D B TECHNOLOGIES
The dBTechnologies SUB 18H is a high-performance active subwoofer featuring a unique Hybrid Horn-Loading configuration designed to combine low-end extension with acoustic efficiency. Equipped with a high-excursion 18-inch woofer, a 1500W RMS Digipro G3 Class-D amplifier, and a 56-bit DSP engine, it delivers high sound pressure levels and precise low-frequency reproduction for live sound applications and venue installations.
The dBTechnologies SUB 18H is a high-performance, semi-horn-loaded active subwoofer designed to deliver deep, enveloping low-frequency extension for small- to mid-sized live events, portable PA setups, clubs, ballrooms, and theatrical installations. Utilizing an innovative Hybrid Horn-Loading configuration, it optimizes efficiency to convey massive low-end performance even at close listening distances.
Hybrid Horn-Loading & Acoustic Excellence
Equipped with a powerful 18” woofer featuring a robust 4” voice coil, the SUB 18H is engineered to tune into the lowest frequencies while maintaining exceptional system efficiency. Unlike conventional horn-loaded subwoofers, this unique design ensures superior acoustic projection and tight transient response across demanding audio environments.
Digipro® G3 Amplification & Advanced DSP Processing
Driven by a lightweight and highly efficient 1500 W RMS (2000 W peak) Digipro G3 Class-D amplifier, the system delivers a max SPL of up to 134 dB. Onboard processing features a 56-bit DSP with 24-bit / 48 kHz AD/DA conversion, offering dual active limiters (RMS, Peak, Thermal), selectable crossover frequencies (90 Hz or 120 Hz at 24 dB/octave), phase inversion switching, and a built-in delay switch of up to 4.5 ms (adjustable in 0.5 ms steps).
Tour-Ready Build & Smart Telemetry
Housed in sturdy birch plywood with a black PVC cover and durable polypropylene edges designed to resist scratches and impacts during transit, the cabinet features exclusive aluminum heavy-duty handles and a standard M20 pole mount plate on top. Additionally, a mini USB Type-B port allows for firmware updates and telemetry logging to track amplifier status and usage history.
