BASSBOSS ZV28-MK3 - 5000W 2 x 18-inch Powered Vented Direct Radiating Subwoofer with 4-inch Voice Coils and 360-Degree Coverage in Black Finish

The BASSBOSS ZV28-MK3 subwoofer is a powerhouse designed for those who seek an unparalleled low-frequency experience. With its dual 18-inch Neodymium motor woofers and exceptional design, the ZV28-MK3 delivers smooth, deep, and effortless bass that is felt as much as it is heard. Designed to meet the needs of touring professionals, DJs, and venue owners, this subwoofer offers incredibly low-frequency output, extending down to 23 Hz (+3 dB), far lower than many other subwoofers in its class. The ZV28-MK3 is engineered to provide sustained, high-output performance with minimal distortion, ensuring that even the most demanding events are powered by the finest bass performance.

At the heart of the ZV28-MK3's performance is a 5000W amplifier, providing 2500W to each of the dual 18-inch woofers. The amplifier features an auto-sensing, globally compatible power supply capable of operating on voltages from 90V to 250V, ensuring maximum output at any location. With peak output voltages capable of delivering intense SPL hits, the ZV28-MK3 consistently produces deep, liquid lows with remarkable accuracy and power. The amplifier is passively cooled through its external heat-sink and woofer-generated air-flow, but when needed, two axial fans engage to provide additional cooling capacity in more extreme conditions.

The woofers in the ZV28-MK3 are equipped with massive 4-inch (100mm) voice coils and neodymium motors, resulting in a lightweight yet highly efficient subwoofer. Neodymium magnets provide high efficiency, reducing the cabinet's weight while maintaining superior sound quality. The cabinet itself is crafted from 18mm Baltic Birch plywood, extensively braced to reduce resonance and ensure durability. The ZV28-MK3's design also includes innovative features like anti-standing wave baffles and pass-through dampers to minimize upper resonances and deliver smooth, distortion-free bass.

One of the most striking features of the ZV28-MK3 is its deep, clean, and flat frequency response. The subwoofer's natural response from 23 Hz to 90 Hz is achieved without the need for bass-boost EQ, maintaining high output at lower frequencies with remarkable efficiency. Unlike other subwoofers that rely on EQ to achieve their claimed performance, the ZV28-MK3's design ensures that it delivers what it promises in real-world conditions, even at maximum power. This ensures consistent, powerful bass with minimal thermal compression, keeping the subwoofer running at full throttle without compromising sound quality.

The ZV28-MK3 is versatile, allowing for different setup options based on your needs. It features dual 35mm pole sockets, enabling you to mount the subwoofer either horizontally or vertically. This flexibility allows you to stack smaller top cabinets on the subwoofer or use it for front-fill applications. With its compact design, the ZV28-MK3 provides high-output, low-frequency performance while taking up minimal space, making it ideal for venues with limited room. For mobile setups, the subwoofer's interlocking feet allow for secure stacking, and it can be transported easily with the optional transport dolly, which accommodates up to four units for tight truck-packing efficiency.

Equipped with BASSBOSS's latest DSP, the ZV28-MK3 includes multiple preset options, high-pass and low-pass filters, phase alignment, and comprehensive protection systems. The DSP's advanced limiter technology ensures that the subwoofer remains within its safe operating parameters, preventing driver overload and protecting against thermal and excursion issues. The five levels of protection operate independently, ensuring the subwoofer can achieve peak output with minimal effect on transient response. The DSP also features an Ethernet interface for easy control via a computer, with the ability to send signals over Milan AVB, update firmware, and monitor signal levels and temperatures. Up to 100 presets can be stored, eight of which are directly accessible without a connected computer.

With its robust construction, high-output capabilities, and versatile setup options, the BASSBOSS ZV28-MK3 is a subwoofer that can handle demanding live events, installations, and mobile applications. Whether you need deep bass in a compact space or the raw power to fill large venues, the ZV28-MK3 delivers exceptional performance in every setting. Its durability, flexibility, and ease of use make it a top choice for professionals who need reliable, high-quality bass reproduction on the go.
