FWIW, I always find it interesting when people complain about the lack of bass (32hz+) in the 63's and 988's. Most often these are the same folks who say the speakers sound best when they are elevated 8 to 12 inches off the floor (which would reduce the bass in any speaker, box or stat due to a change in the floor reflections which reinforced the bass when they were on the floor.)
Peter Walker designed the Quad 63's to be on the floor (he later changed is mind but I think this change was more about sales than sonics.
A well set up 63 or 988, on the floor, will produce a very tight and flat bass down to the mid 30's and it does not screw up the mid-range, it just fleshes it out. I had full range boxes and 63's in my room which measured exactly the same when the Quads were on the floor and the imaging was not effected either. Off the floor (I have stands for the Quads) they sound brightish and enemic.
Just some more stuff to think about..........
