LOOK AT D SPECS BAI AN COMPARE THEM FOR YOURSELF. THE b&c 10md 26 WRKING BETWEEN 80Hz - 4.0kHz AN THE RCF 70 Hz-3000Hz b&c Sensitivity 100dB, RCF 100 dB b&c Resonant Frequency 78 RCF 68 BOTH SPEAKER HAVE THE SAME POWER RATING DO THE MATHS..
I have both of these drivers and I hooked them up to my soundstream tx2.1500 to see the difference, and all I can say is, there is not that much of an audible difference with them playing...sound almost the same to me. Keep in mind everyone's listening taste is different. Only thing I could seem to find different about these was the RCF having a higher xmax at 2.5mm
