A friend of mine salvaged this 12" Rola out of a Hammond tone cabinet. <a href="http://s27.photobucket.com/user/irishronin/media/20150113_171347.jpg.html" target="_blank"><img src="http://i27.photobucket.com/albums/c187/irishronin/20150113_171347.jpg" border="0" alt=" photo 20150113_171347.jpg"/></a> I'm considering using it in my Alamo Fury for harmonica. Couple questions... Should I leave the inner cone intact? The mag is pretty beefy looking. Will it handle a 18 to 25W load? Are these inherantly clean, or do they break up at all? Please advise. Thanks.
