"How would these compare to DecWare ERR Radials? Are there other similar designs out there?"
Have not heard the DECWares to compare but from what I read, the design seems closest to some of the smaller OHM Walsh CLS perhaps as anything I have seen. They do not mention using Walsh technology or applying a wave bending approach, but the driver configuration appears similar to OHM CLS/Walsh. The OHMs appear to be designed by default (custom mods can be requested) to work better closer to walls perhaps.
