I purchased the Icon 12s last summer. I have been very happy with them. The standout feature for me is their relaxed, smooth sound. There is no loss of detail with this sound signature. All the usual audiophile attributes are present (imaging, soundstage, etc.) They play loud when in the mood (100+ dB) with no change in sonic character.
They replaced Perlisten S7ts which are excellent speakers. I wanted to try a horn speaker with a big bass driver. These fit the bill. The horn has never called attention to itself, always smooth and well integrated.
Driving them with a Hegel H30, PRIMARE Pre35, Hegel HD30 DAC, and HIFI Rose RS130 streamer.
