Dayton Audio SD315-PR 12" Passive Radiator
Two questions here: Can I use two of these 12" PRs with 2X 8" subs RSS210HO-8 in parallel in a 0.75 cf knockdown, like the Dayton Audio TW-0.75MA 0.75 ft³? Or do I need to double the cabinet size for the 2X 8" drivers, even with the PRs?
It looks like the larger cabinet would be the better overall alignment, but both can work. In 1.5 cubic feet you would add 200 grams of mass which will give a F3 of 34 hz. In the .75 cubic foot box you would add 400 grams of mass to each radiator and it would have an f3 of 45Hz.

I have a old Sony cabinet that the total volume is 1.3542cft, will the Series II and this radiator do well together? The measurements are 13x36x8 inches

Is polyfil a standard speaker/sub cabinet build requirement or just to tune as necessary?
It is not required but it is recommended. We do recommend tuning to your liking.

Plan on const sealed 0.8 cu ft box > KFC-XW1200F 350 watt sub. Xmax 8.5 mm Qms 2.897 Qts 0.544 Vas 2.214 cu ft. Box internals: 19.75" x 14.25" x 4.875" Like to get freq resp down to mid 20's. Reconfig to ported or PR(offset back to back)?. Viable?
Unfortunately this woofer is not very well suited for use with a passive radiator or a vented design. If you can afford the space, 4 cubic feet is recommended which would negate the need for a passive anyway - although it will reach into the 20's. This does like a sealed enclosure or about 1 cubic foot.

I'm looking for a PR to use with a Peerless XLS 12". Will this PR work with 3-500 watt plate amp in a 1.5ft box. Will 2 be needed?
Two would be recommended with 200 grams added to each. This will provide a tuning frequency of about 30 Hz.

I just have two W8-740P for my Toyota extracab truck. I want these (2) PR's to extend lower frequency response, not SPL. 100 or 500 watts per sub. What box size for 20 hz response, please. Thanks
Unfortunately you won't be able to reach 20 Hz with reasonable output using this driver. A pair of those passives would require 200 grams of weight each just to reach a tuning frequency of ~48 Hz. This is about the lowest tuning frequency possible, even using a smaller PR.
