PR61 Passive Radiator

PR61 is a passive radiator made for FD52 series and Tenacious 6 series. It is based off the Patreon exclusive Tenacious 6+ to help confirm performance. This should also work well with other standard loudspeaker drivers. Printing the  radiator itself with 15% infill will weigh approximately 10g, and add around 7g for a M5 screw and nut. This will be enough for FD52. but you may want to tweak and test. Here is the data for this passive radiator:

Qms:      3.28

Sd:          50.2cm2

Xmax:     4.0mm One Way

Cms:       1.1mm/N

Valiant is the first design I have made incorporating both PR61 and FD52. More designs will happen over time, along with possibly different sizes as well to suit different applications.
