I will check it out, I guess it is not widely done in normal HTR's due to the low feedback on the thread. Thanks again..........
No, this is a special application and you need lots of space behind the driver/s.
Not sure if you closet would be large enough. The door would have to be replaced and solid, no movement what so ever.
Some folks use attic space, others crawl space or basement, like Tom Nousaine, with a plenum to the upstairs. And, if the space is exposed to the outside, like an attic or vented crawl space, you better check the neighbors.
