Tang Band W4-1337SDF 4" Titanium Full Range Speaker
Hi What would be the ideal volume for 2 speakers? (I suspect its not just a case of doubling the volume for 1). Also what length and diameter should the vent be? Finally as I am using these for a centre speaker, can I place the vent between the speakers?
Actually it is as simple as doubling the volume for two. I would build the enclosure to 0.2 cubic feet so you end up with 0.18 and use a single 1-1/2" diameter, 3" long port for a tuning frequency of 75 Hz. There is no problem putting the ports between the drivers on the front of the cabinet.

Which option is better for the volume of 0.21 cubic feet, sealed or vented? If vented, what size of port?
The Vas is not the recommended box volume for the driver. The recommended enclosure for this woofer is 0.125 cubic feet with a 1.5" diameter, 6" long port that will tune it to about 75 Hz.

I would like to use 4 of these drivers in a single enclosure. what is the enclosure and port size to achieve the best bass?
.36 cubic feet vented volume of cabinet. The vent will be a bit smaller than one speaker's cone size. Try a smaller vent first and see if you like the bass response. You will get coupling using 4 of these in series/parallel wiring for more than the stated low end response. Too large a vent will "unload" the bottom response--and sound muddy.

Sealed or Vented
Is this driver better suited for a sealed enclosure or a vented enclosure?
These will work in either type but if you want useful bass from it I would recommend venting.

What is the diagonal measurement between mounting holes?
The diagonal distance between screw holes on this driver is 115mm or 4.54".

Enclosure recommendation follow up
An enclosuure of .09 is recommended; is that volume factoring in the space taken up by the port itself and the magnet? In other words, would I have to add the volume of the magnet and the port to the recommended enclosure volume of .09 to arrive at the correct overall enclosure volume?
The 0.09 figure is total box volume. If you build it to 0.09 you will end up with about 0.075 after displacement.
