2-15" BLs vs 1-18" BTL with the same power

[SKEEMASK 3]

Which would be louder? (Daily)

1. (2) fully loaded BL15s with about 3.2ft3 and 50sq" of port "each" tuned to 33Hz..... with a Hifonics Collosus (3200rms x 1@2ohm) so that would be about 1600rms each.

or

2. (1) Fully loaded BTL18 with about 7ft3 and 120sq" of port tuned to 33Hz......pushed off of a Hifonics Collosus also.

the 2 15's would probably be a little louder because of more cone surface area than the 18". I would personally go with 2 18" BL's

Loaded BL15s would do more...

I would but 3.5ft3 -4ft3 after displacement is the biggest I can go and thats kind of small for a 15 but it will do but for a 18.....nah. Id atleast wanna do 5ft3 for a 18
