Peerless 830987 3" Full Range Woofer
I'm looking to upgrade my 5.1 home system to a 7.2 and was thinking of these for the satellite speakers or the 4" Dayton Audio DS115-8. I will be pairIng with a tweeter, but I want something small that will work well, which would be a better choice?

Do you have - (1) a separate data sheet with on and off axis response curves, (2) Is there a Peerless driver the same size but with different cone material, (3) any with Ferro-fluid, (4) What is essentially the same driver but with a different magnet?
Unfortunately we do not have any other similar size Peerless models with different magnets, cone materials or ferrofluid. You can see a spec sheet for this model below which includes off axis response.www.parts-express.com/pedocs/specs/264-1054-peerless-830987-specifications.pdf

is 54Hz a realistic if tuning frequency for this speaker? It says 54 if in a .22 box with a port...but is that just math numbers or actual realistic tuning number? It's for a desktop application, but would like it sound as nice as possible. TLine?
A tuning frequency that low is not very practical. The lowest I would recommend tuning this driver to would be around 80 Hz, which would require a smaller volume.

So another question I had was I was looking to see how to make a TLine box for this sub and I ended up with a box 7.25 x 5.75 x 9" with a 1.5 x 4.75 port folded over 4 lengths so about 36" of port. Is this going to sound better than just a .22 ported box?
"Better" is a relative term. A TL will have similar extension capabilities as a vented box, but require more volume to get there. If done properly the transients of a TL will be "better" than a vented box (IE less group delay) but at the usable frequencies of this driver, we are only talking milliseconds. For practical purposes a standard vented box would make more sense.

I am putting this in a box with a LP2020+ and a tweeter. Subtracting the volume of the tweeter and amp, the box needs to be .245 if it's ported. Can I use a passive radiator to size the box down in volume, or do I need a make a 1/2"x5x5.5 square port?
Using a port will provide a more practical tuning frequency for this application, the passive radiator will tune too low.
