Peerless 830987 3" Full Range Woofer
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.

can i put two of these inside 7(W)x4(H)x3(D), sealed? Otherwise what is the closest dimension to it? Or if a passive radiator assisted is used, wat wud be recommended, the enclosure dimension and PR mass and size.
Assuming those are internal dimensions, sealed will provide an F3 of about 100 Hz. Adding a passive will not change anything, the Peerless passive we offer in the same volume will tune the box to about 99 Hz.

smallest size ported or sealed box
hey now.whats the reccommended volume for 5 of these drivers
I would not recommend 5 drivers as there would only be two ways of wiring them, all in series or all in parallel. Four would be better, a sealed enclosure for four would be .4 cubic feet. Vented is not recommended.
