Well, my intent was not to trap bass, but to break up the echo situation which was out of hand. The boxes actually do that "perfectly". The only bass "trapping" I've done was to use the subwoofer's room gain controls, which thankfully were effective. By reducing the echo situation it also cleaned up the sharp treble distortion particularly on voices. So, it gave me time to work on more serious and attractive solutions (not to mention the rest of the house). I've only just recently finally stuck those rear speakers on top of the boxes to temporarily (repeat temporarily) get some rear surround, but we haven't played a movie yet to see how that works. I haven't decided if I will use those E1's in the rear or put back the larger and heavier Vandersteen rears, which require more work to install - I'd prefer to do these - save the E1's for possible other duty.
The only effect from the boxes that I didn't like was when I had a short stack on the left and right side walls as well. It seemed to deaden the sound too much. It's possible that it was also a more accurate representation, by reducing echo even further, but I will deal with that later. First, I will install back absorption (?) panels. Probably bass-traps in the upper back corners, and absorption panels on the back wall; we'll see after that. I suspect I will want to have at least a little bit of absorption on the side walls, just not whole hog ;-)
Just so you know.....
Using empty cardboard boxes as "architectural placeholders" is just fine...
But an open empty box is not at all like a bass trap...
In fact, it's more like an organ pipe,or a resonating chamber, and will tend to both ring and vibrate...
Those boxes will definitely color the sound in new, and interesting, but unpredictable, ways.
