TS-W126C Measurements..
 

I need to get my hands on some measurements of this Premier 12".
Ive been looking for a while and cant find the exact measurements of the diameter, mounting lip/depth w/ rubber gasket. Im going to be flush mounting this in a fiberglass enclosure and want it as tight and flush as possible. Response Appreciated ~

The manual says 278 mm or 10-7/8" for the cutout hole with a 157 mm or 6-1/8" mounting depth. For the outer edge and lip thickness, you may want to measure by hand. That should be easy to measure on the actual sub itself. Plus, manufacturing tolerances may mean that your sub is actually a mm or two different from the spec. You want to measure the actual sub you will be fitting.

Hmmm... let's do some more math. They spec the dimensions as 13" x 7" with a 6-1/4" mounting depth on http://www.pioneerelectronics.com/pna/premier/product/specs/0,,2076_58531033_153020670,00.html. We can thus calculate that the lip thickness will be approx 7" - 6-1/4" = 3/4". If we go with the manual's specced mounting depth, 7" - 6-1/8" = 7/8".

Appreciate all the research , but i've found all that info. I only need the exact diameter. I'll be sinking the mounting ring an 1 1/4' into the enclosure for excursion clearence for my flush mounted billet grill. And im building the molded enclosures now, get them over with. So its only the diameter I need :)
