@elliottbnewcombjr that is true BUT there are so many other things in a listening space that impact the frequency response and overall sound of the room/speaker that a couple of small woofers don't really make a discernible (or measurable impact).
In any case, I have thick leatherette covers for the woofer boxes of the Cambridge which stay there except for my kids usage (when they remember to remove them).
I tuned the room (passive treatments) with this in mind. My bigger concern is the behavior of the large drivers and radiators on the pair of subwoofers, the 2x12 cabinet for my electric guitar and the echoes and resonance created by my acoustic and Spanish guitars (thus they stay inside their cases). 2x12 is also covered in thick leatherette.
