Words of the press


Dice la stampa - Article

If you're into 'real' music like they play in your downtown clubs [...], the Big Fun 20 is perfect to get down and dirty with, not nasty and tiresome.
It's a big friendly sound that goes loud without pain and seems tailor-made for Rockers young and old.
It's about live sound eight to ten meters from the stage. Just because most audiophiles no longer reference reality does not mean Blumenhofer got it wrong.
