Monitor speakers on top of subs

I came across a very smart isolating concept some years, in a retail speaker: the low bass drivers were in a completely separate cabinet, but the overall design made it appear as if they were indeed integrated. Visually it worked nicely; the reality was that the drivers handling the higher frequencies were in a box which was firmly sitting on the floor, so one could make the mating between that cabinet and floor be whatever one wanted.

As Ralf states, stabilising the drivers so they don't wobble about is critical; expensive commercial speakers make it happen by using very inert, heavy cabinets - if you don't want to pay the money that this will cost you, simply make the value for money speakers that are available have effectively the same qualities. Reasonable drivers in a boringly standard shoebox were made to deliver an intense pipe organ presentation decades ago, by following this procedure - the goal is make the cabinet, no matter how flimsy it is intrinsically, feel as if it's immensely solid when you lightly push on it, from any angle.
