I purchased these on sale and placed these in a homemade box. Matched up with on old 30w rms, 4ch Pioneer GMH120 amplifier and a new Pioneer DEH-S7200BHS head, with some adjustments, I am impressed. To be fair, I did not want to give less or more than 4 stars because of something that could be my error. I had to use the crossover feature on the head unit to produce what I thought was the best sound. I narrowed the range of frequency being sent to the speakers which is below the range advertised for these RK1-169.

Great speakers, they have excellent response. Bass is thumping and the voice is clear, I'm happy with my purchase
Pros: Sound clear with plenty of bass, no distortion
