«  Does the job ... It's as foam. »

Six months of use, the foam holds up well, we do not find driving after the weight of the speaker, which is a good point, the foam is rigid enough. Like many competitors offers, the foam is pre-cut if you want to tilt the enclosure itself. I do not teseté 30000 different foams, but compared to the colsound example, it works (maybe with time the foam will deteriorate ... we'll see!)
