Tectonic Elements TEBM65C20F-8 3-1/2" BMR Full-Range Speaker 8 Ohm
What would be recommended volume for 4 of these drivers in a line array arrangement? Sealed or ported?
A sealed enclosure would only need to be 0.25 cubic feet for all four with an F3 of 90 Hz. This will provide the smoothest lower mid-bass response. A vented cabinet would need to be 0.9 cubic feet with a 3" diameter, 3.5" long port for a tuning frequency of 62 Hz.

I want to build a line array with 24 drivers per side. What would be the total db sensitivity when wired in parallel/series banks? I forget the how to add db with multiple drivers.
Would like to try long speaker to go under my computer screens with your 3/1/2 passive radiators with 4 of these drivers (2L, 2R drivers (4 ohms) + 1-2 passive radiators per side) - can you recommend a ballpark volume per side? Thanks
For decent results a volume of 0.128 cubic feet per pair with two Peerless passive radiators will have a tuning frequency of about 60 Hz and an F3 of about 80 Hz.

Is a high pass filter recommended with these drivers - What is the suggested freq.? Is there a stock PE part?
A highpass is only recommended if the application calls for it. If these are going to be used at higher volume levels a high pass is recommended. If they are for near field lower level listening you probably wont need one.

Cabinet with internal dimensions of 6"x6"x10" for 360 cu. in. For this I would like to use a port 1/4"x 6". What would be the best port length?
I would recommend a 5" long port for a tuning frequency of 61 Hz.
