Took these out for their maiden voyage last night for Real Estate (indie rock band).
Small club, pretty standard volume for that kind of show, I suppose - not crazy loud or quiet. I checked my watch during the opener and it was in the mid 90's for dbs. I'd guess it was between 90-100db for the most part. Will post a link to the archive once I've edited.
I thought the ambeo performed really well. On par with my DPA > Dvice setup? Probably not...but way more than serviceable. I mean, we're getting into subjective territory - so all I can say is that for the bulk of the shows I do, I think these will do just fine.
Also recorded with a share MV88...I'd say the results are comparable, fwiw.
