The Stetsom IR 400.1 BASS is built for people who want a compact monoblock that is focused on subwoofer power, bass control, and clean low-end output without taking up much room. This amplifier is part of the Iron Line and is designed specifically for bass applications, making it a strong fit for smaller subwoofer setups, budget-friendly daily systems, and installs where space is limited but real bass still matters. Stetsom positions it as a compact, high-performance amplifier that delivers deep, punchy low-end sound while maintaining 4K Ultra HD audio quality.
Rated at 400 watts RMS at 2 ohms, the IR 400.1 BASS is made for customers who need dependable monoblock power in a small chassis. It is engineered for subwoofer and bass-focused sound systems, and the page also highlights more defined mids and cleaner highs along with strong bass output. In real-world terms, that means this amp is a good option for someone building a compact bass setup that still needs control and solid everyday performance.
One of the best things about this amp is how useful the tuning section is for a small bass amplifier. Stetsom includes a low-pass filter from 35 Hz to 250 Hz, a high-pass filter from 5 Hz to 35 Hz, and bass boost up to +15 dB with adjustable frequency from 35 Hz to 60 Hz. The page also calls out a reinforced internal power supply for enhanced bass response and high-quality connectors with Cable Insulation Guide, which helps make this a practical amp for tighter installs where reliability matters just as much as output.
Whether you are powering a compact subwoofer setup, upgrading an OEM-style system with real low-end authority, or putting together a clean daily bass build on a practical budget, the Stetsom IR 400.1 BASS gives you focused subwoofer power, useful crossover control, and a size that is easy to work with.
