If you want a lot of spl, I would tune it around 40hz.

I have a box design that'll go down low, go up high, and get louder than a ported box //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif PM me if you're interested.

PS: rms is 250 unless you have the ooooooooooooooooold school ones.

ugpm

anyways

250 or 200 depending on where you look

for some reason i wanna say the 06s were 250 and the 07s are 200 again

ive got the spec sheet that came with the woofer sitting in front of me

They haven't changed/updated the spec. sheet in years //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Look at the side of the box.

ahh ok, well im assuming the mic you used is generous...TL youll probably be under 140
