Dayton Audio SD315-PR 12" Passive Radiator
what are the purpose of 12 inch passive radiators in stereo speakers or home audio systems.
A passive radiator performs the same task as a port. They are generally used when a port is too large or too long to fit into a small cabinet.

''Hi Guys at Dayton'' I was told that my 12 inch radiators need to be replaced,one in each of my speakers.and was wondering what was the purpose of the passive radiators, my knowledge of speakers is next to none but enjoy the sound they produce very much.
The passive radiator behaves like a large port in a vented box, except substituting the mass of air in the port with a moving mechanical mass connected to a cone diaphragm. These passive radiators can be used as replacements, but will require careful tuning to emulate the characteristics of the original passive radiators. Do some research online for "tuning a passive radiator" for instructions on how to tune a passive radiator (achieved by adding or removing mass from the diaphragm). You won't be able to decrease the mass of these passive radiators below the amount of mass attached at the factory, but you can increase it to get the tuning frequency you need.

What would the ideal setup using a Titanic 12' sub and a 250W Dayton sub plate? Thanks
This passive, even if two are used would not be an ideal choice for the Titanic woofer. They will not have the excursion capabilities at lower frequencies to keep up. I would recommend simply keeping the box sealed, around 1-1.5 cubic feet with that amplifier for the best results.

I am looking at purchasing a set of Klipsch KG 4's that have rear, 12" passive radiators. Both PR's have seen better days, with one of them actually having a hole in it. Is there any reason or concern I may have about using this DA SD315-PR?
Without knowing the moving mass of the original passive radiator I cannot say what differences there will be using one of these. If you can get that information from Klipsch you should be able to add weight to these to match, and the results shouldn't be any different than the factory PR's.

I have Stereo Integrity HT15 D4. Box will be 3~4 ft^3 sealed. Two of these will work? Tuning would be around 20Hz.
I would not recommend these passives with that subwoofer, they will not have anywhere near the excursion required. We might be able to run a model with the TC Sounds passives we offer to see which would be the best option. Please email our tech support with the woofer parameters so we can help you, firstname.lastname@example.org.

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.
