I was looking for speakers for a month. Having rented and played with the Yamaha Dxr-15 mkll twice, every speaker I went to listen to seemed very little compared to the Yamahas for my ears and what I want. I had heard almost all the well-known brand names. And I happened to listen to these... that was the first shock, the only speaker very close to the Yamahas. And so I ended up buying them (Rcf Art 915a). I also did my first event with them... the result was incredible. Very loud and deep bass and crystal clear highs no matter how much I turned them up... they have a lot of "power" and the sound quality doesn't deteriorate... I will make another purchase for two more later...
