This is a great thread with a lot of good construction opinions! I have a question on the Sopra 2: I went to hear them at a dealer where they were set up 3+ feet from the front wall, driving by McIntosh electronics. I loved the soundstage, the sense of height, but the bass (in a certain range) was boomy sounding. I understand that Focal supplies a plug to tailor the low end response. Does anyone have comments on my observations? In my room they could be 3 ft from the front wall.
