2 net 32hz
you will be giving them alot over rated so they will need a bit smaller box
and a decently large port

Check the tutorial section about my thread on rise.

750 for them is still a lot, perhaps not thermally but mechanically. Youll want to account for this in the enclosure.
.5 isnt large for them, but it really isnt small per say.

Good read lol Just read this on woofersect about the sa-8

Quote:
The SA-8 features one of the strongest ferrite motors available on any 8" woofer on the market today. Due to this fact they MUST be utilized in no more than 0.5 to 0.6 cubic foot vented enclosures (or 0.2 to 0.3 cubic foot sealed enclosures) for daily usage
So maybe 2 net @ 32 after all

Well, that number was on a burp setup on ~ 3k. And in a Crx. The only other setup I metered with those (4) was a 4th order armrest blowthrough I did in my Lexus. That one did [email protected] on ~ 3k again. That box was .2/.5/51, in CSS you're wondering.

I did meter a pair in a standard ported in 1cf tuned to 32 in my trunk and it was doing 43's ~ 37hz. That same box did 47's in the Crx at 35hz.
