GRS 4FR-8 Full-Range 4-1/2" Speaker Pioneer Type A11EC80-02F 8 Ohm
The speaker I have is 4 1/2" mounting holes diagonally and 3 1/4" side to side....is this considered a industry standard 4" speaker? I may be looking in the wrong section. Thanks
You will want to measure the cut-out diameter of the hole. There really isn't an industry standard. Parts express shows both the overall diameter and the baffle cutout for the speaker.

Has anyone tried these as replacement drivers for Auratone 5C studio monitor speakers?
I built comparable monitors with these drivers however in larger ported boxes and they perform fantastically.

I'm thinking about putting two of these on a Lepai LP-2020A+ for casual listening of rap/dubstep. I'm a car audio guy, never done anything outside of a car, so I want to know would this be better sealed or ported? And if ported, is 95 HZ what I tune at?
I would recommend porting these, using 0.23 cubic feet for each with a 1" diameter, 1/2" long port (basically a hole in the box if you use 1/2" thick wood for construction). This will tune the box to 88 Hz and give you a bit of a bump around the tuning frequency giving you the perception of more bass, essentially a natural bass boost.

I am replacing a speaker in an old intercom system. The original is a Radio Shack FE-103 8 ohm nom 3 W. The mounting holes measured diagonally center to center are 4.5, outside edge 4.75. Will this speaker work?
The mounting hole centers for this driver are 4-3/4" so it will be a tight fit although I see no reason this will not work if you can get it mounted.

Need to know the mounting hole spacing. Looking for 5" from widest to widest across. Please advise ASAP.
Mounting hole spacing is 4-3/4" on center. The outside edges of the holes are right at 5" and the frame size corner to corner is 5-3/16".

I'm replacing a 6 ohm, 4.5" woofer with a 8 ohm , 4.5" woofer. Is this OK? Should I replace the woofer from the other speaker in the pair?
Replacing a 6 ohm with an 8 ohm will not hurt anything. I would recommend changing both since the overall sound will probably be different.
