I don't see any mention of freespace specifically shown on the spec sheet, but I suppose you may be right. I would have expected halfspace, but the chart and other specs may reflect freespace measurements.

All the data we gathered at the Prosound Shootouts were done with ground plane measurements. In 2006 we did all speakers at a constant voltage. In 2005 and 2007 we did all speakers at 28.3v, 100w, 200w, 400w and so on.
