Low voltage interior - multiple transformers single circuit

I am looking to install 6 low voltage light fixtures with 9w mr16 LEDs (sorra) on the perimeter of a 22x20 room. Half of the lights are on one side and the other 20 across on the opposite wall. If I use small inexpensive electronic transformers I need to place it close to the lights. So I need a transformer on each wall. Can I feed both transformers from a single dimmer switch with line voltage?

or do I have to get a large magnetic transformer and just deal with the voltage drop?

You can feed those lights with 1, 2 or 6 drivers. The driver just needs to be sized to the load.
A driver is an electronic power supply versus an actual transformer.
If you use two...... they should be rated at least 50 watts each and you can connect them to the same LED type dimmer.

If you run one transformer I would split the output line right at the transformer and run one line down each side of the room, as opposed to one wire looping around the room. That will reduce the voltage drop along the wire's length so all the lights will be about the same brightness.
