infinity kappa perfect 12.1 ported box help

[spec 10+ year member]

i normally use factory specs on sub boxes. an installer told me that he could build a ported box bigger than the 1.75 factory recommended and it would sound better. he uses a computer program to design boxes. i will use a punch 360 amp and might move up to a jl500.1 in the future[if i get mine fixed]

i mostly listen to classic rock but jam to r &b and country also. i m mostly looking for sq but also like to loud sometimes. does any one have any experience with this sub in a

ported box. any advice on specs would be great

I've ran the 10 and 12 inch Perfects. I ran the 12's in 2.25 cubes a pc. at around 32 hz. They sounded excellent. I think I could've even went to 2.5. 1.75 is going to choke it out. Excellent subs by the way. I'm getting another pair of 10's soon. Definitely in my top 3.

I ran 2 of those subs in 5 cubes total shared air space tuned to ~35 on a fosgate 1000.1bd. It was one of the best sounding systems I have ever had. Every genre of music sounded great on it. Low bass, high bass, it didn't matter; it all sounded great. This was in a small 2 door hatch back of some sort. I had some crazy door flex on 1000 watts.
