Dayton Audio RSS460HO-4 18" Reference HO Subwoofer 4 ohm
Looking to do a cabinet of around 6 cuft. Want to do a slot port. How big does the port need to be to be tune around 25hz
A port that measures 2"H x 18"W x 28"L will tune that volume to 25 Hz.

I have a 7.5 cubic foot box with 2 three inch flared ports 11" long - for a 15 Hz tuning - using a SPA500 plate amp. If I upgrade to this 18" driver in the same box, should I change the ports - and will my current plate amp work OK?
That volume and port size is actually a 20 Hz tune. I would recommend upping the ports to 4" dual flared at minimum but they would need to be 17" long each in order to maintain a 20 Hz tune. Otherwise this combo should work well.

I wanted to know how much huff and puff I will get if I Put this into a 6 cubic foot net internal with the 6 in precision ports flared port 17 inches long. My sim says that I will get around 46 m/sec of port velocity. Will I get chuffing?
According to my sim the velocity is closer to 25 m/s and that doesn't account for the flared ports. I doubt you will have noise problems.

I see that the db is measured by 2.83v/1m... Can you tell me what the db would be if measured to 1w/1m?
The SPL rating at 1w/1m would be about 89.2 dB.

If this driver is surface mounted--not recessed--how thick does my speaker grill frame need to be so that the fabric does not touch the rubber surround? Thanks
I would recommend a grill that is at least 2" thick to allow for surround clearance.

Sanity check from reading previous questions and answers, but if I'm not mistaken, 3 of these in a 22-ish ft enclosure with 6 total 4 x 17 inch ports would work well? All with their own SPA1000 and own 15amp circuit.
Yes that alignment should work well.
