Vifa TC9FD-18-08 3-1/2" Full Range Paper Cone Woofer
Hi Guys, I am thinking about using this as a car midrange mounted high up in the door, now a 3.5 FR pioneer 2way around 89dB Bass is 88 dB 6.5 Alpine. Will this be loud enough or do I need to say with car 4 ohm drivers? 12-9-14 Thanks!
It is hard to say. These will be higher and more on axis so the difference in sensitivity might be beneficial here for a better blend. This will have similar sensitivity to other similar sized drivers.

Baffle cutout is listed as 3.3 inches, which leaves gaps beyond the frame. Actual value approximately 3.05 in. Possibly supposed to be 3.03 and dropped the zero?
Yes this is incorrect. The actual driver cutout is 3", I will have the site updated.

I've just purchased a pair of the Vifa TC9FD'S for th sole purpose of making a scaled down version of The Paul Voight - Tapered Quarter Wave Tube system. But I have to ask: do I need to install a filter of some type between th amp and th Vifa driver?
I am not familiar with that design specifically. If the driver is being used full range, a contour filter will help with baffle step and create a smoother response, but ultimately it will be up to you and how you like the sound. Not having a filter will not hurt anything as long as the driver is not overpowered.

So I put the specs into a calculator and it was giving me all these crazy readings. So what would be a good size and port dimensions for these in order to make them into good computer monitors.
The recommended vented box volume for this driver is 0.206 cubic feet with a 1-1/2" diameter, 1-5/8" long port for a tuning frequency of 89 Hz.

Would a 3.5" hole saw be too big of a hole for this speaker?
Unfortunately yes, the frame itself measures 3.5" so it will likely not seal properly if a 3.5" hole saw is used.
