Yes, I did the measurement thing years ago out of curiosity, and I also had an Audio Control auto EQ unit at one point. These days, I have no interest and just trust my ears.
I can add that increasing treble levels on Walsh 5s using the on-board adjustments do make the sound a tad more forward than otherwise based on my experience listening with different levels set on the Walsh 5 drivers.
A Walsh that sounds forward is probably having somewhat more of the overall sound being produced by the super tweeter rather than the Walsh driver, which, like most omnis I believe, is naturally laid back as a result of more sound being emitted towards the rear than most box designs.
