Not sure how clear this is really. I was wondering about "EBA2", it being thought to be timing by each driver so I checked Bob's comments at CEDIA 2013, he said EBA "realigns all the frequencies", "low notes high notes and mid notes". So I'm wondering what EBA2 is (and not expecting to be told). It is very effective on my set up for my ears, so -happy (happier with a full roll out though).
