Hi Claude
Well one can make an argument for putting any bass speaker close to a wall.
If you measure a speaker what is off the ground with a mic off the ground, you see a big notch in the bass response because there are two paths to the microphone, that are different lengths.
When that difference is equal to 180 degrees, you get a cancellation notch.
The same is true for a bass speaker near a rear wall except now when the speaker is 1/4 wavelength from the wall, the reflection returns 180 degrees behind and now is partially canceling the front radiation.
For a bass speaker a safe thumb rule for no cancellation would be put it 1/8 wavelength or less from the wall (s) at the highest frequency in question.
The Tapped horns are no different in that regard, just low pass and eq them flat in room.
Hey i got to hear 12 X DTS10 tapped horns this last week and weekend and with a large "live band" which was pretty cool.
In fact they are taking them on tour. Jason from the shop was in the mix booth and took a video, if you have headphones or good speakers you can hear the very low bass.
