2 Fi BL18s

[buick203]

hello guys I'm thinking about getting 2 Fi BL18s. the thing is that I only have about 9.8cuft for both subs available I already took into consideration the port and sub displacement. I'm gonna be running them at 3000w and I came up with an enclosure of 9.8cuft before displacements tuned at 44hz and 4 6"x11" aero ports. I put all my numbers into torres and the port area per foot that I get is around 11.40. I already tried playing around with the tunning but I just cant get it any better. and I cant make the enclosure bigger due to no more room.

are these numbers good? or should I not even try 2 18s with only 4.9cuft per sub

thanks guys

15s would better suit that space. I cant say whether or not the 15s would ultimately be louder than more dispacement in a smaller enclosure.

that's what I was thinking. but from your experience is that to little of space for those subs specifically?

You would be much better off with the 2 fifteens. They would sound better than suffocating those 18s.
