I already have a bunch of the wrong size from Madisound.....The folks in Dallas want pictures of the ones I don't have....You would think that as easy as they break that the folks in Dallas would know what I'm talking about....Of the five pairs of Proac's I have they are all the same......One of the guys wanted me to use the "Velcro".....I already have some Wilson's with the "Velcro" and they won't stay on either.....All I need is the simple plastic Proac device and I'd be home free.........Thanks
