Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer
Is this a freeair subwoofer
This will work relatively well free air but it will have limited extension below about 50 Hz.

I am a newbie to building speakers but i have a pioneer 12" shallow sub box .5 cu/ft and a 12" dayton passive radiator and was considering using this 5 1/4 " sub driver in that same shallow sub box with the 12 inch passive radiator. possible?
This combination would work relatively well in that volume. I would recommend adding 200 grams to the passive radiator for a tuning frequency of 38 Hz.

I am thinking of using this little sub in a DIY sound bar with 2 Tang Band W4-1337SDF powered by Dayton MCA2250E 2.1 25x2 and 1x50. Questions what is the best direction to fire the sub i.e. forward, down, etc... @ .36' what port length and diameter
The orientation of the woofer won't really make any difference in this case. If you plan on having it crossed above about 150 Hz to the other speakers you might want to front fire it, but any lower and it won't matter. I would recommend a 2" diameter port that is 10" long for a tuning frequency of 45 Hz.

I was thinking about this sub "Tang Band W5-1138SM 5-1/4""in a box w/ an internal vol of 0.318 cubic ft with two passive radiators of the same size one on each side. what amp should i use and will this configuration work?
Our SA70 subwoofer amplifier would be a good match for this woofer and have a decent amount of headroom available.

Would it be possible to use four of these speakers in an isobaically mounted 4th order bandpass box but instead of using ports i could use passive radiators? When i say isobaric 4th order I am refering to the style of the polk C4
Unfortunately we have no way of modeling this type of enclosure using passive radiators instead of port tubes. Based on the model using ports, this is not a practical design using these drivers, as the box volumes are very small and port lengths are astronomical, with two 2.5" ports needing to be over 200" long. A standard vented box would be much better suited for these woofers.

When I model this in various tools the most consistent result for a sealed box is 5-6L F3 was in the low 70s. I'm trying to keep the box small (so sealed) but would like to get another 10hz our of it. Possible? Or do I need to go to vented?
The F3 will only tell you so much when it comes to what you can expect from a driver. Depending on application, I will generally look at the F10 number for a more realistic bottom end when room or cabin gain is applied. With an F3 of 70, you can expect the actual extension to reach the mid 40's.
