Dayton Audio SD270-PR 10" Passive Radiator
I want to build a little 3 speaker system for my patio and I was thinking of using a SD215A in a 1.25ft3 box with a 120 watt plate amp. could I use a SD 270 passive for this or should I use a 12" or should I just port it?
In that volume I would recommend simply porting the enclosure. A 2-1/2" diameter, 8-1/2" long port will tune the box to 32 Hz.

Regarding the 1.5 cu. ft. Box with 2 w8-740p drivers and 4 of the pr's, do I need to stuff the boxes for best results and if so how much would you suggest?
We recommend a half pound of stuffing per cubic foot of airspace to start. There will be very little difference with stuffing amounts in this application.

Would like to build a 1.5 cu. ft. Box with 2 tang band w8-740p drivers and 4 of theses 10" pr's would this work for a car audio sub and if so how much weight would I need to add for proper tuning?
This design should work well. I would recommend adding 100 grams to each passive which will tune the enclosure to about 38 Hz.

Would this work with an Infinity Ref 1060w in about .9 cu/ft sealed on 200 watts rms?

What is the maximin amout of weight (in grams) that can safely be added to this passive radiator?
We recommend no more than double the Mms for these passives.

Will this work with the DS-270? If so, what is the recommended box volume?
Yes these will work well together. I would recommend 2 cubic feet with no weight added to the passive, for a tuning frequency of 32 Hz and an F3 of 40 Hz.
