GRS 8PF-8 8" Paper Cone Foam Surround Woofer
I have a pair of jbl G500 with 2 8 inch 6 ohm woofers in each box. Would it work ok to put one of these in each box and leave one stock woofer in each box. I would rather get closer to 8 ohm for the overall speaker instead of going lower than the 6 ohm.
That is correct, it is generally better for the amplifier to go up in terms of impedance than going down. As long as the driver physically fits, this should be a solid choice.

Could this woofer be used as a replacement for 1 of the damaged woofers in my 1990's Advent Heritage speakers? I have 2 good woofers in one tower and the plan was to use 1 original and 1 replacement in each. Thanks in advance for your help.
This woofer would work but we do not recommend having two different woofers in the same enclosure.

Need 4 ohm load in an OB project. Would 2 of these work paralleled to get my desired load? Tweeter offset between the two. Desired range is about 80Hz -- 5K. The 4ohm Goldwood doesn't seem to be reviewed with quite the enthusiasm.
These will work well OB down to 80 Hz, although 5k is a stretch for any 8" woofer. I would recommend using a tweeter that can cross lower (maybe 1,800-2kHz), or adding a midrange.

are the grs-8PF-8 8 inch speakers good for a small pa speaker replacement
Probably not. PA and musical instrument speakers have a higher SPL rating than home audio speakers such as the GRS. This means that it will not play nearly as loud as the original speaker, possibly making the high frequency speaker sound over-bearing. Not what you want! Go with a pro-audio type woofer.

How would this woofer perform as mid duty? I have a 12" goldwood woofer that I was planning on using for the lows and I have a few of these sitting around and was wondering if they would work.
Usually an 8" speaker will only play conservatively up to about 2,000 Hz before it starts to beam. If you pick a tweeter that will safely cross this low it should not be a problem.
