Anyone heard Zu Druid speakers?

A couple of questions regarding the Definitions.

1. On Audio Circle a question arose regarding "limited dispersion", which would negatively impact the size of the sweet spot. Does your experience align with the comments of 213Cobra?

2. How can the Defintion be time aligned and phase coherent when the 4 bass speakers are rear firing? I'm not sure I understand how the low frequency sound waves could reach the listeners ears at the same time as the midrange and tweeter when the wave is traveling in the opposite direction.

Thanks for any clarity on these issues.

Ton1313, thanks for your response. They sound very intriguing to say the least.

213 cobra... Sarajan believes if you purchase the Druids with a Zu sub, one would have 90% of the Definitions performance cababilities. Would you agree with his statement? This combination (Druid + sub) sounds like a winner to me.
