I'd rid myself of brand-focus and gadgetry and go with the DIY-advice of poster @mijostyn above. Let physics have their say, and when you buy separate components (certainly electronics) reliability usually sees a clear boost. Cheaper as well.
If DIY is a no-go I'd go with the likes of a duo or quartet of PSA's S1512. Very high quality subs with great pro drivers and good ICEpower amps - way cheaper than both REL and JL Audio to boot.
