I just bought a 12" RL-s and need to begin to think about the box. I'm stuck between going sealed or ported. I think I want to do ported but if sealed is best for this driver, then so be it. If I do go ported, I'm thinking right now trying 3cuft tuned to 28hz and if I go sealed, I'm thinking around 2.5 cuft or so (going by SS recommendations). Is 28hz too low or should I go higher?

Another question I can throw in here is for power. Single 3 ohm kinda sucks but can be dealt with. Right now I'm thinking about buying a JBL BPX1100.1 (http://www.sonicelectronix.com/item_10482_JBL+BPX1100.1.html) or an older Orion 2500D which I think does somewhere around 1200rms at 3ohms. Anyone have an other amp suggestions for this sub?

Thanks fellas.

28hz should be awesome

As far as power goes, the BPx is a nice choice imo.

If one goes by the SS recommendation of 2.5 ft^3 for sealed, where does that land you in way of Qtc and F3?

And if you want to play around yourself with some software and the rather odd T/S parameters for this driver, how do you go around doing it?
