I am getting this wrong?
If I take a driver of a certain quality, and can guarantee a consistency of that quality so my results are consistent, and work with it over a number of years so I know it inside out, then apply DSP I've developed to correct any imperfections I don't want, then don't I counter the need for all-singing-and-dancing driver (as found in an exotic passive speaker)?
If the above (of course, simplified) argument is correct the Meridian would have a whole shed load of extra work to do if they changed drivers.
