There are some reports (from reliable sources) that WT2 may still be the preferred option;

WT-3 testing of 2204, Fs higher in sealed box???

Which brings up another point. Test results are only as good as the gear, the setup procedure, and the interpretation of the results. It's a real treat that DIYers can now get the info they need, but bad info is worse than no info.

For example, TS specs can vary widely depending on the position and securing method (or not) of the driver. Indoor acoustic tests will have all sorts of false data unless the software has "windowing" ability to catch only the direct sound and shut off before any reflected sound arrives, and the user must set the appropriate parameters based on mic placement and distance to reflective surfaces. There's plenty of bad data posted online to prove it. Bottom line, read the book and follow the instructions.
