Hi Guy's , I have recently bought a set of 15'' Carvin LS Series Speakers and I am needing to change the Top hat in them so that it will be better to take them off the stands , They are getting stuck on the stand due to the grooves inside the Top Hat mount on the speakers . I bought a pair of metal ones and put them on and they were wobbly, so i took them off and I was wondering if i got some different maybe deeper ones will they work better , But my main concern is it touching the back of the speaker? The ones i have are 3 1/4 inches and i am possibly looking at getting the 5 inch. What do you guys think will it help without any problems?
