Peerless 830878 3-1/2" Passive Radiator
If I wanted to use this with two Fountek FE83's in a small enclosure, how would I calculate the volume needed for the enclosure? Do I use the suggested sealed or ported volume x2 for the FE83? Do I need one or two of them? Thank you for your help.
The problem with using this passive radiator is that you cannot tune it high enough to work well. I would recommend simply porting the enclosure which will tune to a more reasonable frequency. With two of these drivers in 0.17 cubic feet with a 1-1/2" diameter, 2-1/4" long port you will have a tuning frequency of about 78 Hz.

Recommended net volume for best frequency response with Tang Band W3-881SJF. What f3 would it reach?
Recommended with a 0.05Ft3 with a F3 of 97Hz.

As per your suggestion, I purchased the Dayton ND91-4's with the 0.04 knockdown cabinets. Might I ask what would be the best arrangement for the radiator with respect to the main driver in each cabinet?

If I were to use a single one of these in each of the two 0.04 bookshelf knockdowns, could you recommend a good 3-4 inch speaker? Likely will use a lepai 2020. Thanks!
I would recommend the Dayton ND91-4 for this application. In that enclosure with that passive, it will have a tuning frequency of about 60 Hz.

I would like to use one of these in a small enclosure using 2 Tectonic Elements TEBM65C20F-8 3-1/2" BMR Full-Range Speaker 8 Ohm drivers. Would this passive radiator help give me more bass in this application?

hi, i want to make a portable BT speaker using a TA2024 amplifier and a pair of Tang Band W2-800SL 2 "I want to make it as small as possible, the idea will be in 4" x4 "x10" my question is: if I use this passive radiator would need to place a subwoofer?
I would not recommend using that passive radiator with a pair of those drivers. They are not designed to product much below about 150 Hz, but they will work in a smaller volume than you have planned. If you port them in that volume with two 1-1/2" ports that are 1-1/2" long each you will have a tuning frequency of about 160 Hz.
