Speakers that mate well with Plinius 9200

Totem speakers and Plinius work very well together and would fall within your budget.

Which Totems would work in a room this size?

forests!

I have seen a few posts that say Dynaudio have a good synergy with Plinius. I can not affort the 3.4 right now, are there any less expensive models that sound good?

There are a pair of Dyn 3.0s for sale now with a matching center channel for $3k that would be a great match. Budget stretcher but actually a good deal on a great speaker.
