Peerless 830878 3-1/2" Passive Radiator
I'm building a small portable speaker with four dayton CE46P-4 1-7/8" Paper Full Range Drivers (Fs = 150 Hz). Would one of these passive radiators help to extend the bass of the 4 full range drivers? Also what would be the min. volume for my enclosure?
The passive will help bring the F3 down to about 115 Hz in 0.084 cubic feet with no weight added.

I am planning to build boxes using 4 Tectonic Elements HIBM65C20F. How many of these would I need, and what size box? Should I step up to a larger passive like an 8 inch? What feq would it be tuned to? and also information using 2 Tectonic BMR's
Four drivers and four passives will work well together in about .8 cubic feet. With no weight added, you will have an F3 of about 70 Hz.

Can I use these to extend/increase low frequency output of a full-range 6x9 in a small, sealed enclosure? Would multiples improve lower frequency response vs. just one, such as to supplement 60-80hz range?
I would not recommend a passive this small to be used with a 6x9. Something like our 8" Dayton would be a better choice although I cannot model the box volume or tuning frequency without driver specs.

How do i tune this passive radiator ?
Weight is to be added to the back of the cone or dustcap by gluing washers or other small weights to it.

Could this be used with two Dayton ND65-4?
I have these two daytons in a .07 cubic box but its a little small for them. I would like to increase the bass output and was hoping this would suit my needs.
If you were to incorporate one passive with two ND65 drivers with no weight added, you will have a tuning frequency of ~50 Hz and an F3 of about 85 Hz. I would not expect too much below 75-80 Hz with a setup like this.

Can I use this with 2 2" full range driver?
Hi,Is it possible to use this PR (one of it) with 2 2" full range drivers?And I assume it's oke in using the same recommended volume for a vented enclosure stated on the drivers specification for my enclosure (see my related product)And mount it on the same wall where the drivers are?Thanks!
You can although you will not benefit from it much if at all. These drivers have a free air resonance of 175 which means they will not be able to reproduce low frequencies anyway, so the passive will not be doing much.
