SQL sub that hits upper bass notes 45-60 hz well

[DFW40 10+ year member]

I have a Toyota Sequiya with a Fosgate Power T1500bdcp and plenty of room. The subs that I have owned before that hit the upper bass notes with decent authority and accuracy were the JLW6v.2 and IDmax. Are there any other subs out there a bit cheaper that can hit these notes like the other two I mentioned? The acoustics in the large SUV seem to eat up the upper bass notes more than my trunk mounted subs. I have a Sundown 15zv.3 in a 3 cubed box tuned to 36hz that sounded good in my last car but not good in the SUV. I am open to sealed or ported options. The FIQ seems to be a good option but have not heard one in years.
