there's a huge difference in sound. In fact ... the air's do not sound anywhere near the BM15A's and I've allways thought that Dynaudio should have concentrated more on the way they sounded then on all the features. It's almost as if at some point, after programming the features in those things someone woke up and said 'hey wait a minute, we have to make 'em produce sound too ... '
AIR's ... don't like them. They're a puffed up features with twists and bells marketing thing.
The BM15A's ... love 'em.
At some point TC offered us to replace my 5.1 set with Air's. And it was a pretty good deal on paper too ... in fact ... one that wouldn't have cost a penny.
The Air's are not the only 'mistake' that dynaudio made over the last year imho.
They put some dfegad dude in charge of TC and Dynaudio benelux sales that thinks he invented the wheel if you know what I mean. The very well sales technique trained dude that doesn't know the difference between a box of washing powder for your dishwasher and a speaker.
Sad ...
Anyhow ... back to the topic ... I actually think the genelec 80** series could be placed next to the BM15's ... No the same sound ... but definately similar things I like in them.
