Which Dynaudio to buy under 2k used

I think the Contour line offers the best value.

I'm partial to monitors over floorstanders in general in this price range. Add a sub later but only if needed.

The 1.3 mkIIs are very fine and well reviewed monitors. They work best on very solid stands and can be had for well under $2K which leaves room for the stands to go with them.

Mine cost me about $1200 with matching Dyn stands on ebay a couple years back.

They are rear ported though and generally work best when placed well out away from walls. That can be a problem in some rooms.

Also note that these Dyns tend to like lots of power so they are not the best choice for low powered amps. I think the McCormick would be an ideal match though!

"I wouldn't use dynaudios in a room any smaller than 16x16"

I bought the Contour 1.3mkIIs specifically for and use them in two different 12X12 rooms because of their big sound and diminuitive size. They are a good fit there but ideally you must be able to keep them several feet out from the walls, which could be a problem in some rooms that size.

The McCormick would be perfect for them in most any small to medium sized room.

If they must be closer to the walls, as is the case in one of my rooms I use them in (see my system pics), you can loosely plug the rear port if needed as I do in that room to get a tighter handle on the low end.

MIn my other 12X12 room, they are well out from the walls and I run them with the ports fully open.

I have also tried them in my biggest room, which is ~20X30 foot L shaped. I would want to add a sub to use them in there normally.

Most floorstanders will not fair as well in regards to soundstage and imaging in a smaller room but can work well in larger ones. My Dyns replaced a pair of floorstanding B&W P6s in teh smaller rooms for that reason mainly.

For ultimate flexibility, I like the Dyn monitors alone for most rooms with the option to add a sub as well if needed in a larger room.
