Box design considerations

[pocketprobe 0]

Hello everyone. I am receiving a 12 inch Q for Christmas which I am rather pleased about because Fi woofers are class...

I was wondering what I should do about a box, the woofer is going in my bedroom instead of a car but all the reviews I have read about the Q lead me to it. It will be used entirely for music, rock, techno, a little pop, and perhaps some rap to show off a little. The room is about 8x10x8 with a chunk removed that is about a 18 inches by 3 feet for a closet, so not a terribly large room.

One of my questions is the great sealed vs ported debate, which would sound better in this application. The Q will be more than plenty in a room this size either way.

I've been prototyping a couple of box designs with WinISD, when I create a box that is 70.7 liters and tuned to 24 hz the response is flat to about 30.16hz, Is this tuned too low considering I do not listen to rap as a rule? Also when I create a box that is sealed and the recommended volume the roll off starts at about 70hz.. Would tweaking the volume change much? I tried Scott's recommendation for 32hz but it makes a large peak there, and doesn't that create boomyness?

Summary:

Fi Q 12 on either 350 or 500w. In a small room in a house looking for quality over quantity. Is sealed better than ported, I don't listen to rap usually.

You don't listen to rap, so you think it is tuned too low? A lot of rap bass is in the 40-50Hz range, because that is where the bass boost works so that silly kids drivin' around with the windows down with their HIGH-TUNED pre-fab boxed subs can destroy things. Not to say that rap doesn't get low... "Put On" by Young Jeezy is apparently 27Hz at lowest...

32 Hz is according to Fi, so I stuck by their recommendations and I love what I got... However, if it peaks there, then I guess go with the curve...
