Dayton Audio SD215-PR 8" Passive Radiator
Would just one of these 8" passive radiators work paired with a JL-Audio 6W3v3? Or would it require 2? In such a scenario, minimum sealed box volume would be? Would weight need to be added to the PR? How is weight typically added?
This will work with one passive. I would recommend a volume of 0.32 cubic feet with 75 grams added to the passive which will tune to 37 Hz and provide an F3 of 37 Hz.

To eliminate port noise on my Energy ESW-8 8-inch powered subwoofer, I'm looking to seal up the reflex port and add one (or two) of these PRs. The sub goes down to about 33-hz. Would this passive radiator fit the bill for what I need?
It could, unfortunately we have no way of modeling anything to help with tuning or how much weight to add. If the active woofer is 8", I would recommend two 8" passives. Adding weight will drop the tuning frequency but you don't want to add more than 75 grams to each of these.

Can you use an 8 inch passive Radiator, with an 15 inch woofer, 6.25 cubic ft. cabinet? it was calling for 2 four inch ports 1 inch long, Can I use the passive instead?

Would this PR be a good fit for the Dayton SD215A-88 8" sub in a .35 cu ft box? Or would I be better off leaving the subs sealed? This would be under each front seat in my car for midbass. Transient response is slightly more important than volume
Yes, that passive radiator will work well with the SD215A-88 in a .35Ft3.

Im building a set of Line-Arrays 7"x72"x 11" internal , with 8- SB Acoustics 5" - SB13PFC25-08 . I was thinking of using 2 x 8" radiators one on each side at the bottom of the case ,is my assumption correct on size of radiator and mounting location ?
You will actually need eight of those passives in order to maintain a high enough tuning frequency and keep excursion down. Eight passives with no weight added would provide a tuning frequency of about 45 Hz and F3 of 70 Hz. In the volume you have you could also just port the enclosure with two 4" diameter, 5" long ports for the same tuning frequency but an F3 around 50 Hz.

Looking to make a small subwoofer for the garage using this with the Tang Band W6-1139SIF 6.5. Is .33 cubic ft. the ideal size and how much weight would i need to add?
Yes that volume is perfect. I would add 75 grams to the passive which will provide a tuning frequency of 35 Hz and an F3 of 44 Hz.
