Yeah, the biggest difference is the lower usable response of the 2234H versus the higher power capacity and sensitivity of the 2225H. I highly doubt you could hear the difference in the group delay characteristics.

The graphs show each transducer in what Bass Box 6 Pro deems as their maximally flat alignments. Swapping tranducers in a given volume is where everything changes e.g. both transducers in a 5.0 cubic foot volume.
