As you've seen Dave's note by now in another thread - 5Liters would be the lower recommended limit. Due to the size of front baffle the generous bezel flange on this driver dictates, you may need to reduce the depth of cabinet to the point that "cupped" or closed in midrange colorations, most noticeable on voice becomes a big concern. We've found that to be an issue with a wide range of drivers and enclosure topologies - when the box is that small, you definitely hear the box.

FWIW, I presently have 2 pairs of 7s in quite different enclosures - Pensil and Mar-Ken. Each have their own merits - most notable of the Pensil is the ease of build even with bracing, and no need for stands - but both of them much larger than 5 liters.
