Does anybody know what these cabinets are about? Seller says dimensions are 138 x 61,5 x 55 (in cm, h,w,d). Now it is stuffed with a classic bass driver but for those of you not speaking german: Before he bought the loudspeaker it was installed in a theatre with a 605 inside!!!

Hard to believe. But maybe I've got a lack of information. Thanks for any helpful comments.

I?ve been through many theatres here in the U.S. and I have never seen anything like it. I?ve only been in one that used duplexes for mains and those were in utility cabinets. My bet would be that in this case ?manufacturer unknown? means ?home built?. But then again, I have never been to any theaters in Europe so I couldn?t say for sure.
