Need help with a "Big Brand" choice

Okay, she wants the Infinity 12s. I've been trying to plug these numbers in to WinISD but it's telling me a 2.6 cu ft. box tuned to 24hz. I'm sort of a novice at this, but is that right? Infinity says 2 cu ft. tuned to 32hz. But they also say a 4x10" round port and that doesn't exactly come out to 32hz either.

Ah the Infinity Reference 12s brings me back to my second set of subs I ever owned....good memories. She'll be happy with them they can hold a little more power than they are rated and they are clean lows-highs. I'd tune them to 32hz

Yeah, Was thinking 32-33hz, but volume?

 
sorry at work can't do calculator right now, I imagine about 2ft^3 is about right, they will be clean they just don't get very low. tight bass though.
Well, she's into rock, alternative, country, so they will probably will suit her fine.
