ICT technology

Are there any manufacturers using this technology.? I remember a review of these speakers, which was pretty positive.

Hi. I had a set of these Tannoys and only sold them recently. Not sure if same technology but certainly had a nice midrange and top end. Bass was a bit asthmatic as mentioned by the op on linked thread. The dual concentric drivers are good and lasted well (more than 20 years) but the box quality could have been better. Mine were ok. tannoy 611 mk2
