Dayton Audio SD315-PR 12" Passive Radiator
I have 2 12" subs, going in to my car, I would like to add more bass than Had in my sealed box but want to save as much space as possible. Would one of these give me more boom or two? also how would you recommend mounting them in the box?
Adding a passive radiator will effectively give you a ported response and the ability to tune the enclosure, unfortunately without knowing the model of the subwoofers and size of the box I cannot say whether this will benefit you or not. These mount like any standard subwoofer driver, position in the enclosure makes no difference.

Can I use two of these passive radiators with two Dayton Audio DVC310-88 i have? Do I think of two offices subwoofer with enough resolution and detail, what would be the volume of each box? What would be the "frequency of reinforcement "of them?
Two will work at lover power levels, however anything above 200 watts will cause over excursion. I would also recommend adding 200 grams of weight to each passive and use a volume of 2.9 cubic feet total.

I am thinking of using two of these PRs with either a RSS315HF-4 or a RSS390HO-4 driver. Which driver is more suitable? Also it would be helpful if someone could tell me what the optimal box volume and how much mass must be added to each PR.
Unfortunately these passive radiators will only work in multiples of four due to the displacement of the Reference woofers. If you were to use four passives with the 12" sub, 200 grams on each will tune the box to 28 Hz.

I'm building a pair of towers using Lou C's Kaverna for the top and I would like to use the Dayton DCS205 side mounted on the bottom. Can I use these 12" radiators in place of a 2" x 10" long port tube in .85 cubic feet? Seperate chamber for the sub?
This is a question that you need to ask Lou C directly, He can be contacted on our Tech Talk forum.

Would 2 of these keep up with a JL 12w7? I'm looking at a 6 ft/3 enclosure tuned to 18hz. The JL has some stroke to it though!
Unfortunately no. The only passive this sub will work with is a pair of the TC Sounds VMP 12" models or larger. In a 6 cubic foot box (for one subwoofer I'm assuming), there is no reason to simply port the box and get the same tuning frequency, saving money on passives. With a 5" diameter port that is 20" long, you will have the same tuning frequency.

Will this work with Peerless 10" XLS?
Also, do I need one or two?
In .75 cubic feet I would recommend one of these passives with 200 grams added to it. This will tune the enclosure to about 28 Hz.
