Fi Btl Sub Enclosure
#14
Two L5 12's - 86.9 dB (+3 dB starting point with two @ 89.9 dB) / 600W RMS / 1200W total / 226 square inches of cone area
BTL 15 D1 sensitivity - 93.2 dB / 2000W RMS / 176 square inches of cone area
50 square inches of cone area is an 8" subs worth, which isn't going to make up for +1300W power handling & the +3.3 dB starting point
For every +3 dB you either need to double the cone area or power, in your case it'll be like having four ported L5 12's on 600W each, but the four 12's would be better below the port tune because of sheer cone area.
What'd you power the L5's with?
