Seeking Information for Optimizing Sound Quality: Audio Art 12 RW Subwoofer

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.

That's a hard one to search for. I wish they used some less common words other than "art" and "audio" and "reference".

Do you have access to something like a Dayton Audio DATS? That can measure your woofer and give you all the numbers you need. If you're electronically savvy, you can do some DIY stuff to measure the numbers without a DATS also.

I don't have access to anything that can perform these measurements.

I Just Found found these images in a WhatsApp group.
