Deciding between subs for SPL

Hi, I am trying to pick a 15in sub for SPL. I am limited to 1000w RMS and am stuck between these.

https://soundqubed.com/product/hds3-1-selection/
https://ficaraudio.com/product/xv3-series-x15/
https://www.amazon.com/gp/product/B0095YVCF4/

Which will give me more dB SPL? And if you know of a different sub that would suit my needs better please let me know.

Edit: Or would this give me more SPL if I just powered it at 1000w instead of the rated 1250w? https://ficaraudio.com/product/ssd-series-ssd15/

Thanks!

Thanks!
The second FI you linked to has a higher sensitivity rating, but, without knowing if it was measured in series or parallel, I can't tell you if it's better. The other two had no T/S specs to look at. I assume you'll be running ported, so Xmax won't be a big factor, look at sensitivity ratings.

Thanks for the advice.

So due to the higher sensitivity of the SSD it should be louder even when slightly below rated power? And I would like to get an even more sensitive sub (90+dB) but have not had much luck finding quality choices.

When comparing the 2 Fi subs, I asked almost that exact question to Fi about 2 weeks ago. They said the output would be very similar at the same watts but the SSD would be a little smoother than the EV3.

Yeah, when given the same 1000 watts, a sub with higher sensitivity will be louder. You probably won't find a good quality, high spl sub with good sensitivity.
Google "spl calculator" and "spl calculator xls". Those will help you wrap your head around the relationship between sensitivity, power, and spl.
