Dayton Audio PA130-8 5" Full Range PA Driver
I have a pair of JBL J50's, the 5" woofers are shot beyond needing new foam. I like sharp solid bass and i drive them with clean power. Crossover is 2200Hz, tweets are fine, the PA130-8 at 90 hz is not as low as stock, will I be thrilled with these?
Unfortunately I cannot say how you will like a certain item as a replacement. These will probably not have the low end the old ones did even with the same enclosure tuning, but they will more than likely be more sensitive. You will also want to verify the woofer frame diameter, this Dayton is about 5.2", so if the JBL is exactly 5" you may have to modify the enclosure.

Based off a previous question, the recommended vented volume for a single woofer is .26 cubic feet. What would it be for two woofers per vented box? To clarify, would it simply be double the volume or how does that work?
Yes when you double the number of drivers you simply double the volume of the enclosure and number of ports for the same tuning frequency and F3.

I am going to try these for optimus 77 speaker replacements. The woofer in these is 5 inch round about 2 5/8 deep I can cut the 2 side down a little to make them fit but what is the hole spacing on these. I can always redrill if needed.
The hole spacing on this driver is 4.75".

I want to build an aura-clone, ive seen a diy article minus dimensions with this speaker, can you help with proper size for optimum response. cordially don ward
I am not familiar with that particular design, but the recommend vented box for this woofer is .26 cubic feet. With a 1-1/2" diameter, 2-1/4" long port the tuning frequency will be about 73 Hz and provide a flat response.

what size speaker box for 4 of these?
I would like to build apair of sealed boxes with 4 of these speakers in each wired in series parallel to remain 8 ohms.i will be sending the lows(100 hz and lower)to subs so I don't need fantastic bass response and would like to make the boxes as small as possible to hang from my ceiling.
Four of these require only 0.27 cubic feet for the flattest response.

What size cabinet for 2 of them for small PA or Monitors?
I was thinking about running 2 of these with a tweeter for some small PA tops. What size cabinet world work best? Ported, sealed?Thanks!
If two woofers and a tweeter - have the tweeter on top and vertical or you will have crossover and phase issues. D'Apolito designs are challenging... You need to google search a box calculator. Plug in the T/S specs and you will see the difference in response curves for both ported and sealed. Some speakers lend themselves better to one or the other. You will see by the specs. If sealed, and you want accurate sound, go for a total Qts of .707
