I have found 30ppi renticulated foam in an online aquarium shop and ordered it. It's specs is the same with what Geddes used as plugs in his horns. I will try that on my cf1400hz le cleach with varying depth through layering. First just a thin layer at the throat, then some more and then 70% of the horn covered like Geddes suggests. I will try and note the differences and will try to measure its effects. It seems it will be very hard to measure as they are quite ineffective sound pressure wise (transparent dynamically?), but have an effect on tonality...
