Dayton Audio SD270-PR 10" Passive Radiator
The active woofer is on the front of the cabinet - can the PR be on the bottom facing down? Or does that eventually cause suspension/spyder issues?
This passive will work fine down firing.

Is there a cheap(under $50) 8" or 10" subwoofer/woofer that'll work with this p.r. to get me into the low 30s in a 2.5 cu. ft. box?

I have two of these PRs, a Yung SD500 (no boost) and a Dayton TIT280C-4 10" Mk III subwoofer. Will these play well together? If so, please recommend enclosure volume and weight to add to each PR for F3 about 25-30 hz. If not, what would be best? Thanks!
Unfortunately these will not work well together. The passives will not handle enough weight for that low a tuning frequency and also do not have the excursion capability to keep up with the woofer. We actually do not have a passive radiator that will be a good match, so a standard sealed design would be the best option.

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.
