Mid-Horn...EV Manifold technology

Someone's offering me a pair of un-assembled Mid-Horns with the fixtures that go on to Electro-Voice's Manifold technology mid-box. The stuff has been designed to be used with a ten inch driver - EV uses their own DL10X mid-bass driver. I want to use this as part of a flying system in outdoor PA.

Has anyone heard the Manifold technology mids? If yes, opinions on different aspects of the sound, ie., midrange purity, breath, tonality etc.,

(Presently I use a straight horn for the mids with a twelve inch driver. Coupled to this is a folded horn with 18" EV drivers for the bass and Horn Loaded Highs.)

Thanks in advance.
