Our U.S.-based research, development, and design team is supported by a network of cutting-edge acoustical, mechanical, and electrical engineers. Together, we create products that combine the latest technology with ease of use for a quality sound experience.
High Current Power
The amplifiers are 4 ohm stable, which doubles the current demand output and can power two 8 ohm subwoofers wired in parallel.
The phase control operates over a range of 0 to 180 degrees and compensates for a delay between the subwoofer and the main speakers.
The advanced crossover circuit can be set at different frequency ranges (35Hz to 160Hz) and can be adjusted with the front-panel control knob.
Class D Digital Amplifier Technology
Highly efficient Class D technology runs cool under demanding loads and doesn’t take up a lot of space.

Our SMP100 Class D digital subwoofer amplifier is a compact 100W amp designed to power passive subwoofers used in home theaters or whole house audio systems. We call this our “tiny but mighty” powered sub because it measures less than six inches wide but supplies an in-wall or stand-alone subwoofer the power it needs so you can experience room-shaking low frequency impact (bass) on movie and music soundtracks.
Ideal for powering subwoofers used in whole-house audio or home theaters Highly efficient Class D technology runs cool under demanding loads Adjustable low-pass filter for distortion-free bass
