Tuning a 18"BL

[solobarric 0]

Doing some box designs and wanted a little help on picking what hrtz to tune the box at. I read the post from Fi about tuning and it says anywhere beteween 30-37 hrtz. I will have around 8.5 cuft for each sub and wanted to hear some suggestions on tuning. The enclosure will have the ports facing twords the rear with the subs mounted on the top side of the enclosure. I listin to mostly rap music and want it to be loud as it can be. The subs will be pushed by 2 Alpine PDX 1000.1's for now, but down the road will be pushed by 2 PDX's on each 18 1 on each voice coil at 2ohms for a total of 2000 watts to each sub. Thanks, this site has helped me alot so far, the best site I have come across in a long time.

Is that 8.5 gross or net volume?

I would go for 6.5-7 ft net per sub tuned to 33 Hz. Shoot for 80-100 in^2 of port area per sub.
