I believe they were just a pair that were hanging around, they don’t appear to be very sturdy.

The 8Cs were at the ‘Cranage’ audio show in the u`k this last weekend,
Quote courtesy of ASR forum.

‘I spent quite a bit of time in the Dutch & Dutch room at Cranage on Sunday and I'm impressed. A bit disappointed that the dealer played so much electronic/dance music which for me made it more difficult to assess the speakers. But when they did finally play some decently recorded vocals I was struck by the clarity and complete lack of smearing. The wide soundstage was very evident (I was sitting slightly to the left of centre with some folks in front to the right, but not blocking the right speaker) and instrument placement was excellent. Bass was powerful and very well controlled. They simply played music with an overall cohesiveness that didn't call attention to the speakers at all. For all their clarity, punch and detail I couldn't see these speakers bringing about any fatigue in long listening sessions. There was nothing else at the show that came close to them...all IMO, of course.’

8Cs ‘Roon ready’ !
This means that a system is just the Roon Core and a pair of 8Cs!

Passive cardioid speakers have actually been around for a long time, I've made some myself-

Not terribly difficult to get it to work, but a lot of work to get it to work *right*.

For me I decided that since the room and the speaker are both my bat and my ball, it's even more effective to do a half dipole (fig8) with the rear lobe being both absorbed and redirected tangentially away from the listening position. Dipole has both less stored energy (cardioid vents still acting like a bass reflex port to some extent) and a tighter pattern. This requires the room, speaker and DSP to be designed as one complete system though (I'll be doing a studio build thread here soon).

8c and Kii are both excellent designs, but it is fair to say that if someone places a high priority on directivity below (typical) Schroeder, Geithan and Kii do that and 8c does not (8c rear subs are typical omni). Personally I don't think directivity below Schroder is useful anyway, but would be open to be proven wrong.

The 8c looks like an oblate spheroid waveguide...I'm a big fan there (using a large format beryllium compression driver on SEOS24 WG's).

It's cool to see Dr. Geddes work make it into more studios. Something that is long overdue.
