Yamaha DXS18 MK3 18" Band-Pass Active Subwoofer, 1250W
The Yamaha DXS18 MK3 is the flagship 18" 1250W Band-Pass Active Subwoofer in the DXS MK3 series, delivering 134dB peak SPL and 2500W Class-D amplification, featuring D-XSUB processing with extended low-frequency response down to 32Hz, Bluetooth 5.0 and wireless remote control.
The Yamaha DXS18 MK3 is the largest and most powerful model in Yamaha's latest generation of DXS series powered subwoofers, delivering the deepest low-frequency extension, the highest peak SPL and the most authoritative bass performance in the entire DXS MK3 range.
Built around a proprietary 18" high-durability transducer with a 4" voice coil — the largest driver in the DXS MK3 series — a newly developed 2500W Class-D amplifier and an ideal bandpass cabinet structure that eliminates unwanted cabinet noise, the DXS18 MK3 provides the ultimate low-frequency foundation for the most demanding professional live music, DJ events, festival performances and large-scale events where maximum bass output, depth and impact are non-negotiable. When paired with the DXR MK3 series loudspeakers, the DXS18 MK3 enables users to build a seamlessly integrated and perfectly matched sound system with truly unparalleled impact.
Maximum Performance Bandpass Design
The DXS18 MK3's acoustically optimised bandpass cabinet design delivers the deepest and most powerful bass performance in the DXS MK3 range. The 18" driver with 4" voice coil — a larger voice coil than the 3" units found in the DXS12 MK3 and DXS15 MK3 — provides greater thermal capacity, higher excursion capability and the ability to sustain very high output levels over extended periods without degradation. Housed in a durable, acoustically optimised plywood cabinet with scratch-resistant Polyurea coating, the bandpass enclosure maximises bass output efficiency and eliminates unwanted cabinet noise and resonances for tight, clean and impactful low-frequency reproduction at the highest output levels. The result is a peak SPL of 134dB — the highest in the DXS MK3 range — with low-frequency extension reaching down to 32Hz in XTENDED LF mode for the most demanding bass-heavy applications.
D-XSUB Processing & Advanced DSP
The DXS18 MK3 is equipped with onboard 32-bit/96kHz DSP including Yamaha's proprietary D-XSUB processing, which extends the low-frequency response down to an exceptional 32Hz in XTENDED LF mode — the deepest extension in the DXS MK3 series — for applications demanding the most profound and impactful bass reproduction available. Extremely flexible crossover settings are available via the DSP, with a selectable HPF between 50Hz and 118Hz at 12–48dB/octave for precise integration with full-range loudspeakers across different system configurations. A cardioid mode provides effective bass management for on-stage applications, reducing low-frequency energy behind the subwoofer for cleaner stage sound and more controlled and focused front-of-house bass projection.
Flexible Control & Connectivity
Two combo input connectors accept balanced and unbalanced sources at up to +24dBu, whilst two XLR outputs provide thru and DSP out options for seamless integration with full-range loudspeakers in a complete system. Bluetooth 5.0 (A2DP, SBC/AAC, Class 1) enables wireless audio streaming from smartphones and compatible devices. The D-Remote app for iOS and Android provides full wireless remote control of all DSP parameters, monitoring and system management for up to ten devices simultaneously with grouping for unified level and mute control. Five-speed fan cooling ensures optimal amplifier temperature throughout extended high-power use.
Practical Design & Deployment
The DXS18 MK3's durable plywood cabinet with Polyurea coating provides excellent long-term reliability in demanding professional environments. Two side handles assist with positioning and handling of this substantial cabinet, whilst dual pole sockets — a 35mm socket (80mm depth) and an M20 threaded socket (25mm threaded depth) — provide flexible satellite speaker mounting options for full-range loudspeakers such as the DXR MK3 series. Given the DXS18 MK3's size and weight of 51kg, the optional speaker wheel kit (SPW-1) is a highly practical accessory for transport between venues, alongside the optional speaker cover (SPCVR-DXS183) for protection during storage and outdoor use.
