Answer 1

It's been awhile since I looked but I think I saw them sold on partsexpress.com.  I ordered other things from them and have had no problems.

Lightning Audio's patented PNR Aeroport kit. It's a port tube that comes with flared end caps to eliminate annoying "port turbulence," the low-pitched whistling noise common with ordinary cylindrical port tubes. When you eliminate the distortion turbulence causes, you can turn up your subwoofer volume a lot higher and still get clean sound.

Each PNR port measures 4" in diameter (5-9/16" diameter hole required) and 12" long. The instructions tell you how to trim, assemble and install your PNR port.
