Rap is a very generic term. What kindof rap? A lot of older rap/hip-hop from my experience doesnt have much low end extension, so a low tuning that most will recommend would only be wasting output in trade for something you wont use.
Can you give us some song examples?

If you are using a 4" port I would suggest to use tape and just cut it down maybe 1" at a time until you start to find that happy medium you like. Much easier then just guessing and gluing it all together and then your stuck and have to buy a new port.

mostly newer rap like lil wayne, wiz kahlifa, waka flacka, stuff like that.
