Not really, since the power rating of the 4-layer version is the same, and sensitivity is lower. The 2-layer version delivers more SPL per watt input.
An other thing is that Xmax of the driver is reached with less power input in open baffle compared to closed box or vented box.
T/S parameters and measurements of both can be seen at SEAS homepage http://www.seas.no/index.php?option=com_content&view=article&id=238&Itemid=223
The RO4Y has 173 vs ROY 103g moving mass. It mus be in the coil. Surround compliance is halved in the RO4Y obviously to compensate for this.
