I owna 12-inch Audio Art Subwoofer, an Old School model. However, I don'tknow much about it. I only know that it's a 12 RW model from theReference line, with a 400W RMS power rating. I would like to build abox focused on sound quality (SQ), but these are the only parametersI have. If anyone has information about the other parameters orpossesses the manual and could provide me with the information, Iwould greatly appreciate it.
