My thoughts precisely. There is a little bit of foam in the back chamber and I think the manufacturer does everything reasonable to mitigate back wave reflection. To go the extra mile and if room allows I think a long tapered tube would virtually eliminate the back wave. And as a bonus the FS of the driver would be reduced. Just the same as putting a woofer in a small sealed box raises the system FS, by increasing the back chamber volume and venting it, I think the inverse would happen, a reducing of the FS. Question being, would this allow more usable low frequency output from the compression driver. Well, that would be an interesting experiment. A quick test on my DATS system and observing the phase plot would reveal this pretty quickly.
