Review on 🔈 OSD Audio SMP1000DSP Mono Subwoofer Amplifier with DSP Control, LED Screen - 1000W Class D by Marco Cervantes

I received this OSD SMP-100 subwoofer amp on January 9th 2020, after looking at various models this one seemed to be the to be the most reasonable. After hooking it up and testing, this amp turned out to be exactly what I needed to add to my home audio system. This subwoofer works great in conjunction with my receiver and 8-speaker 4-zone selector for my ceiling speakers with a separate 8" non-passive, active subwoofer when this little amp is rated at 80 RMS 100 when properly connected and configured Watts of power into 4 ohms can deliver enough power to shake my whole house at a quarter the volume from watching a movie or playing music, it's very clear sound with no background feedback, it has a phase control to adjust the subwoofers -Placement, a crossover control so you can adjust and set the low pass to the level you want and the master volume control to the volume you want. It turns off automatically after 15 minutes if no audio signal is detected, so you don't have to turn it on and off manually. I recommend not using speakers larger than 8 inches with an impedance of 4 to 8 ohms as stated in the manual. Once properly tuned, this little amp produces clean, deep bass without being out of phase with your system. This subwoofer can also be used to power a passive in-wall subwoofer such as the IWS 8 OSD series which I will be using later.
