I'll bet if you measure the frequency pass through (with REW, yet) you will find that the frequencies muffled are higher than those you would be trying to "catch" with a bass trap. So all is O.K.
People probably need so called acoustical transparency for mid and high frequencies only, and not then if the only purpose is to absorb (rather than attenuating a bass peak).
On the general concept of acoustical transparency, my dealer got off a good one: "Saying 'acoustically transparent' is like saying 'clean coal.' " That being said, I do have an 'acoustically transparent' front projection screen by Semour that probably comes close. I haven't measured it with instruments, just ears. Also Audyssey easily compensated for it, IMO. Only the center channel is behind the screen, and the one part of the curve in which the response of the Center, RF & LF is virtually identical is above about 8K, all the way up.
