Which speakers will fill 5,000 cubic ft coherently

To take a step back for a second, you're more likely to have success if you first match the speakers to the room and then match an amplifier to the speakers. You seem to be trying to collapse these two separate steps into one. Not that it can't be done, but it greatly limits your options. In other words, why are you so tied to your amp?

If the emphasis is on coherent sound you might also consider the larger coaxial designs from Altec (Great Plains Audio), the big classic styled Tannoys or the various Phy based speakers. They are all very efficient and like tubes.

Can anybody tell me why there are such divided camps on the Definition?

It's no different than any other speaker or component. Some people like the sound, and other people don't.

Audition them in your home and you decide.

1. They weigh 250 lbs together
2. I built a special 7 ft coffin with hinges to accomodate them
3. They are the best amplifiers I ever heard
4. They are the most reliable piece of equipment I own, despite the 58 tubes
5. The task is not so impossible - to find an 8 ohm speaker is not so hard

You don't need the speltz if you use the new 30 ohm Zu def 2 speakers...

Get somebody to take a digital photo or two and post your system with the photos on agon under member systems. Given your limitation of 18" in your large room, you may have a setup issue that could benefit from some helpful agon member comments before you can make any convincing loudspeaker assessment.
