Media reviews

One15 and One18 with Amp100

“If you demo a set in your room, it’s very likely you’ll keep them.”

“These monitors perform well above their price range and are an incredible value for such refined tools, arguably one of the most critical tools for mixing. The mixes I complete on them are translating well to other rooms and playback systems, and I’m producing the best work of my career.”
