Battle of the 8s

[ChampN252]

So, I'm looking to do 4 8s under the seat in my sport trac. I had narrowed it down to the sa v3s. But I just discover there are more 8s than i knew about. I really have my eyes on the F8L 8s. The airspace will allow 4 and according to the specs the should pay like my X12s. They also handle a good amount of power. Any better contenders?

Do you have a budget or an amp already picked or is this a blank slate? There are many 8s out there.

Blank slate. I'm looking at the legion 2500. I already a mmats 4 channel.

just wanted to say i had my eye on the psi-8 before purchasing my dc m3 8's. The psi-8's seems to have nice specs specially the 24mm xmax ?

only reason i went with my dc's was price difference after shipping.

I have the SDv2 8's and they work in enclosures of .25ft3 with a lot of output for what it is. I also modeled my 8's in Bassbox pro against the SA8 for small vented enclosure and the SD, for whatever reason, had a better response curve but I'm talking small vented like .4 ft3 after all the bracing, etc was subtracted. Tuned to 30hz it had better response against the E series 8 and the SA but not sure why. Potent little sub in sealed though, just though I'd toss that out.
