I was impressed with the Alta Adam speaker. There were at least two rooms with them, in which one had a black finish to them and another with woodgrain. In the case of the woodgrain pair, I couldn't believe the amount of bass they created. Nice mid and top end too. Of course I don't know what they were driven with. I took tons of pictures and a dozen or so short videos with my Galaxy phone. I will have to go through them eventually to relive the experiences. I'd be interested to learn what the 4lk speakers you are referring to with the large woofer and horn.
Axpona 2022 what impressed you?
I'll start. The Borrensen 01 playing Otis Taylor 'Resurrection blues' was stunning! I also enjoyed the Legacy Aeris on the first floor playing Nils lofgren 'Keith don't go'. In the smaller rooms there was a $4k pair of speakers with what looked like 18" woofers and a horn tweeter that performed well. While the kef ref 3 sounded harsh the ref 5 in a similar small room sounded great just reminding me how much incremental set up affects the demo. I only had a few hours on saturday and missed many rooms due to crowds and would enjoy hearing others impressions from the show.
