I browsed the tannoy website and it looks like they have taken a cross sectional picture of a kef uni-q driver from the blade speaker as a header picture for their ogive phase plug page

Ogive Phase Plug

that must be crazy criminal and stupid

There are also at least three spelling errors in the short text. Maybe KEF decided not to protect their design.

There are more mistakes than just spelling. I cannot imagine why they go to print without a little editing/proofreading.
I am now turning a blind eye to the casual laziness, as I am guilty as charged at times.

I donít see it. I see a driver with a common magnet and ring radiator tweeter firing through a bullet phase plug.

(Wait, nvm. HEADER picture. Yeah thatís crazy. Their driver is quite different from KEFís though.)

don't get caught up in a photo error as it would seem to be. This technology is most impressive and as I have found improves as the driver size get smaller (from 8" to 6" to 4"). The Revolution series XT Mini is said to be a 4" driver but cross diaphragm cone diametre is 3.25". This speaker is the king of the XT series with the most impressive focus stage and image due to its small woofer cone size along with a smaller compression driver diaphragm 0.75". They take several months to burn in and shine but when done they do not disappoint. Bass weight and depth is impressive for such a tiny loudspeaker. The XT Mini is not unlike the ProAc Super Tablette in it's magical ability to convince the listener that they are not missing any bass and that they do not require a sub. As Tannoy has said these are the most technically advanced and best performing DC design in the companies history. Stand and speaker to stand interface are critical in extracting the most these impressive loudspeakers can provide. I am now using the latest four post stands designed and manufactured by Skylan Stands of Calgary Alberta.

The behringer-group bought tannoy a couple of years ago, and behringer as a company do feels a bit cheap. If they can steal or copy others work i guess they easily can steal a picture without blinking

Tannoy's tulip waveguide looked remarkably similar to JBLs which came out around the same time back in the early '90s.

I have no idea which hit the market first.

The KEF and Tannoy phase plugs are similar to the design concept used in the 1970's Motorola/CTS piezo tweeters, nothing too "brand new" in either..
