It is not that simple. Your speakers are fairly flat on axis. The BBC dip occurs off axis - with greater dip at greater angles. It comes from using a woofer that is too large for the midrange (a 5 inch or more and running it up to nearly 4 Khz, where it "beams" severely - just like B&W use).
Think of your speakers mid range as a narrow beam flashlight - sure you can put in higher power batteries to raise the overall brightness to compensate for the narrow beam, however, this makes the narrowest part of the beam particularly intense and may be a problem even if the room is better lighted overall.
Besides most people prefer the BBC Dip, which is why so many speakers are made this way. B&W are a great company and they know what they are doing (making speakers sound teh way people like them to sound)
