I'm interested to know how the original Miras perform at low to mid volume levels and what the minimum distance they need from rear and side walls as I have only heard a pair in a large room with Ayon mono amps. Can anyone give me an idea of what they would consider a minimum room size that they are likely to work in. Controlled bass is a big criteria for me. I would be using an Aesthetix Calypso Sig pre and Atlas power amp.
