Which will have better SQL/SPL? one jl 13w7 or 3 diamond audio 10 d9's?

Question

given that each will be in a near perfect setup with ideal enclosure and amp/s

Answer 1

i would go with the jbl they are overall a better brand and would sound tight

one single jl subwoofer will give you penty of that bass

but if you want more spl go with the 3 diamond audios more surface area and more amps = louder

Answer 2

SQL would probrobly be the JL but the three DAs will kill the JL in SPL

Answer 3

3 10"s will be louder then 1 13". and because there diamond 10"s they'll even sound better.

good luck
