The HTM-1 is the monoblock model in Wet Sounds’ HTM Series amplifier range — a dedicated single-channel Class-D amplifier engineered for high-power subwoofer applications in demanding marine environments. With 500W at 4Ω, 800W at 2Ω, and 1,200W at 1Ω, the HTM-1 delivers serious subwoofer output in the compact, reduced-height HTM chassis.
Class-D topology delivers superior efficiency and extreme power output without the heat and bulk of traditional amplifier designs, while the 105dB signal-to-noise ratio ensures clean, detailed bass reproduction at any output level. Full-range audio capability and selectable crossovers — high-pass, low-pass, and full range — provide flexibility across different system configurations, and the adjustable crossover range of 50Hz to 500Hz covers the majority of subwoofer and speaker applications. The dedicated subsonic filter, adjustable from 10Hz to 55Hz, removes unwanted sub-bass frequencies that consume power without contributing to audible output — protecting your subwoofer and maximising efficiency.
The reduced-height chassis fits into tighter installation spaces than previous HTX models without sacrificing output or features. Removable power and speaker connectors simplify installation and future maintenance, and the versatile blue LED backlit badge can be mounted horizontally or vertically to suit the installation. Optional mounting feet allow elevation from the mounting surface for additional airflow and installation flexibility. IPX5 water resistance ensures reliable performance in the marine environment. Backed by Wet Sounds’ 2-year warranty.
