Peerless 830878 3-1/2" Passive Radiator
How would the addition of 2 of the above passive radiators affect (tuning, resonance, etc.) with a Peerless 3" 830987 in a sealed .05 cubic feet enclosure? Thanks again.
Would this be a good consideration to go with a pair of Tectonic Elements TEBM65C20F-8 3-1/2" BMR drivers? Either single 15"x5"x9" (approx) enclosure, or dual 8"x5"x7" (1 radiator in each). Also considering HiVi B3M drivers. Sizes are flexible.
This passive radiator will probably have enough available displacement to work well with both of your drivers but it's usually a good idea for the passive radiator to supply 2 times the volume displacement (Sd * Xmax/10 = Vd in cm^3) of all the active drivers working in the same volume, so you'll need to calculate that out, and you might need to use dual passive radiators instead of a single one. If you use dual passive radiators, it may be a good idea to put them on opposite sides of the box to reduce cabinet vibration from the movement of the passive radiators.

A Peerless 3" 830987 full range driver in a .08 cubic feet sealed enclosure... how would the addition of this passive radiator to said speaker affect it (tuning, resonance, etc.)? How would the addition of 2 of this passive radiator affect it? Thank you.
Adding a passive to this system will cause a drop in F3, from ~120 Hz sealed, to about 85 Hz with the passive. Two will be too much and drop the tuning too low to be practical, but a single passive would work relatively well.

Hi, Will this passive radiator would work well with 2 Visaton BF45 speakers ? http://www.parts-express.com/visaton-bf45-4-ohm-18-full-range-speaker-4-ohm--292-612 Will it be possible to have good under 100hz bass with this ?
This will not be a good match up, the Peerless passive will create a tuning frequency far too low for the Visaton. Usable bass response from this driver is not going to be very possible with an Fs around 150 Hz and limited Xmax.

I was wondering if this would work well with 4 tymphany PMT 40N25AL0 https://www.parts-express.com/tymphany-pmt-series-40n25al01-1-1-2-aluminum-dome-micro-full-range-speaker-4-ohm--264-1154 I am making a small bluetooth speaker setup. Thanks
That passive will not be a good choice for those drivers, it will provide a tuning frequency far too low to be practical. I would recommend a standard vented box for these. A volume of 0.06 cubic feet with a single 1.5" diameter, 1" long port will tune the box to about 200 Hz.

Will these work well with the AuraSound NS3-193-8A? If so, what configuration would you recommend?
Theoretically it will work, but the tuning frequency will be too low to get useful output below about 100 Hz. You would be better off porting the enclosure with a 1" diameter, 5" long port for a tuning frequency of about 60 Hz.
