Threshold for 4ft wide sealed door suggestions needed

I'm finally adding sealed door to my HT, pick-up the door tomorrow

6 foot opening being re-framed for 4 foot wide door rough exterior dims 50.56", I'll round up to 50.75"




Now, I've got the riser re-do and framing figured out, but not sure the material for the threshold for 4ft wide sealed door, hence I'm asking for suggestions.
I used 2 x 6 construction, and the door jamb is 6 9/16" wide to account for drywall.
I'll be getting the auto bottom door seal.


Stone or marble or? I don't want to sink $$ here, just a nice flat surface for sealing.

You could use a thick piece of hardwood, stained and covered with poly.
You could go to a counter top shop and ask about a remnant piece of stone, be aware that it will be prone to cracking until it is firmly secured and supported. They make pieces that size all the time for backsplashes.

You could get a specific acoustical door threshold, e.g. Pemko 2008 STCx380. That will further improve sealing.

Thx Jeff and Nyal;
In my zeal to get going on this I cut the carpet too wide!
Usually one hangs the door and then the flooring material is put on....

Cut is 5 1/2" wide, should have only cut for the wall side that width for the green board, and 3" as placeholder for under the door threshold, what's out there commercial wise gets $$ at 7" width, $125 for 49" length. http://www.tmsoundproofing.com/Utili...us-Widths.html


Before cutting:


I actually like the hardwood approach Jeff, desire is a lighter colored hardwood as I use pine for all my baseboard and trim.
I can do that and it will even hold down the carpet edges w/o looking outta place vs aluminum, I'll step cut the backside so it mounts flush to the cement in between the carpet them clamps down on the carpet edge with 1/2" or so overhang.

Nyal;
I'm looking at this 3 side perimeter seals and bottom seal, via http://www.tmsoundproofing.com/Door-...f-Gaskets.html
About $145.62 for Door Gasket - Basic Neoprene seals and about $91.02 for Heavy Duty Automatic Door Bottom
