Can anyone tell me about the celestion G12K-100 and the G12T-100 speakers? There in the general speaker section of the celestion website and im interested in what they sound like as im planning on buying up a few old marshall cabs reinforcing the insides as they should of already been, tacking of that plastic outside and sanding and staining the wood and replacing the speakers to get something unique. These speakers are cheaper then the classic series celestions and i wanna know if there good or as cheap sounding as their price tags?
