My friend has these and uses them on his patio (actually, they're in the living room, but he puts them by the window and points them at us while grilling). In general, sound is good enough for the price, but it's easy to see why the price is what it is. The panels on the cabinet aren't 3/4in thick, and these are relatively large cabinets - they pound more bass but my smaller Swans D1080MkII 08 had cleaner bass, and not that much less in quantity. Basically between these two (or whatever version the D1080 is at right now) I'd choose the Swans - they don't use 3/4in MDF except in the front baffle but the smaller cabinets make that less of a problem. Cabinets look nicer too, and does better on the knock test.
Apart from that, it depends on whether you can get them in your area - our local brick and mortar dealer was more reliable than internet dealers after Swans changed to other dealers. If you're in N.America, I'm not sure if they've already set up a new dealer network (despite the fact that their design/engineering outfit is somewhere in California), so it might be better to go with the 5in Monoprice monitors (you can find them on the Monoprice website).
