Well i got a decent amount of money back on my taxes so its time for a new system. I have decided on a bl 15 dual 1 ohm and I just want to make sure i got this right. My enclosure is 3.5 cuft after all displacement tuned to 32hz using two 4" tube ports each 15" long. I also will be using a memphis 1500d (1500 watts at 2 ohms). Does all that sound good? Any advice on what options I should add to the sub when ordering? Thanks guys I appreciate it.

I come up with the port as 16". . .not much difference.

I would make the ports 17" long and use the Precision Sound Ports:

With that much power, I would spec:

Ohm: dual 1

P Chamfer: no

Cooling: yes +$40

Flatwind: yes +$20

Daily or SPL: Daily

Extreme Lead: no

Universal: yes
