I had a couple extra htm-200se and found a small fosi amp to drive them in a small room. Sounds really good but Thinking of getting a small sub for music. Fosi doesn’t have a sub out just a preout. Anyone with experience using sub’s crossover and sound meter to get htm200se to mate to them? Didn't find any threads on this. Trying to figure out if that will work well or I need a different receiver/preamp.
