immersive sound applications. Additionally, deploying three or more B22 units in a cardioid configuration enables directional control of bass energy, significantly reducing unwanted spill behind the stage while maintaining full coverage in the listening area. This makes it an essential tool for engineers seeking clean stage monitoring and optimized audience experience. Built for real-world use, the B22’s marine plywood cabinet resists wear from frequent setup and teardown, while the reinforced handles and casters simplify transport across uneven terrain. The internal structure ensures no rattles or resonances during operation, and the robust grille protects sensitive components without dampening sound quality. Ideal Applications: This subwoofer excels in professional touring sound, permanent installations in clubs and arenas, corporate events, and large-scale outdoor concerts. Whether integrated into a complete d&b line array system or used independently, it provides reliable performance in fixed installations or mobile rigging scenarios. It’s especially well-suited for event production teams looking to balance powerful bass delivery with minimal logistical complexity. User Feedback: Users consistently praise the B22 for its ability to deliver punchy, controlled lows even in high-SPL environments. Many note how its cardioid mode reduces feedback issues on stage, allowing performers to hear themselves clearly without competing with bass-heavy fronts. Touring sound engineers appreciate the durability and ease of handling, while installers value the flexibility in array configurations and the tight integration with d&b digital amplifiers such as the D80, D20, and 30D models. Frequently Asked Questions: What makes the B22 Subwoofer different from consumer-grade subs? Unlike typical home theater or portable subwoofers, the B22 is built for professional deployment—with rugged materials, advanced acoustic engineering, and scalable array capabilities that meet industry standards for live sound reinforcement. Can I use it with non-d&b amplifiers? While recommended for use with d&b digital amps like the D80 for optimal performance, compatible alternatives exist depending on your speaker configuration and amplifier specs. How many B22 units should I use for a cardioid pattern? For a true cardioid effect, you need at least three units arranged in a specific geometry to achieve directional control in the low-frequency spectrum. Is it suitable for indoor and outdoor use? Yes—the durable construction and weather-resistant finish make it ideal for both permanent installations and temporary outdoor setups, provided proper protection from direct rain exposure.
