obviously a bit less if you account for sub displacement, but its still the size you wanted.

i could model the sub in winisd then recommend an 'optimum' box, but the sub doesnt have any t/s specs.. says a lot about the quality.. not sure how much of an upgrade you're looking for from the jl w1. itll be like upgrading to a base model ek from a base model eg
jl w1=150wrns nom no guts whats so ever..
csp1200 = 400wrms nom

my old vibe blackair mkII that like 5yrs old is better then the w1 tighter and cleaner bass. mind you both subs are in a ported box. the blackair isnt mine anymore...
