I bought a couple of these because my powered sub was drowning out my 6x9's and my 5.25 door speakers. They did not disappoint, brought enough midrange and mid-bass to balance the sound.
I do think however, that I can get more from them. My current amp is sending about 110W RMS, and I'm using the high pass filter. I probably should call DS18 and ask for some advice. Maybe I just need more power, or set the crossover differently, or maybe my hearing is going bad, idk. But they do sound fantastic, and my sub no longer overpowers the mids and highs.
