QUICK opinion needed

[maldecido33]

I have a 12" AA Avalanche; box is 2 cu ft net. tuning right at 33 Hz.

should I go with one 4" precision port (~12.56 sq in of port), or two 4" precision ports (~25.1 sq in of port)

need this quick, i have the box built, i just need to throw in either one, or two, ports. :-)

thanks

how much power?

Do 2 ports, less chance of port noise.

orion 1200d @ 1 ohm

so around 1200watts

i've been told by reputable sources the avas can handle up to around 1400w without starting to bottom out

it all depends on enclosure and frequecy....

but you are going to need at least 2 ports

As stated, it really depends on the enclosure. To extend onto that though, don't be so hasty to run 1200 on it. Run the amp at 4 ohms and you'll be very pleased with the results (ps, they really don't gain much output going from ~450 to 1200 watts)

As far as the port situation, if your box is 2 cubes, look to have ~24-30 inches of port area...so two ports would be the way to go over one.
