DCM Time WIndow Identification Help

Hello - I just purchased a used pair of DCM Time Window speakers, but I’m having a heckuva time finding which model they are. They have the traditional TW cabinet design, but the top "rounded" portion is actually made from a series of angled polygon straight edges - see pics. 36 inches tall, 12.5 inches wide. Owner said he’d purchased them new in 1994. Any help would be appreciated. They sound terrific, by the way. He had the woofers re-edged a few years back.https://imgpile.com/p/ygHgoRw#2QoBFEOhttps://imgpile.com/p/ygHgoRw#fLTddCl
