Other possibities



I've never fooled around with passive radiators either. But since Vas of the LAB12 isn't very high, I expect cabinet size wouldn't be large either. So tuning a system with a single driver might have been problematic using a duct.

Might go with an EBS alignment that uses a larger cabinet, but that would probably put fl down in the single digits or low teens. I'm not sure there would be much energy down there with a 12" driver regardless of its tuning, but I haven't checked either.
