HiVi B3N 3" Aluminum Driver Round Frame
What size port would I need for an enclosure 5.5" wide by 5" deep and 7" tall, inside dimensions. They are on a surround system with a bass speaker. I have some nice oak boards 5.5" wide and 7/16 thick that I want to use.
I would recommend a port that is 1" in diameter and 3" long for a tuning frequency of 72 Hz.

I am making a home made portable bluetooth speaker and I want pure bass. I would like to use 2 of these speakers for portable bluetooth speaker. For 2 of them what is the best box mesurement for bass? How much volts does it take to power one of these?
I would recommend a total volume of 0.25 cubic feet with two 1" diameter, 2" long ports for a tuning frequency of 77 Hz. Speakers aren't rated by voltage, they are rated by wattage. Any amp that can provide 10-15 watts of clean power to each of these will be plenty.

can some give me a slim box design in In. for 2 of these for an Fs of roughly 40Hzexample 20"T x 5"W x 3"D
This driver requires about 0.25 cubic feet and has a pretty peaky bottom end. With an enclosure that is 36"Hx5"Wx5"D with a 1" diameter, 2" long port you have an F3 of 44 hz.

An Array Question ...
Id like to use at least 4 per side for midrange duty paired with dual 10' Woofers (rating of 93-94 db) .What would the combined db level of four of these wired series/parallel for a final 8ohm load be?Can I get away with 4 per side or do I need to go to 16 per side to maintain an 8 ohm load and be able to keep up with the woofers.Id wanted to use a Dayton PT2C-8 Planar tweeter (94 db)
Wiring four drivers in series/parallel will be the same as wiring two drivers in parallel. You will gain 6 dB of output, so in this case four will have a sensitivity of about 87 dB. You will need 16 to achieve a matched output to the woofer.

As these speakers are not good up to 20k, what would the appropriate crossover network be to roll them off after about 7khz. I find their performance really drives other speakers down in terms of quality. I will have 3 of these in a 2 channel array for 6 total. Other speakers will be present in the arrays as well and I do not want them to be affected by the crossover. If it is a simple capacitor or something I will just install one in each chain as there are 3 chains per side wired to 2 ohms each.. I am happy to provide more information if necessary regarding the setup.TLDR: Looking for a crossover design to roll these badboys off at around 7khz.
In order to cut off everything above 7k you would need a very small inductor wired in series with all three. Something with a value around .04-.05 mH will be ideal for a first order network. I would recommend adding a capacitor in parallel as well to create a steeper roll off. If you choose to do this, you will need a ~5.1 uF cap and a ~.1 mH coil.
